Hi Matt. Thanks for your bug fixes. I'll make the necessary changes and upload the new version. I might as well add support for namespaces while I'm at it.

Re. the licensing, I haven't put it under one yet, but you can do pretty much anything you want with this.

Actually, you can just ignore these elements with the ignore property.

Like the core PHP strip_tags function this class requires you to define what attributes you want to keep. For example if you have the following html

<div style="background: red;"><div>

You could remove the style attributes simply by running the following code, where $str is the above html snippet:

$sa = new StripAttributes();
$str = $sa->strip( $str );

If there are some attributes you want to preserve, you can define them like so:

$sa = new StripAttributes();
$sa->allow = array( 'id', 'class' );
$str = $sa->strip( $str );

In that example any id and class attributes will be preserved.

You can find out more about the functionality of this class by reading the above documentation.

Hi Will,
No that will break it in PHP 4.

You need to add the key in the foreach and then modify the $nodes array using the key to find the current node, like this:

private function findAttributes( $nodes ) {
	
	# Extract attributes
	foreach( $nodes as $key => $node ) {
		preg_match_all( "/([^ =]+)\s*=\s*[\"|']{0,1}([^\"']*)[\"|']{0,1}/i", $node['attributes'], $attributes );
		#print_r( $attributes[1] );
		if( $attributes[1] ) {
			foreach( $attributes[1] as $att_key => $att ) {
				$literal = $attributes[0][$att_key];
				$attribute_name = $attributes[1][$att_key];
				$value = $attributes[2][$att_key];
				$atts[] = array( 'literal' => $literal, 'name' => $attribute_name, 'value' => $value );
			}
		}
		else
			$nodes[$key]['attributes'] = null;
		
		$nodes[$key]['attributes'] = $atts;
		unset( $atts );
	}
	
	return $nodes;
}

Hi,

This is a small bug that has now been fixed.

A more elegant way to do this would be to use the DOM API, but it is not good at parsing poorly formated documents.
