Regular expression for hexadecimal string in python not working
hex, python, regex
Solution
I used the following :
pattern = re.compile(r'(\n--)([0-9A-F]+)(--)?', re.I | re.S | re.M)
and it worked fine. Thanks to all your contributions.
Problem
I have a regular expression to match strings like: --D2CBA65440D --77094A27E09 --77094A27E --770 --77094A27E09-- basically, it matches a hexadecimal string surrounded by one or more line breaks or white space, and has the prefix -- and may or may not have -- as suffix i use the following python code, and it works fine most of the time: ``` hexaPattern = "\s--[0-9a-fA-F]+[--]?\s" hex = re.search(hexaPattern, part) if hex: print "found a match" ``` this works for all of the above but it doesn't match --77094A27E09 in this block: ``` <div id="arrow2" class="headerLinksImg" style="display:block --77094A27E09 ;"> ``` but matches the same string in: ``` <input type="checkbox" name="checkbox" id="checkboxKG3" class --77094A27E09 Content-T="checkboxKG" value="KG3" /> ``` What am i doing wrong?
