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