HTML::TreeBuilder::LibXML(3pm)				User Contributed Perl Documentation			    HTML::TreeBuilder::LibXML(3pm)

NAME

       HTML::TreeBuilder::LibXML - HTML::TreeBuilder and XPath compatible interface with libxml

SYNOPSIS

	   use HTML::TreeBuilder::LibXML;

	   my $tree = HTML::TreeBuilder::LibXML->new;
	   $tree->parse($html);
	   $tree->eof;

	   # $tree and $node compatible to HTML::Element
	   my @nodes = $tree->findvalue($xpath);
	   for my $node (@nodes) {
	       print $node->tag;
	       my %attr = $node->all_external_attr;
	   }

	   HTML::TreeBuilder::LibXML->replace_original(); # replace HTML::TreeBuilder::XPath->new

DESCRIPTION

       HTML::TreeBuilder::XPath is libxml based compatible interface to HTML::TreeBuilder, which could be slow for a large document.

       HTML::TreeBuilder::LibXML is drop-in-replacement for HTML::TreeBuilder::XPath.

       This module doesn't implement all of HTML::TreeBuilder and HTML::Element APIs, but enough methods are defined so modules like Web::Scraper
       work.

BENCHMARK

       This is a benchmark result by tools/benchmark.pl

	       Web::Scraper: 0.26
	       HTML::TreeBuilder::XPath: 0.09
