# 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.
