Not all regexes are the same. Different regex engines accept different symbols, and sometimes behave differently, or have different default behavior. That your regex works in Kodos but not Python might mean you're writing a Kodus regex instead of a Python regex. > I'm writing a little program that scans the webpage of an arbitrary > application and gets the newest version advertised on the page. Firstly, most of the code you show is irrelevant to the problem. Please simplify it to the shortest, most simple example you can give. That would be a simplified piece of text (not the entire web page!), the regex, and the failed attempt to use it. The rest of your code is just noise for the purposes of solving this problem. Secondly, you probably should use a proper HTML parser, rather than a regex. Resist the temptation to use regexes to rip out bits of text from HTML, it almost always goes wrong eventually. > I was able to make a regex that matches in my code, but it shouldn't: > http://x264.nl/x264/64bit/8bit_depth/revision.\n{1,3}[0-9]{4}.\n{1,3}/ x264.\n{1,3}.\n{1,3}.exe What makes you think it shouldn't match? By the way, you probably should escape the dots, otherwise it will match strings containing any arbitrary character, rather than *just* dots: http://x264Znl ...blah blah blah -- Steven -- http://mail.python.org/mailman/listinfo/python-list
