NAME¶

HTML::Tidy - (X)HTML validation in a Perl object

VERSION¶

Version 1.50

SYNOPSIS¶

    use HTML::Tidy;
    my $tidy = HTML::Tidy->new( {config_file => 'path/to/config'} );
    $tidy->ignore( type => TIDY_WARNING, typed => TIDY_INFO );
    $tidy->parse( "foo.html", $contents_of_foo );
    for my $message ( $tidy->messages ) {
        print $message->as_string;
    }

DESCRIPTION¶

"HTML::Tidy" is an HTML checker in a handy dandy object. It's meant as a replacement for HTML::Lint. If you're currently an HTML::Lint user looking to migrate, see the section "Converting from HTML::Lint".

EXPORTS¶

Message types "TIDY_ERROR", "TIDY_WARNING" and "TIDY_INFO". Everything else is an object method.

METHODS¶

new()¶

Create an HTML::Tidy object.

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

Optionally you can give a hashref of configuration parms.

    my $tidy = HTML::Tidy->new( {config_file => 'path/to/tidy.cfg'} );

This configuration file will be read and used when you clean or parse an HTML file. You can also pass options directly to libtidy.

    my $tidy = HTML::Tidy->new( {
                                    output_xhtml => 1,
                                    tidy_mark => 0,
                                } );

See <http://tidy.sourceforge.net/docs/quickref.html> or "tidy -help-config" for the list of options supported by libtidy. The following options are not supported by "HTML::Tidy": quiet

messages()¶

Returns the messages accumulated.

clear_messages()¶

Clears the list of messages, in case you want to print and clear, print and clear. If you don't clear the messages, then each time you call parse() you'll be accumulating more in the list.

ignore( parm => value [, parm => value ] )¶

Specify types of messages to ignore. Note that the ignore flags must be set before calling "parse()". You can call "ignore()" as many times as necessary to set up all your restrictions; the options will stack up.

•

type => TIDY_INFO|TIDY_WARNING|TIDY_ERROR

 

Specifies the type of messages you want to ignore, either info or warnings or errors. If you wanted, you could call ignore on all three and get no messages at all.

 

    $tidy->ignore( type => TIDY_WARNING );
    

•

text => qr/regex/

•

text => [ qr/regex1/, qr/regex2/, ... ]

 

Checks the text of the message against the specified regex or regexes, and ignores the message if there's a match. The value for the text parm may be either a regex, or a reference to a list of regexes.

 

    $tidy->ignore( text => qr/DOCTYPE/ );
    $tidy->ignore( text => [ qr/unsupported/, qr/proprietary/i ] );
    

parse( $filename, $str [, $str...] )¶

Parses a string, or list of strings, that make up a single HTML file. The $filename parm is only used as an identifier for your use. The file is not actually read and opened. Returns true if all went OK, or false if there was some problem calling tidy, or parsing tidy's output.

clean( $str [, $str...] )¶

Cleans a string, or list of strings, that make up a single HTML file. Returns the cleaned string as a single string.

INSTALLING LIBTIDY¶

HTML::Tidy requires that "libtidy" be installed on your system. You can obtain libtidy through your distribution's package manager (make sure you install the development package with headers), or from the libtidy website at <http://tidy.sourceforge.net/src/tidy_src.tgz>.

CONVERTING FROM "HTML::Lint"¶

HTML::Tidy is different from HTML::Lint in a number of crucial ways.

•

It's not pure Perl

 

"HTML::Tidy" is mostly a happy wrapper around libtidy.

•

The real work is done by someone else

 

Changes to libtidy may come down the pipe that I don't have control over. That's the price we pay for having it do a darn good job.

•

It's no longer bundled with its "Test::" counterpart

 

HTML::Lint came bundled with "Test::HTML::Lint", but Test::HTML::Tidy is a separate distribution. This saves the people who don't want the "Test::" framework from pulling it in, and all its prerequisite modules.
