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

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

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.

This is a benchmark result by tools/benchmark.pl

    Web::Scraper: 0.26
    HTML::TreeBuilder::XPath: 0.09
    HTML::TreeBuilder::LibXML: 0.01_01
