INVALID HTML TAG ATTRIBUTES

Hello
I was wondering whether somebody has a function that would first, strip invalid attributes like "align" on an image tag and 2nd add e.g. the "alt" attribute if it’s missing.

Unfortunately, I’m not good at this regexp stuff.

Hope somebody can help.

Thank you in advance for your input!!

I think I’m getting a little closer by using some of this stuff:

<?php
// fix RSS feed
$str = '...';
$output = str_replace('Weiterlesen...', $str, $output);
// remove invalid align attribute
$align = '/align=["\'](left|right)["\']/';
$output = preg_replace($align, '', $output);

// remove class tags
$class = '/class=["\']([^"\']+)["\']/';
$output = preg_replace($class, '', $output);

$options = '<img>';
return $modx->stripTags($output, $options);
?>

I’m sure there are better ways to do it - however, I would still very much appreciate some input on how this cleanup could be achieved and what’s more important how I could an "alt" attribute if it’s missing on the image tag.

thanks

TinyMCE should prompt you to enter the alt text or are you trying to do this without using tiny?

I’m not using tinyMCE at all and the code I’m after is to clean up an RSS feed.
