Joel,
Sorry, I failed to mention that my input would also include more
ampersands "&" after the first one (ie. at the end of subsequent urls).
So rule one will always match, but it will include all of the url, the '&',
a whole bunch of crap in between, and the next url up to its '&'....!
You see the trouble?
I need to match up to "-", but only 'non-ampersand' characters:
non-ampersand: complement charset "&"
I have had success using this in little parse expressions, but sticking it
into
my main parse expression has proved to be very difficult for me.
Thanks for trying. :) Maybe today I'll figure it out.
(Yet again, a solution to a parse problem that wasn't explained fully to start
with...
dear oh dear...;-)
