# Nokogiri XML parser for soap4r.
|
|
#
|
|
# Nokogiri may be used as the XML parser in soap4r. Require 'xsd/xmlparser/nokogiri' in your
|
|
# soap4r applications, and soap4r will use Nokogiri as its XML parser. No other changes should
|
|
# be required to use Nokogiri as the XML parser.
|
|
#
|
|
# Example (using UW ITS Web Services):
|
|
#
|
|
# require 'rubygems'
|
|
# require 'nokogiri'
|
|
# gem 'soap4r'
|
|
# require 'defaultDriver'
|
|
# require 'xsd/xmlparser/nokogiri'
|
|
#
|
|
# obj = AvlPortType.new
|
|
# obj.getLatestByRoute(obj.getAgencies.first, 8).each do |bus|
|
|
# p "#{bus.routeID}, #{bus.longitude}, #{bus.latitude}"
|
|
# end
|
|
