in thread Two-dimensional match/regex?

I think the above won't work as such, because it might find false matches (e.g. where the second line isn't aligned with the first.)

But, I could find the first line and then generate a multi-line regex with the rest of the search string, using /m as you suggest: something like   /^.{$pos}$string1.*\n^.{$pos}$string2.*/m to make it search only at the right position...
(Apologies for dodgy regex, not tested and probably wrong).

thanks for the tip, I should have thought of that already!
