saywell Posted March 11, 2011 Share Posted March 11, 2011 Hi,I'm trying to pick out 6-digit numbers from a string.(\d{6,6}) works, but it includes numbers of more than 6 digits, and also 6-digit numbers with a prefix, neither of which do I want.Could one of you RegEx gurus point me in the right direction to limit the start to the beginning of a 'word' and the whole thing to match 6 and 6 only consecutive digits?I've tried playing with /b -- (\(\d{6}) but that gives a load of blank returns in between the correct ones, though it filters the numbers with a digit prefix OK.Regards,William Link to comment Share on other sites More sharing options...
Moderators Melba23 Posted March 11, 2011 Moderators Share Posted March 11, 2011 saywell, It is always easier if you can give a few samples with the required output. Otherwise we risk producing an SRE which does not do exactly what you want and we have to start all over again. As I age considerably each time I try to write one I would prefer to do it as little as possible.

saywell Posted March 11, 2011 Author Share Posted March 11, 2011 OK, it's the agenda from a medical meeting, which starts as a word doc [table] and is copied to a string as per the attached text file [anonymised]. I need to get all the stand-alone 6 digit numbers - excluding components of the YH-prefixed 8-digit number, or indeed any other numbers with a letter prefix, and any that aren't exactly 6 digits long. If I load the file into PCRE Toolkit and use (\(\d{6}) it gives all the correct matches, and no incorrect matches apart from null strings [which faut de mieux I could take out of the array using non regex techniques].

Moderators Melba23 Posted March 11, 2011 Moderators Share Posted March 11, 2011 saywell, This works for me: #include <Array.au3> $sText = FileRead("test.txt") $aArray = StringRegExp($sText, "\s(\d{6})\s", 3) _ArrayDisplay($aArray) Explanation: \s = any horizontal whitespace (\d{6}) = match any six digit sequence \s = any horizontal whitespace Does it work for you too? M23 P.S. Not as much as an extra grey hair - I must be getting better at SREs!
