There's a quote that sometimes goes around the internet, something like 
this: "Sometimes a programmer who is confronted with a problem solves it 
with regex.  Now the programmer has two problems."

Regex is not the sharpest tool in the programmers toolbox.  It was 
intended to be used once, on a command line like with the grep tool, and 
then tossed away.

Take the time to write a parser to do what you want.  It'll probably be 
faster both ways:  you could write a parser faster than trying to figure 
out what regex you need to use, and regex is interpreted, whereas 
parsers can be optimized directly to machine code.  Win-win, and that's 
before taking into account the trouble maintenance programmers will have 
deciphering this regex.
