User Contributed Perl Documentation XML::LibXML::XPathExpression(3) 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).
