DESCRIPTION

This is a subclass of WWW::Mechanize that provides an XML DOM accessor which parses the contents of the response and returns it as a XML::LibXML::Document. The motivation for developing this module was to facilitate testing of XML APIs and XHTML web pages.

METHODS

new( %options )

Creates a new WWW::Mechanize::XML object with the specified options. This constructor method accepts all of the arguments accepted by WWW::Mechanize - see WWW::Mechanize for further details. Other optional arguments accepted by this method are xml_parser_options and xml_error_options:

xml_parser_options

This argument, if specified, must be a hashref of valid XML::LibXML::Parser options which will be used to instantiate the XML parser. If no parser options are specified defaults are used. Please see the documentation for XML::LibXML::Parser for option descriptions and default values. Valid parser options accepted are:

validation

recover

recover_silently

expand_entities

keep_blanks

pedantic_parser

line_numbers

load_ext_dtd

complete_attributes

expand_xinclude

clean_namespaces

xml_error_options

This argument, if specified, must be a hashref containing at least the trigger_xpath key. If there is a value for the given xpath expression it will cause the call to xml() to die with that value. If a trigger_value key is specified the call will only die if the value at trigger_xpath equals trigger_value. If a message_xpath key is specified the call to xml() will die with the value at that path.

xml( )

Returns a XML::LibXML::Document object created from the response content by calling the XML::LibXML::Parser parse_string() method. Any parsing errors will propogate up. If xml_error_options were specified for this instance the response document is check for errors accordingly - this method will die if errors are found in the document as specified by the options.
