+      #
+      # [Parameters]
+      # - +selector_list+ (String)
+      #
+      #   The CSS selector to be translated into XPath. This is always a String, but that string
+      #   value may be a {selector list}[https://www.w3.org/TR/selectors-4/#grouping] (see
+      #   examples).
+      #
+      # [Keyword arguments]
+      # - +prefix:+ (String)
+      #
+      #   The XPath expression prefix which determines the search context. See Nokogiri::XML::XPath
+      #   for standard options. Default is +XPath::GLOBAL_SEARCH_PREFIX+.
+      #
+      # - +ns:+ (Hash<String ⇒ String>, nil)
+      #
+      #   Namespaces that are referenced in the query, if any. This is a hash where the keys are the
+      #   namespace prefix and the values are the namespace URIs. Default is +nil+ indicating an
+      #   empty set of namespaces.
+      #
+      # - +visitor:+ (Nokogiri::CSS::XPathVisitor)
+      #
+      #   Use this XPathVisitor object to transform the CSS AST into XPath expressions. See
+      #   Nokogiri::CSS::XPathVisitor for more information on some of the complex behavior that can
+      #   be customized for your document type. Default is +Nokogiri::CSS::XPathVisitor.new+.
+      #
+      #   ⚠ Note that this option is mutually exclusive with +prefix+ and +ns+. If +visitor+ is
+      #   provided, +prefix+ and +ns+ must not be present.
+      #
+      # - +cache:+ (Boolean)
+      #
+      #   Whether to use the SelectorCache for the translated query to ensure that repeated queries
+      #   don't incur the overhead of re-parsing the selector. Default is +true+.
+      #
+      # [Returns] (Array<String>) The equivalent set of XPath expressions for +selector_list+
+      #
+      # *Example* with a simple selector:
+      #

+module Nokogiri
+  # Convenience method for Nokogiri::HTML5::Document.parse
+  def self.HTML5(...)
+    Nokogiri::HTML5::Document.parse(...)
+  end
+
+  # == Usage
+  #
+  # Parse an HTML5 document:
+  #
+  #   doc = Nokogiri.HTML5(input)
+  #
+  # Parse an HTML5 fragment:
+  #
+  #   fragment = Nokogiri::HTML5.fragment(input)
+  #
+  # ⚠ HTML5 functionality is not available when running JRuby.
+  #
+  # == Parsing options
+  #
+  # The document and fragment parsing methods support options that are different from
+  # Nokogiri::HTML4::Document or Nokogiri::XML::Document.
+  #
+  # - <tt>Nokogiri.HTML5(input, url:, encoding:, **parse_options)</tt>
+  # - <tt>Nokogiri::HTML5.parse(input, url:, encoding:, **parse_options)</tt>
+  # - <tt>Nokogiri::HTML5::Document.parse(input, url:, encoding:, **parse_options)</tt>
+  # - <tt>Nokogiri::HTML5.fragment(input, encoding:, **parse_options)</tt>
+  # - <tt>Nokogiri::HTML5::DocumentFragment.parse(input, encoding:, **parse_options)</tt>
+  #
+  # The four currently supported parse options are
+  #
+  # - +max_errors:+ (Integer, default 0) Maximum number of parse errors to report in HTML5::Document#errors.
+  # - +max_tree_depth:+ (Integer, default +Nokogiri::Gumbo::DEFAULT_MAX_TREE_DEPTH+) Maximum tree depth to parse.
+  # - +max_attributes:+ (Integer, default +Nokogiri::Gumbo::DEFAULT_MAX_ATTRIBUTES+) Maximum number of attributes to parse per element.
+  # - +parse_noscript_content_as_text:+ (Boolean, default false) When enabled, parse +noscript+ tag content as text, mimicking the behavior of web browsers.
+  #
+  # These options are explained in the following sections.
+  #
+  # === Error reporting: +max_errors:+
+  #
+  # Nokogiri contains an experimental HTML5 parse error reporting facility. By default, no parse
+  # errors are reported but this can be configured by passing the +:max_errors+ option to
+  # HTML5.parse or HTML5.fragment.
+  #
+  # For example, this script:
+  #
+  #   doc = Nokogiri::HTML5.parse('<span/>Hi there!</span foo=bar />', max_errors: 10)
+  #   doc.errors.each do |err|
+  #     puts(err)
+  #   end
+  #
+  # Emits:
+  #
+  #   1:1: ERROR: Expected a doctype token
+  #   <span/>Hi there!</span foo=bar />
+  #   ^
+  #   1:1: ERROR: Start tag of nonvoid HTML element ends with '/>', use '>'.
+  #   <span/>Hi there!</span foo=bar />
+  #   ^
+  #   1:17: ERROR: End tag ends with '/>', use '>'.
+  #   <span/>Hi there!</span foo=bar />
+  #                   ^
+  #   1:17: ERROR: End tag contains attributes.
+  #   <span/>Hi there!</span foo=bar />
+  #                   ^
+  #
+  # Using <tt>max_errors: -1</tt> results in an unlimited number of errors being returned.
+  #
+  # The errors returned by HTML5::Document#errors are instances of Nokogiri::XML::SyntaxError.
+  #
+  # The {HTML standard}[https://html.spec.whatwg.org/multipage/parsing.html#parse-errors] defines a
+  # number of standard parse error codes. These error codes only cover the "tokenization" stage of
+  # parsing HTML. The parse errors in the "tree construction" stage do not have standardized error
+  # codes (yet).
+  #
+  # As a convenience to Nokogiri users, the defined error codes are available
+  # via Nokogiri::XML::SyntaxError#str1 method.
+  #
+  #   doc = Nokogiri::HTML5.parse('<span/>Hi there!</span foo=bar />', max_errors: 10)
+  #   doc.errors.each do |err|
+  #     puts("#{err.line}:#{err.column}: #{err.str1}")
+  #   end
+  #   doc = Nokogiri::HTML5.parse('<span/>Hi there!</span foo=bar />',
+  #   # => 1:1: generic-parser
+  #   #    1:1: non-void-html-element-start-tag-with-trailing-solidus
+  #   #    1:17: end-tag-with-trailing-solidus
+  #   #    1:17: end-tag-with-attributes
+  #
+  # Note that the first error is +generic-parser+ because it's an error from the tree construction
+  # stage and doesn't have a standardized error code.
+  #
+  # For the purposes of semantic versioning, the error messages, error locations, and error codes
+  # are not part of Nokogiri's public API. That is, these are subject to change without Nokogiri's
+  # major version number changing. These may be stabilized in the future.
+  #
+  # === Maximum tree depth: +max_tree_depth:+
+  #
+  # The maximum depth of the DOM tree parsed by the various parsing methods is configurable by the
+  # +:max_tree_depth+ option. If the depth of the tree would exceed this limit, then an
+  # +ArgumentError+ is thrown.
+  #
+  # This limit (which defaults to +Nokogiri::Gumbo::DEFAULT_MAX_TREE_DEPTH+) can be removed by
+  # giving the option <tt>max_tree_depth: -1</tt>.
+  #
+  #   html = '<!DOCTYPE html>' + '<div>' * 1000
+  #   doc = Nokogiri.HTML5(html)
+  #   # raises ArgumentError: Document tree depth limit exceeded
+  #   doc = Nokogiri.HTML5(html, max_tree_depth: -1)
+  #
+  # === Attribute limit per element: +max_attributes:+
+  #
+  # The maximum number of attributes per DOM element is configurable by the +:max_attributes+
+  # option. If a given element would exceed this limit, then an +ArgumentError+ is thrown.
+  #
+  # This limit (which defaults to +Nokogiri::Gumbo::DEFAULT_MAX_ATTRIBUTES+) can be removed by
+  # giving the option <tt>max_attributes: -1</tt>.
+  #
+  #   html = '<!DOCTYPE html><div ' + (1..1000).map { |x| "attr-#{x}" }.join(' # ') + '>'
+  #   # "<!DOCTYPE html><div attr-1 attr-2 attr-3 ... attr-1000>"
+  #   doc = Nokogiri.HTML5(html)
+  #   # raises ArgumentError: Attributes per element limit exceeded
+  #
+  #   doc = Nokogiri.HTML5(html, max_attributes: -1)
+  #   # parses successfully
+  #
+  # === Parse +noscript+ elements' content as text: +parse_noscript_content_as_text:+
+  #
+  # By default, the content of +noscript+ elements is parsed as HTML elements. Browsers that
+  # support scripting parse the content of +noscript+ elements as raw text.
+  #
+  # The +:parse_noscript_content_as_text+ option causes Nokogiri to parse the content of +noscript+
+  # elements as a single text node.
+  #
+  #   html = "<!DOCTYPE html><noscript><meta charset='UTF-8'><link rel=stylesheet href=!></noscript>"
+  #   doc = Nokogiri::HTML5.parse(html, parse_noscript_content_as_text: true)
+  #   pp doc.at_xpath("/html/head/noscript")
+  #   # => #(Element:0x878c {
+  #   #        name = "noscript",
+  #   #        children = [ #(Text "<meta charset='UTF-8'><link rel=stylesheet href=!>")]
+  #   #      })
+  #
+  # In contrast, <tt>parse_noscript_content_as_text: false</tt> (the default) causes the +noscript+
+  # element in the previous example to have two children, a +meta+ element and a +link+ element.
+  #
+  #   doc = Nokogiri::HTML5.parse(html)
+  #   puts doc.at_xpath("/html/head/noscript")
+  #   # => #(Element:0x96b4 {
+  #   #      name = "noscript",
+  #   #      children = [
+  #   #        #(Element:0x97e0 { name = "meta", attribute_nodes = [ #(Attr:0x990c { name = "charset", value = "UTF-8" })] }),
+  #   #        #(Element:0x9b00 {
+  #   #          name = "link",
+  #   #          attribute_nodes = [
+  #   #            #(Attr:0x9c2c { name = "rel", value = "stylesheet" }),
+  #   #            #(Attr:0x9dd0 { name = "href", value = "!" })]
+  #   #          })]
+  #   #      })
+  #
+  # == HTML Serialization
+  #
+  # After parsing HTML, it may be serialized using any of the Nokogiri::XML::Node serialization
+  # methods. In particular, XML::Node#serialize, XML::Node#to_html, and XML::Node#to_s will
+  # serialize a given node and its children. (This is the equivalent of JavaScript's
+  # +Element.outerHTML+.) Similarly, XML::Node#inner_html will serialize the children of a given
+  # node. (This is the equivalent of JavaScript's +Element.innerHTML+.)
+  #
+  #   doc = Nokogiri::HTML5("<!DOCTYPE html><span>Hello world!</span>")
+  #   puts doc.serialize
+  #   # => <!DOCTYPE html><html><head></head><body><span>Hello world!</span></body></html>
+  #
+  # Due to quirks in how HTML is parsed and serialized, it's possible for a DOM tree to be
+  # serialized and then re-parsed, resulting in a different DOM. Mostly, this happens with DOMs
+  # produced from invalid HTML. Unfortunately, even valid HTML may not survive serialization and
+  # re-parsing.
+  #
+  # In particular, a newline at the start of +pre+, +listing+, and +textarea+
+  # elements is ignored by the parser.
+  #
+  #   doc = Nokogiri::HTML5(<<-EOF)
+  #   <!DOCTYPE html>
+  #   <pre>
+  #   Content</pre>
+  #   EOF
+  #   puts doc.at('/html/body/pre').serialize
+  #   # => <pre>Content</pre>
+  #
+  # In this case, the original HTML is semantically equivalent to the serialized version. If the
+  # +pre+, +listing+, or +textarea+ content starts with two newlines, the first newline will be
+  # stripped on the first parse and the second newline will be stripped on the second, leading to
+  # semantically different DOMs. Passing the parameter <tt>preserve_newline: true</tt> will cause
+  # two or more newlines to be preserved. (A single leading newline will still be removed.)
+  #
+  #   doc = Nokogiri::HTML5(<<-EOF)
+  #   <!DOCTYPE html>
+  #   <listing>
+  #
+  #   Content</listing>
+  #   EOF
+  #   puts doc.at('/html/body/listing').serialize(preserve_newline: true)
+  #   # => <listing>
+  #   #
+  #   #    Content</listing>
+  #
+  # == Encodings
+  #
+  # Nokogiri always parses HTML5 using {UTF-8}[https://en.wikipedia.org/wiki/UTF-8]; however, the
+  # encoding of the input can be explicitly selected via the optional +encoding+ parameter. This is
+  # most useful when the input comes not from a string but from an IO object.
+  #
+  # When serializing a document or node, the encoding of the output string can be specified via the
+  # +:encoding+ options. Characters that cannot be encoded in the selected encoding will be encoded
+  # as {HTML numeric
+  # entities}[https://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references].
+  #
+  #   frag = Nokogiri::HTML5.fragment('<span>아는 길도 물어가라</span>')
+  #   html = frag.serialize(encoding: 'US-ASCII')
+  #   puts html
+  #   # => <span>&#xc544;&#xb294; &#xae38;&#xb3c4; &#xbb3c;&#xc5b4;&#xac00;&#xb77c;</span>
+  #
+  #   frag = Nokogiri::HTML5.fragment(html)
+  #   puts frag.serialize
+  #   # => <span>아는 길도 물어가라</span>
+  #
+  # (There's a {bug}[https://bugs.ruby-lang.org/issues/15033] in all current versions of Ruby that
+  # can cause the entity encoding to fail. Of the mandated supported encodings for HTML, the only
+  # encoding I'm aware of that has this bug is <tt>'ISO-2022-JP'</tt>. We recommend avoiding this
+  # encoding.)
+  #
+  # == Notes
+  #
+  # * The Nokogiri::HTML5.fragment function takes a String or IO and parses it as a HTML5 document
+  #   in a +body+ context. As a result, the +html+, +head+, and +body+ elements are removed from
+  #   this document, and any children of these elements that remain are returned as a
+  #   Nokogiri::HTML5::DocumentFragment; but you can pass in a different context (e.g., "html" to
+  #   get +head+ and +body+ tags in the result).
+  #
+  # * The Nokogiri::HTML5.parse function takes a String or IO and passes it to the
+  #   <code>gumbo_parse_with_options</code> method, using the default options.  The resulting Gumbo
+  #   parse tree is then walked.
+  #
+  # * Instead of uppercase element names, lowercase element names are produced.
+  #
+  # * Instead of returning +unknown+ as the element name for unknown tags, the original tag name is
+  #   returned verbatim.

+    # Nokogiri builder can be used for building XML and HTML documents.
+    #
+    # == Synopsis:
+    #
+    #   builder = Nokogiri::XML::Builder.new do |xml|
+    #     xml.root {
+    #       xml.products {
+    #         xml.widget {
+    #           xml.id_ "10"
+    #           xml.name "Awesome widget"
+    #         }
+    #       }
+    #     }
+    #   end
+    #   puts builder.to_xml
+    #
+    # Will output:
+    #
+    #   <?xml version="1.0"?>
+    #   <root>
+    #     <products>
+    #       <widget>
+    #         <id>10</id>
+    #         <name>Awesome widget</name>
+    #       </widget>
+    #     </products>
+    #   </root>
+    #
+    #
+    # === Builder scope
+    #
+    # The builder allows two forms.  When the builder is supplied with a block
+    # that has a parameter, the outside scope is maintained.  This means you
+    # can access variables that are outside your builder.  If you don't need
+    # outside scope, you can use the builder without the "xml" prefix like
+    # this:
+    #
+    #   builder = Nokogiri::XML::Builder.new do
+    #     root {
+    #       products {
+    #         widget {
+    #           id_ "10"
+    #           name "Awesome widget"
+    #         }
+    #       }
+    #     }
+    #   end
+    #
+    # == Special Tags
+    #
+    # The builder works by taking advantage of method_missing.  Unfortunately
+    # some methods are defined in ruby that are difficult or dangerous to
+    # remove.  You may want to create tags with the name "type", "class", and
+    # "id" for example.  In that case, you can use an underscore to
+    # disambiguate your tag name from the method call.
+    #
+    # Here is an example of using the underscore to disambiguate tag names from
+    # ruby methods:
+    #
+    #   @objects = [Object.new, Object.new, Object.new]
+    #
+    #   builder = Nokogiri::XML::Builder.new do |xml|
+    #     xml.root {
+    #       xml.objects {
+    #         @objects.each do |o|
+    #           xml.object {
+    #             xml.type_   o.type
+    #             xml.class_  o.class.name
+    #             xml.id_     o.id
+    #           }
+    #         end
+    #       }
+    #     }
+    #   end
+    #   puts builder.to_xml
+    #
+    # The underscore may be used with any tag name, and the last underscore
+    # will just be removed.  This code will output the following XML:
+    #
+    #   <?xml version="1.0"?>
+    #   <root>
+    #     <objects>
+    #       <object>
+    #         <type>Object</type>
+    #         <class>Object</class>
+    #         <id>48390</id>
+    #       </object>
+    #       <object>
+    #         <type>Object</type>
+    #         <class>Object</class>
+    #         <id>48380</id>
+    #       </object>
+    #       <object>

+    #       </object>
+    #     </objects>
+    #   </root>
+    #
+    # == Tag Attributes
+    #
+    # Tag attributes may be supplied as method arguments.  Here is our
+    # previous example, but using attributes rather than tags:
+    #
+    #   @objects = [Object.new, Object.new, Object.new]
+    #
+    #   builder = Nokogiri::XML::Builder.new do |xml|
+    #     xml.root {
+    #       xml.objects {
+    #         @objects.each do |o|
+    #           xml.object(:type => o.type, :class => o.class, :id => o.id)
+    #         end
+    #       }
+    #     }
+    #   end
+    #   puts builder.to_xml
+    #
+    # === Tag Attribute Short Cuts
+    #
+    # A couple attribute short cuts are available when building tags.  The
+    # short cuts are available by special method calls when building a tag.
+    #
+    # This example builds an "object" tag with the class attribute "classy"
+    # and the id of "thing":
+    #
+    #   builder = Nokogiri::XML::Builder.new do |xml|
+    #     xml.root {
+    #       xml.objects {
+    #         xml.object.classy.thing!
+    #       }
+    #     }
+    #   end
+    #   puts builder.to_xml
+    #
+    # Which will output:
+    #
+    #   <?xml version="1.0"?>
+    #   <root>
+    #     <objects>
+    #       <object class="classy" id="thing"/>
+    #     </objects>
+    #   </root>
+    #
+    # All other options are still supported with this syntax, including
+    # blocks and extra tag attributes.
+    #
+    # == Namespaces
+    #
+    # Namespaces are added similarly to attributes.  Nokogiri::XML::Builder
+    # assumes that when an attribute starts with "xmlns", it is meant to be
+    # a namespace:
+    #
+    #   builder = Nokogiri::XML::Builder.new { |xml|
+    #     xml.root('xmlns' => 'default', 'xmlns:foo' => 'bar') do
+    #       xml.tenderlove
+    #     end
+    #   }
+    #   puts builder.to_xml
+    #
+    # Will output XML like this:
+    #
+    #   <?xml version="1.0"?>
+    #   <root xmlns:foo="bar" xmlns="default">
+    #     <tenderlove/>
+    #   </root>
+    #
+    # === Referencing declared namespaces
+    #
+    # Tags that reference non-default namespaces (i.e. a tag "foo:bar") can be
+    # built by using the Nokogiri::XML::Builder#[] method.
+    #
+    # For example:
+    #
+    #   builder = Nokogiri::XML::Builder.new do |xml|
+    #     xml.root('xmlns:foo' => 'bar') {
+    #       xml.objects {
+    #         xml['foo'].object.classy.thing!
+    #       }
+    #     }
+    #   end
+    #   puts builder.to_xml
+    #
+    # Will output this XML:
+    #
+    #   <?xml version="1.0"?>
+    #   <root xmlns:foo="bar">
+    #     <objects>
+    #       <foo:object class="classy" id="thing"/>
+    #     </objects>
+    #   </root>
+    #
+    # Note the "foo:object" tag.
+    #
+    # === Namespace inheritance
+    #
+    # In the Builder context, children will inherit their parent's namespace. This is the same
+    # behavior as if the underlying {XML::Document} set +namespace_inheritance+ to +true+:
+    #
+    #   result = Nokogiri::XML::Builder.new do |xml|
+    #     xml["soapenv"].Envelope("xmlns:soapenv" => "http://schemas.xmlsoap.org/soap/envelope/") do
+    #       xml.Header
+    #     end
+    #   end
+    #   result.doc.to_xml
+    #   # => <?xml version="1.0" encoding="utf-8"?>
+    #   #    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
+    #   #      <soapenv:Header/>
+    #   #    </soapenv:Envelope>
+    #
+    # Users may turn this behavior off by passing a keyword argument +namespace_inheritance:false+
+    # to the initializer:
+    #
+    #   result = Nokogiri::XML::Builder.new(namespace_inheritance: false) do |xml|
+    #     xml["soapenv"].Envelope("xmlns:soapenv" => "http://schemas.xmlsoap.org/soap/envelope/") do
+    #       xml.Header
+    #       xml["soapenv"].Body # users may explicitly opt into the namespace
+    #     end
+    #   end
+    #   result.doc.to_xml
+    #   # => <?xml version="1.0" encoding="utf-8"?>
+    #   #    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
+    #   #      <Header/>
+    #   #      <soapenv:Body/>
+    #   #    </soapenv:Envelope>
+    #
+    # For more information on namespace inheritance, please see {XML::Document#namespace_inheritance}
+    #
+    #
+    # == Document Types
+    #
+    # To create a document type (DTD), use the Builder#doc method to get
+    # the current context document.  Then call Node#create_internal_subset to
+    # create the DTD node.
+    #
+    # For example, this Ruby:
+    #
+    #   builder = Nokogiri::XML::Builder.new do |xml|
+    #     xml.doc.create_internal_subset(
+    #       'html',
+    #       "-//W3C//DTD HTML 4.01 Transitional//EN",
+    #       "http://www.w3.org/TR/html4/loose.dtd"
+    #     )
+    #     xml.root do
+    #       xml.foo
+    #     end
+    #   end
+    #
+    #   puts builder.to_xml
+    #
+    # Will output this xml:
+    #
+    #   <?xml version="1.0"?>
+    #   <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

+      #   node is used as the wrapper.
+      # - *node* (Nokogiri::XML::Node)
+      #   An element that is `#dup`ed and used as the wrapper.
+      #
+      # [Returns] +self+, to support chaining.
+      #
+      # ⚠ Note that if a +String+ is passed, the markup will be parsed <b>once per node</b> in the
+      # NodeSet. You can avoid this overhead in cases where you know exactly the wrapper you wish to
+      # use by passing a +Node+ instead.
+      #
+      # Also see Node#wrap
+      #
+      # *Example* with a +String+ argument:

+      #   doc = Nokogiri::HTML5(<<~HTML)
+      #     <html><body>
+      #       <a>a</a>

+    # Options that control the parsing behavior for XML::Document, XML::DocumentFragment,
+    # HTML4::Document, HTML4::DocumentFragment, XSLT::Stylesheet, and XML::Schema.
+    #
+    # These options directly expose libxml2's parse options, which are all boolean in the sense that
+    # an option is "on" or "off".
+    #
+    # 💡 Note that HTML5 parsing has a separate, orthogonal set of options due to the nature of the
+    # HTML5 specification. See Nokogiri::HTML5.
+    #
+    # ⚠ Not all parse options are supported on JRuby. Nokogiri will attempt to invoke the equivalent
+    # behavior in Xerces/NekoHTML on JRuby when it's possible.
+    #
+    # == Setting and unsetting parse options
+    #
+    # You can build your own combinations of parse options by using any of the following methods:
+    #
+    # [ParseOptions method chaining]
+    #
+    #   Every option has an equivalent method in lowercase. You can chain these methods together to
+    #   set various combinations.
+    #
+    #     # Set the HUGE & PEDANTIC options
+    #     po = Nokogiri::XML::ParseOptions.new.huge.pedantic
+    #     doc = Nokogiri::XML::Document.parse(xml, nil, nil, po)
+    #
+    #   Every option has an equivalent <code>no{option}</code> method in lowercase. You can call these
+    #   methods on an instance of ParseOptions to unset the option.
+    #
+    #     # Set the HUGE & PEDANTIC options
+    #     po = Nokogiri::XML::ParseOptions.new.huge.pedantic
+    #
+    #     # later we want to modify the options
+    #     po.nohuge # Unset the HUGE option
+    #     po.nopedantic # Unset the PEDANTIC option
+    #
+    #   💡 Note that some options begin with "no" leading to the logical but perhaps unintuitive
+    #   double negative:
+    #
+    #     po.nocdata # Set the NOCDATA parse option
+    #     po.nonocdata # Unset the NOCDATA parse option
+    #
+    #   💡 Note that negation is not available for STRICT, which is itself a negation of all other
+    #   features.
+    #
+    #
+    # [Using Ruby Blocks]
+    #
+    #   Most parsing methods will accept a block for configuration of parse options, and we
+    #   recommend chaining the setter methods:
+    #
+    #     doc = Nokogiri::XML::Document.parse(xml) { |config| config.huge.pedantic }
+    #
+    #
+    # [ParseOptions constants]
+    #
+    #   You can also use the constants declared under Nokogiri::XML::ParseOptions to set various
+    #   combinations. They are bits in a bitmask, and so can be combined with bitwise operators:
+    #
+    #     po = Nokogiri::XML::ParseOptions.new(Nokogiri::XML::ParseOptions::HUGE | Nokogiri::XML::ParseOptions::PEDANTIC)
+    #     doc = Nokogiri::XML::Document.parse(xml, nil, nil, po)

+    # SAX Parsers are event-driven parsers.
+    #
+    # Two SAX parsers for XML are available, a parser that reads from a string or IO object as it
+    # feels necessary, and a parser that you explicitly feed XML in chunks. If you want to let
+    # Nokogiri deal with reading your XML, use the Nokogiri::XML::SAX::Parser. If you want to have
+    # fine grain control over the XML input, use the Nokogiri::XML::SAX::PushParser.
+    #
+    # If you want to do SAX style parsing of HTML, check out Nokogiri::HTML4::SAX.
+    #
+    # The basic way a SAX style parser works is by creating a parser, telling the parser about the
+    # events we're interested in, then giving the parser some XML to process. The parser will notify
+    # you when it encounters events you said you would like to know about.
+    #
+    # To register for events, subclass Nokogiri::XML::SAX::Document and implement the methods for
+    # which you would like notification.
+    #
+    # For example, if I want to be notified when a document ends, and when an element starts, I
+    # would write a class like this:
+    #
+    #   class MyHandler < Nokogiri::XML::SAX::Document
+    #     def end_document
+    #       puts "the document has ended"

+    #       puts "#{name} started"

+      # The SAX::Document class is used for registering types of events you are interested in
+      # handling. All of the methods on this class are available as possible events while parsing an
+      # \XML document. To register for any particular event, subclass this class and implement the
+      # methods you are interested in knowing about.
+      #
+      # To only be notified about start and end element events, write a class like this:
+      #
+      #     class MyHandler < Nokogiri::XML::SAX::Document
+      #       def start_element name, attrs = []
+      #         puts "#{name} started!"
+      #       end
+      #
+      #       def end_element name
+      #         puts "#{name} ended"
+      #       end
+      #     end
+      #
+      # You can use this event handler for any SAX-style parser included with Nokogiri.
+      #

+      # ### Entity Handling
+      #
+      # ⚠ Entity handling is complicated in a SAX parser! Please read this section carefully if
+      # you're not getting the behavior you expect.
+      #
+      # Entities will be reported to the user via callbacks to #characters, to #reference, or
+      # possibly to both. The behavior is determined by a combination of _entity type_ and the value
+      # of ParserContext#replace_entities. (Recall that the default value of
+      # ParserContext#replace_entities is `false`.)
+      #
+      # ⚠ <b>It is UNSAFE to set ParserContext#replace_entities to `true`</b> when parsing untrusted
+      # documents.
+      #
+      # 💡 For more information on entity types, see [Wikipedia's page on
+      # DTDs](https://en.wikipedia.org/wiki/Document_type_definition#Entity_declarations).
+      #
+      # | Entity type                          | #characters                        | #reference                          |
+      # |--------------------------------------|------------------------------------|-------------------------------------|
+      # | Char ref (e.g., <tt>&#146;</tt>)     | always                             | never                               |
+      # | Predefined (e.g., <tt>&amp;</tt>)    | always                             | never                               |
+      # | Undeclared †                         | never                              | <tt>#replace_entities == false</tt> |
+      # | Internal                             | always                             | <tt>#replace_entities == false</tt> |
+      # | External †                           | <tt>#replace_entities == true</tt> | <tt>#replace_entities == false</tt> |
+      #
+      # &nbsp;
+      #
+      # † In the case where the replacement text for the entity is unknown (e.g., an undeclared entity
+      # or an external entity that could not be resolved because of network issues), then the
+      # replacement text will not be reported. If ParserContext#replace_entities is `true`, this
+      # means the #characters callback will not be invoked. If ParserContext#replace_entities is
+      # `false`, then the #reference callback will be invoked, but with `nil` for the `content`
+      # argument.

+      # 💡 Some XPath syntax is supported in CSS queries. For example, to query for an attribute:
+      #
+      #   node.css('img > @href') # returns all +href+ attributes on an +img+ element
+      #   node.css('img / @href') # same

+      #   node.css('div @class')
+      #
+      #   node.css
+      #
+      # 💡 Array-like syntax is supported in CSS queries as an alternative to using +:nth-child()+.
+      #
+      # ⚠ NOTE that indices are 1-based like +:nth-child+ and not 0-based like Ruby Arrays. For
+      # example:
+      #
+      #   # equivalent to 'li:nth-child(2)'
+      #   node.css('li[2]') # retrieve the second li element in a list
+      #
+      # ⚠ NOTE that the CSS query string is case-sensitive with regards to your document type. HTML
+      # tags will match only lowercase CSS queries, so if you search for "H1" in an HTML document,
+      # you'll never find anything. However, "H1" might be found in an XML document, where tags
+      # names are case-sensitive (e.g., "H1" is distinct from "h1").
