regex question

All-
Is there a way to tell matchChunk() not to be greedy?
I've got a regular expression stumper here. I'm using regex with the
matchChunk() function and I've BZed a problem with it. Now I'm looking
for a workaround that still manages to use matchChunk().
MatchChunk() is apparently implementing regex's "greedy" mode, so a
call to matchChunk() returns everything between the first <B> tag and
the *last* </B> tag. So...
put "<B>hello, bucko</B> this is a <B>test</B>"
matchChunk(tRawText, "(?s)<B>(.+)</B>", tPos, tEnd)
returns "hello, bucko</B> this is a <B>test"
What I'd like to return is just "hello, bucko". Is there some regex
incantation that will do this for me? I can't seem to come up with it.
