NAME

6       HTML::TreeBuilder::LibXML - HTML::TreeBuilder and XPath compatible
7       interface with libxml
8

SYNOPSIS

10           use HTML::TreeBuilder::LibXML;
11
12           my $tree = HTML::TreeBuilder::LibXML->new;
13           $tree->parse($html);
14           $tree->eof;
15
16           # $tree and $node compatible to HTML::Element
17           my @nodes = $tree->findvalue($xpath);
18           for my $node (@nodes) {
19               print $node->tag;
20               my %attr = $node->all_external_attr;
21           }
22
23           HTML::TreeBuilder::LibXML->replace_original(); # replace HTML::TreeBuilder::XPath->new
24

DESCRIPTION

26       HTML::TreeBuilder::XPath is libxml based compatible interface to
27       HTML::TreeBuilder, which could be slow for a large document.
28
29       HTML::TreeBuilder::LibXML is drop-in-replacement for
30       HTML::TreeBuilder::XPath.
31
32       This module doesn't implement all of HTML::TreeBuilder and
33       HTML::Element APIs, but enough methods are defined so modules like
34       Web::Scraper work.
