html::clean

HTML::Clean(3pm)					User Contributed Perl Documentation					  HTML::Clean(3pm)

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
