<$ShowURL=

I want to do a rex to just pull out "mj9ncegifsa" from the v=
everytime
How would I write it? Thanks in advance.

<rex ">>v\=\P=[^&;]*" $ShowURL>
would work. That will also skip any following query-string variables; e.g. for `
www.youtube.com/watch?v=mj9ncegifsa&foo=bar ' it would still pull out just the `v' value.
It works by looking for `v=' first (the `>>' anchor says start here first), then ignores that (the `\F'), then grabs all chars after that up until the next ampersand, semicolon, or end of string.
