But assuming that the page will not change a lot its structure you could use a regular expression like this: expr = re.compile(r'name\s*=\s*"LastUpdated"\s+value\s*=\s*"(.*?)"', re.IGNORECASE) number = expr.search(text).group(1) (Handling of "not found" and "duplicate" cases is left as an exercise for the reader) Note that <input value="1178658863" type="hidden" name="LastUpdated" /> is as valid as your html, but won't match the expression. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
