+  e1.parent # => nil
+  e1.parent = e0
+  e1.parent # => <foo/>
+
+==== Task: Insert Previous Sibling
+
+Use method {Child#previous_sibling=}[../../../../REXML/Parent.html#method-i-previous_sibling-3D]
+to insert a previous sibling:
+
+  xml_string = '<root><a/><c/></root>'
+  d = REXML::Document.new(xml_string)
+  d.root.to_a   # => [<a/>, <c/>]
+  c = d.root[1] # => <c/>
+  b = REXML::Element.new('b')
+  c.previous_sibling = b
+  d.root.to_a   # => [<a/>, <b/>, <c/>]
+
+==== Task: Insert Next Sibling
+
+Use method {Child#next_sibling=}[../../../../REXML/Parent.html#method-i-next-sibling-3D]
+to insert a previous sibling:

+  xml_string = '<root><a/><c/></root>'
+  d = REXML::Document.new(xml_string)
+  d.root.to_a   # => [<a/>, <c/>]
+  a = d.root[0] # => <a/>

+  a.next_sibling = b
+  d.root.to_a   # => [<a/>, <b/>, <c/>]
+
+=== Removal or Replacement
+
+==== Task: Remove Child from Parent

+  xml_string = '<root><a/><b/><c/></root>'
+  d = REXML::Document.new(xml_string)
+  d.root.to_a       # => [<a/>, <b/>, <c/>]
+  b = d.root[1]     # => <b/>
+  d = REXML::Element.new('d')

+
+Use method {Child#document}[../../../../REXML/Parent.html#method-i-document]

+  xml_string = '<root><a/><b/><c/></root>'
+  d = REXML::Document.new(xml_string)
+  d.root.to_a     # => [<a/>, <b/>, <c/>]
+  b = d.root[1]   # => <b/>
+  b.document == d # => true
