Please do not post links to URL shorteners on this forum. Either post the code here, or, if the code is too long, work on your code to reduce it to a small, self-contained program that still exhibits the problem.	[reply]

Seems to me you have a Java problem, not a Perl one.	[reply]

IIRC there are different possible RegEx libs in Java. Maybe you just need to look for Perl compatibility. Cheers Rolf	[reply]

You realize that if we were to help you do this abominable thing, we'd all be committing a cardinal sin against Perl? That said, when I help my Java friends debug their regex problems, the most common problem they have is that they have to put their regex's in strings. So you can't just say something simple like \s, but you had to \\s all the characters that have special meaning (like \ and quotes and such). That might be your problem... dunno... Now I'm going to go take a shower. I feel dirty.	[reply]

You're right. I think, I couldn't tell you what I exactly need. When I try to compile the regular expression over there in Perl, the result is perfect. But if I compile it in Java, it doesn't work. Do you have any suggestion for me?	[reply]

You don't even tell us what problem you have with your Java code. This is not a code writing service, neither for Perl nor for Java. We will maybe help you with formulating the regular expression in a way that Java understands the Perl regular expression. But we don't know Java here, in general, so you will have to learn both if you want to translate from one to the other.	[reply]

The perl side is straightforward, just use perlre to decipher all the parts of the regex. First look up the flags "gxm" at the end that change some details of how the regex works.	[reply]
