NAME

HTML::Tidy::libXML - Tidy HTML via XML::LibXML

VERSION

$Id: libXML.pm,v 0.2 2009/02/21 11:47:58 dankogai Exp dankogai $

SYNOPSIS

use HTML::Tidy::libXML;
my $tidy = HTML::Tidy::libXML->new();
my $xml   = $tidy->clean($html, $encoding);    # clean enough as xml
my $xhtml = $tidy->clean($html, $encoding, 1); # clean enough for browsers

EXPORT

none.

Functions

new

Creates an object.

my $tidy = HTML::Tidy::libXML->new();

html2dom

my $dom = $tidy->html2dom($string, $encoding);

This is analogus to

my $lx = XML::LibXML->new;
$lx->recover_silently(1);
my $dom = $lx->parse_html_string($string);

Except one major difference. HTML::Tidy::LibXML does not trust <meta http-equiv="content-type" content="text/html; charset="foo"> while XML::LibXML tries to use one. Consider this;

my $dom = $lx->parse_html_string('http://example.com');

This kinda works since XML::LibXML is capable of fetching document directly. But XML::LibXML does not honor HTTP header. Here is the better practice.

require LWP::UserAgent;
require HTTP::Response::Encoding;
my $uri = shift || die;
my $res = LWP::UserAgent->new->get($uri);
die $res->status_line unless $res->is_success;
my $dom = $tidy->html2dom($res->content, $res->encoding);

dom2xml

my $tidy->com2xml($dom, $level);

Tidies $dom which is XML::LibXML::Document object and returns an XML string. If the level is ommitted, the resulting XML is good enough as XML -- valid but not very browser compliant (like <br clear="">, <a name="here" />). Set level to 1 or above for tidier, browser-compliant xhtml.

html2xml

my $xml = $tidy->html2xml($html, $encoding, $level)

Which is the shorthand for:

my $dom = $tidy->html2dom($html, $encoding);
my $xml = $tidy->dom2xml($dom, $level);

clean

An alias to html2xml.

BENCHMARK

This is what happened trying to tidy http://www.perl.com/ on my PowerBook Pro. See t/bench.pl for details.
