Wes:
Unfortunately, the new string doesn't work at all. Also,, m.Groups[0].Value
still returns the string in quotes (using the original string you gave me).
I did try to figure out what that pattern is doing - whew! It uses a
character that isn't even documented in the doc I've been using - the "<"
char? I'm going by what's at:
http://msdn.microsoft.com/library/de...gexpsyntax.asp
At this point, this is mostly an intellectual exercise - I have it working
by trimming out the surrounding quotes. Just a little bit of a hack. If
you have something else for me to try, I'd love to try it. I used to be
competent with this stuff, in my old sed, awk, and lex days. But, it's been
a while. If you'd prefer to punt, that's fine, and thanks for all your help
so far.

from m.ToString(). That will actually return the Value of the first group
(m.Group[0].Value) which is defaultly the entire sub-string that the match
was found in. You can try m.Group[1].Value that will give you the string
without quotes.[color=blue]

with Trim. I think this may make your job a little easier (that is as long
as you don't try to figure out exactly what that regular expression is
doing, I still have trouble with it when I don't look at it for a while ;)[color=blue]
