XML::Parser::Lite::TreUserPContributed Perl DXML::Parser::Lite::Tree::XPath(3)NAMEXML::Parser::Lite::Tree::XPath - XPath access to
XML::Parser::Lite::Tree structures
SYNOPSIS
use XML::Parser::Lite::Tree;
use XML::Parser::Lite::Tree::XPath;
my $parser = new XML::Parser::Lite::Tree(process_ns => 1);
my $tree = $parser->parse($xml);
my $xpath = new XML::Parser::Lite::Tree::XPath($tree);
my $nodes = $xpath->select_nodes('/aaa');
my $nodes = $xpath->select_nodes('/*/*/parent::*');
my $nodes = $xpath->select_nodes('//ccc[ position() = floor(last() div 2 + 0.5) or position() = ceiling(last() div 2 + 0.5) ]');
DESCRIPTION
This pure-Perl implementation of XPath is a complement to
XML::Parser::Lite::Tree, a pure-Perl XML tree parser and builder. It
aims to implement 100% of the W3C XPath specification.
METHODS
"new( $tree )"
The constructor returns a new XPath parser for the given tree.
"query( $path )"
Returns a XML::Parser::Lite::Tree::XPath::Result object containing
the result of the query.
"select_nodes( $path )"
A convinience function around "query()" which returns 0 unless the
result is a nodeset, else returns the value of the nodeset.
