XML::DOM::XPath



NAME

XML::DOM::XPath - Perl extension to add XPath support to XML::DOM, using XML::XPath engine


SYNOPSIS

  use XML::DOM::XPath;
  my $parser= XML::DOM::Parser->new();
  my $doc = $parser->parsefile ("file.xml");
  # print all HREF attributes of all CODEBASE elements
  # compare with the XML::DOM version to see how much easier it is to use
  my @nodes = $doc->findnodes( '//CODEBASE[@HREF]/@HREF');
  print $_->getValue, "\n" foreach (@nodes);


DESCRIPTION

XML::DOM::XPath allows you to use XML::XPath methods to query a DOM. This is often much easier than relying only on getElementsByTagName.

It lets you use all of the XML::DOM methods.


METHODS

Those methods can be applied to a whole dom object or to a node.

findnodes($path)

return a list of nodes found by $path.

findnodes_as_string($path)

return the nodes found reproduced as XML. The result is not guaranteed to be valid XML though.

findvalue($path)

return the concatenation of the text content of the result nodes

exists($path)

return true if the given path exists.

matches($path)

return true if the node matches the path.


SEE ALSO

  XML::DOM
