NAME

6       XML::DOM::XPath - Perl extension to add XPath support to XML::DOM,
7       using XML::XPath engine
8

SYNOPSIS

10         use XML::DOM::XPath;
11
12         my $parser= XML::DOM::Parser->new();
13         my $doc = $parser->parsefile ("file.xml");
14
15         # print all HREF attributes of all CODEBASE elements
16         # compare with the XML::DOM version to see how much easier it is to use
17         my @nodes = $doc->findnodes( '//CODEBASE[@HREF]/@HREF');
18         print $_->getValue, "\n" foreach (@nodes);
19

DESCRIPTION

21       XML::DOM::XPath allows you to use XML::XPath methods to query a DOM.
22       This is often much easier than relying only on getElementsByTagName.
23
24       It lets you use all of the XML::DOM methods.
25

METHODS

27       Those methods can be applied to a whole dom object or to a node.
28
29   findnodes($path)
30       return a list of nodes found by $path.
31
32   findnodes_as_string($path)
33       return the nodes found reproduced as XML. The result is not guaranteed
34       to be valid XML though.
35
36   findvalue($path)
37       return the concatenation of the text content of the result nodes
38
39   exists($path)
40       return true if the given path exists.
41
42   matches($path)
43       return true if the node matches the path.
