NAME

       HTML::Clean - Cleans up HTML code for web browsers, not humans

SYNOPSIS

         use HTML::Clean;
         $h = new HTML::Clean($filename); # or..
         $h = new HTML::Clean($htmlcode);

         $h->compat();
         $h->strip();
         $data = $h->data();
         print $$data;

DESCRIPTION

       The HTML::Clean module encapsulates a number of common techniques for minimizing the size
       of HTML files.  You can typically save between 10% and 50% of the size of a HTML file
       using these methods.  It provides the following features:

       Remove unneeded whitespace (begining of line, etc)
       Remove unneeded META elements.
       Remove HTML comments (except for styles, javascript and SSI)
       Replace tags with equivilant shorter tags (<strong> --> <b>)
       etc.

       The entire proces is configurable, so you can pick and choose what you want to clean.

THE HTML::Clean CLASS

       $h = new HTML::Clean($dataorfile, [$level]);

       This creates a new HTML::Clean object.  A Prerequisite for all other functions in this
       module.

       The $dataorfile parameter supplies the input HTML, either a filename, or a reference to a
       scalar value holding the HTML, for example:

         $h = new HTML::Clean("/htdocs/index.html");
         $html = "<strong>Hello!</strong>";
         $h = new HTML::Clean(\$html);

       An optional 'level' parameter controls the level of optimization performed.  Levels range
       from 1 to 9.  Level 1 includes only simple fast optimizations.  Level 9 includes all
       optimizations.

       $h->initialize($dataorfile)

       This function allows you to reinitialize the HTML data used by the current object.  This
       is useful if you are processing many files.

       $dataorfile has the same usage as the new method.

       Return 0 for an error, 1 for success.

       $h->level([$level])

       Get/set the optimization level.  $level is a number from 1 to 9.

       $myref = $h->data()

       Returns the current HTML data as a scalar reference.

       strip(\%options);

       Removes excess space from HTML

       You can control the optimizations used by specifying them in the %options hash reference.

       The following options are recognized:

       boolean values (0 or 1 values)
                 whitespace    Remove excess whitespace
                 shortertags   <strong> -> <b>, etc..
                 blink         No blink tags.
                 contenttype   Remove default contenttype.
                 comments      Remove excess comments.
                 entities      &quot; -> ", etc.
                 dequote       remove quotes from tag parameters where possible.
                 defcolor      recode colors in shorter form. (#ffffff -> white, etc.)
                 javascript    remove excess spaces and newlines in javascript code.
                 htmldefaults  remove default values for some html tags
                 lowercasetags translate all HTML tags to lowercase

       parameterized values
                 meta        Takes a space separated list of meta tags to remove,
                             default "GENERATOR FORMATTER"

                 emptytags   Takes a space separated list of tags to remove when there is no
                             content between the start and end tag, like this: <b></b>.
                             The default is 'b i font center'

       Please note that if your HTML includes preformatted regions (this means, if it includes
       <pre>...</pre>, we do not suggest removing whitespace, as it will alter the rendered
       defaults.

       HTML::Clean will print out a warning if it finds a preformatted region and is requested to
       strip whitespace. In order to prevent this, specify that you don't want to strip
       whitespace - i.e.

         $h->strip( {whitespace => 0} );

       compat()

       This function improves the cross-platform compatibility of your HTML.  Currently checks
       for the following problems:

       Insuring all IMG tags have ALT elements.
       Use of Arial, Futura, or Verdana as a font face.
       Positioning the <TITLE> tag immediately after the <head> tag.

       defrontpage();

       This function converts pages created with Microsoft Frontpage to something a Unix server
       will understand a bit better.  This function currently does the following:

       Converts Frontpage 'hit counters' into a unix specific format.
       Removes some frontpage specific html comments
