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
31       return a list of nodes found by $path.
32
33       findnodes_as_string($path)
34
35       return the nodes found reproduced as XML. The result is not guaranteed
36       to be valid XML though.
37
38       findvalue($path)
39
40       return the concatenation of the text content of the result nodes
41
42       exists($path)
43
44       return true if the given path exists.
45
46       matches($path)
47
48       return true if the node matches the path.
