Hi,
Thanks for answering the question. That shows that that is not bug in
boost::regex. But I have one more thing to ask. Ofcourse when the
dependancy on external file is removed boost::regex is working fine. When
you ran the code with the string directly from the file, did your regex pick
the second one ? You can certainly think that this is a question not to be
answered by a busy person like you. You might choose to ignore this
question. But if you can, please answer this. Also please tell me which
version of boost library are you using? I am running the code in a linux
machine and the code i already sent is not picking the second one.
Thanks
Kiran.
