I built something similar to the situation that you are describing.
One difference though is I used preg_replace_callback
(http://us2.php.net/preg_replace_callback) so that I can do custom
scripting with the matched string to be replaced.
I know I'm entering this discussion a bit late, but one tool that I've
found indispensible in writing regular expressions (even after knowing
how to write them) is The Regex Coach (http://www.weitz.de/regex-coach)
(Free, and runs on Windows and Linux).
Essentially, you paste the text to search into the bottom textbox, and
then start typing your regular expression into the top one. As you type,
it shows you what it is matching in the bottom one. It can also show you
what individual submatches are matching, and all sorts of neat stuff.
So, if I have an HTML web page and I want to suck some specific
information out of it, I'll paste the information in, write up a regex,
and make sure it's matching what it's supposed to. But the feedback AS
you're typing it is super handy. For example, if I have a regex, and I
add a "[a-z]", then the indicator will show it matching the next
character, then if I add "*", the text selection will expand to show it
matching the rest of the letters, and so on.
Anyhow, I find the feedback as I write a regex to be addictively useful.
