Yes, it can do what you want. The question is - are you getting any
matches? I'm far from an expert on regex's, but it looks like you
aren't getting any matches.
If the code is as you indicate, you should, however. What happens if you
print $tagpart and $emesg?
Also - do you get any output after the call to preg_replace_callback
(just to make sure there isn't a runtime error you aren't seeing)?
