HTML::Clean - Cleans up HTML code for web browsers, not humans
use HTML::Clean; $h = new HTML::Clean($filename); # or.. $h = new HTML::Clean($htmlcode); $h->compat(); $h->strip(); $data = $h->data(); print $$data;
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:
The entire proces is configurable, so you can pick and choose what you want to clean.
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.
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.
Get/set the optimization level. $level is a number from 1 to 9.
Returns the current HTML data as a scalar reference.
Removes excess space from HTML
You can control the optimizations used by specifying them in the %options hash reference.
The following options are recognized:
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'
This function improves the cross-platform compatibility of your HTML. Currently checks for the following problems:
This function converts pages created with Microsoft Frontpage to something a Unix server will understand a bit better. This function currently does the following:
