Hi, There seems to be a different behaviour in the re module... Python: >>> import re >>> re.match("a[bcd]*b", "abcbd").group(1) Traceback (most recent call last): File "<stdin>", line 1, in ? IndexError: no such group Iron Python (Beta5): >>> import re >>> re.match("a[bcd]*b", "abcbd").group(1) '' -- Andrzej
