If this optimizes in a repeat loop faster than my offset() repeat loop handler, and I'll bet it does, then I can use it for single extractions where there is only one possible instance of a tag-set in the text being searched.
Sounds promising. You can also match without knowing the tag expected, using backreferences:
put "asdf <Sometag>qwertasdsay</someTag> zxcv" into tStr put "(?i)<(\w+)>(.+)</\1>" into tRxp -- or put "(?i)<(\w+)>([^<>]+)</\1>" into tRxp get matchText(tStr, tRxp, tMatch1, tMatch2) put tMatch1, tMatch2 -- says -- Sometag,qwertasdsay
In that example the \1 refers to the 1st capture (tMatch1), and uses it later in the pattern.
There is something funny about all this. Several years ago someone tried to tell me about using Perl regEx to do what I was doing. I didn't think there was a way to do it in Director so I forgot about it. Now it comes back several years later and it does work better, in Rev.
Cool!
