XPath(3) User Contributed Perl Documentation XPath(3)NAMEXML::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 $_->getValue, "\n" foreach (@nodes);
DESCRIPTIONXML::DOM::XPath allows you to use XML::XPath methods to query a DOM.
This is often much easier than relying only on getElementsByTagName.
It lets you use all of the XML::DOM methods.
METHODS
Those methods can be applied to a whole dom object or to a node.
findnodes($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.
