Well... the reason for this is obvious (sadly enough):
RegExp does NOT support replacing backreferences...
> any suggestions would be appreciated.
I faced the same problem a few weeks ago and since I wanted to stick with the
"lightweight" regexp, I implemented backrefs for myself. It's not yet
"completely complete" (mostly, escaping backslashes is still missing). I'm
planning to take another look at it soon, finish it and also submit the code...
(along with a few other fixes and extensions)
Right now, I implemented the functionality by subclassing rather than modifying
RE.java (assuming there might be updates, I didn't want to "merge" my changes
:-)
If you (or anybody else?) want to have the sources, just send me an e-mail...
If you prefer using "standard packages", I guess you could use ORO...
HTH,
Holger
