Well, you can simply look for a closing bracket (>) followed by only white
space characters (space, tab, return) followed by an open bracket (<) and,
if there's a match, strip out the white space in between them. That would
turn:
<tr>
<td>
into just <tr><td>
You'd have to check for a bit more, such as <pre> and <code> tags, but it's
not an unreasonable regex to write. What I am more concerned about is; I'm
assuming everything would have to be encased within <?php ?> tags, meaning
all HTML would have to be properly escaped, etc. *that* would be a major
pain, so I hope I'm overlooking something.
