Re: [libreoffice-users] REGEX difficulty

What flavour of regex are we talking about?
Can you show us how you get three matches here.
I can only see that there will be one match, 29, 79 or 97.
Furthermore, if you intend to use this as a "lookahead", there is something
missing in the regex, the prefix that shall be matched if it is followed by
one of these numbers, and in this case, only 29 will make that prefix match.
If you provide the help description of the parameters to REGEX() I'm sure
we can find an explanation of its behaviour.
