tags and I would like to clean them up a bit. For instance:

Answer 1

Here is something you can use. The first line finds whenever there is 2 or more
tags (with whitespace between and different types) and replace them with wellformated

.

I also included the second line to clean up the rest of the
tags if you want that too.

function clean($txt)
{
    $txt=preg_replace("{(|\/>)\s*){2,}}i", "

", $txt);
    $txt=preg_replace("{(|\/>)\s*)}i", "
", $txt);
    return $txt;
}
