This object will create a Meta::Ds::Graph for you from an xml definition for a graph structure. This object extends XML::Parser and there is no doubt that this is the right way to go about implementing such an object (all the handles get the parser which is $self if you extend the parser which makes them methods and everything is nice and clean from there on...). The reason we dont inherit from XML::Parser is that the parser which actually gets passed to the handlers is XML::Parser::Expat (which is the low level object) and we inherit from that to get more object orientedness.

new($)

This gives you a new object for a parser.

get_result($)

This method will retrieve the result of the parsing process.

handle_start($$)

This will handle start tags. This will create new objects according to the context.

handle_end($$)

This will handle end tags.

handle_char($$)

This will handle actual text. This currently, according to context, sets attributes for the various objects.

TEST($)

Test suite for this module.

XML::Parser::Expat(3)

None.
