Thanks, that clarifies things. I did look in the online help but didn’t find any specific guidance on regular expressions beyond “Oxygen uses Perl regular expressions”. I think at least a brief topic on regular expression syntax would be helpful, with a pointer to more information elsewhere.

Hi Eliot,
The ? operator makes it a lazy match (first best match) instead of a greedy match (longest possible match). Without the ? operator the expression is greedy and will match a lot more content than expected.
You can use either (.|\n)*? or .*? with "dot matches all", but in either case the ? operator is the one that limits the search to the first best match.

That works. But here’s another question: why is the outer group with the ? operator required? I tried just (.|\n)*, which should match anything between my start and end strings, but it does not, where ((.|\n)*?) does.
Thanks,
E.
