XML::LibXML::XPathExprUseroContributed Perl DXML::LibXML::XPathExpression(3pm)

NAME
       XML::LibXML::XPathExpression - XML::LibXML::XPathExpression - interface
       to libxml2 pre-compiled XPath expressions

SYNOPSIS
	 use XML::LibXML;
	 my $compiled_xpath = XML::LibXML::XPathExpression->new('//foo[@bar="baz"][position()<4]');

	 # interface from XML::LibXML::Node

	 my $result = $node->find($compiled_xpath);
	 my @nodes = $node->findnodes($compiled_xpath);
	 my $value = $node->findvalue($compiled_xpath);

	 # interface from XML::LibXML::XPathContext

	 my $result = $xpc->find($compiled_xpath,$node);
	 my @nodes = $xpc->findnodes($compiled_xpath,$node);
	 my $value = $xpc->findvalue($compiled_xpath,$node);

	 $compiled = XML::LibXML::XPathExpression->new( xpath_string );

DESCRIPTION
       This is a perl interface to libxml2's pre-compiled XPath expressions.
       Pre-compiling an XPath expression can give in some performance benefit
       if the same XPath query is evaluated many times.
       "XML::LibXML::XPathExpression" objects can be passed to all "find..."
       functions "XML::LibXML" that expect an XPath expression.

       new()
	     $compiled = XML::LibXML::XPathExpression->new( xpath_string );

	   The constructor takes an XPath 1.0 expression as a string and
	   returns an object representing the pre-compiled expressions (the
	   actual data structure is internal to libxml2).
