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.
