I know I really should be able to do this but my best effort is quite
awkward. What is a simple regex way to find and extract the string
"abc/def.x.y" from the following:

.... stuff <img alt="???" src="abc/def.x.y" /> ...other stuff

I can assume <img..../> is all on one line.

Thanks.

Yes and after:
----------------- test.rb ---------------------------
#!/usr/bin/env ruby

s = '... stuff <img alt="???" src="abc/def.x.y" /> ...other stuff'
r = regexp.new(/src="(.*?)"/)
if res = r.match(ligne)
print res[0], "\n"
print res[1]
end
-----------------------------------------------------

Where res[0] is the all match and res[1] is what you want the thing in
the group delimited by ()

s = "<img alt=\"???\" src=\"abc/def.x.y\" /> "
puts s
puts ( /<img.*src="(.*)" \/>/).match(s)[1]

result:
<img alt="???" src="abc/def.x.y" />
abc/def.x.y

' <img alt="???" src="abc/def.x.y" /> '[/src="(.*?)"/,1]

Well,,
I never heard of Hackett before,,, but if he got done unkindly on the
table,,, at least he would have known why...
If I had ever done anything against my GP's,, one might be able to
rationalise and say OK. fair doo's...
But I have no such luxury of having deserved it in any way,,,
the circumstances of my complaint are completely unacceptable and
intolerable...

I have been meaning to get back to this thread for a while but todal
asked a question about letters and i am having difficulty trying to
locate them...
