I guess you haven't tried visual regexp. It marks the regexp parts and 
what it matches with distinct colors - Look at the screenshot. The 
C++-code looks like syntax highlighting. But visual regexp does the 
coloring automatically just by looking at the regexp. For example, the 
word "template" is colored blue, because it was matched by \w+ (also 
colored blue in the expression).

Your tool seems to only extract pure text. This can be done using sed, e.g.:

	sed 's/(.* some re)/place \1 here/'

The \1 is replaced with the first () group, \2 with the second etc. From 
within Python, you can use re.sub, which also accepts backreferences.
