Source: <prefix><content1><suffix1><prefix><content2><suffix2>
Engine: PCRE
RegEx1: (?<=<prefix>)(.*)(?=<suffix1>)
RegEx2: (?<=<prefix>)(.*)(?=<suffix2>)
Result1: <content1>
Result2: <content1><suffix1><prefix><content2>
The desired result for RegEx2 is just <content2> but it is obviously greedy. How do I make RegEx2 non-greedy and use only the last matching lookbehind?
[I hope I have translated this correctly from the NoteTab syntax. I don't do much RegEx coding. The <prefix>, <content> & <suffix> terms are just meant to represent arbitrary strings. Only the "<" in the "?<=" lookbehind command is significant.]
I suspect it is something simple but after too many hours of searching I'm giving up on solving it myself.
Thanks for the help

I just had the same problem. But in my case it was
That did what I wanted.
This expression will match anything that is a concatenation of characters between
<prefix>
and<suffix>
and doesn't contain the substring<prefix>
. (I think so. I'm not very good at regexp.)Put something greedy in front of it?
Since the greedy
(?:.*)
will gobble as much as it can, only the minimum will be matched by the rest of the pattern - effectively making the rest non-greedy.The non-greedy
.*?
might also work:I suggest you use:
This makes sure that there can be no
<prefix>
inside the match. The complete match result will be<content2>
