Need Regular Expression Help

I want to parse the following string into 3 parts per match. I almost got
it, but my expression has a flaw in it.
I tried this, but didn't quite work the way I expect on the second match b/c
there's no space before the symbol.

<§\s(.*?)\s*;?\s(.*?)\s*>(.*?)</§>

You must<§ Control.exe; Printers>add a printer</§from the <§
Control.exe>control panel</§>.

Anyone know of a good forum to goto for help with regular expressions?

Thanks,
Lee

Hi Lee,

This is one of my favorite references on Regular Expressions:

I found that http://www.regular-expressions.info is a good reference.

So I came up with this expression, which works according to Regex Coach
http://weitz.de/regex-coach
But it throws an exception at runtime in C#.

<§\s+(.*?)\s*(?(?=;);\s*(.*?)\s*|(?))>(.*?)</§>

You must <§ Control.exe; Printers>add a printer</§from the <§
Control.exe>control panel</§>.

Still trying to figure it out.
