Subject: newbie question: deleting all of a string's contents BEFORE a certain character

Hi,

I was trying to figure out how to take a string like this: "http://
www.youtube.com/watch?v=QMuClxuWdH8"
and removing everything before (and including) the "=", creating a new
string with just "QMuClxuWdH8".

At first I thought I would have to do something like:

url = "http://www.youtube.com/watch?v=QMuClxuWdH8"
rev_url = url.reverse
rev_chomped = rev_url.chomp("=")
code = rev_chomped.reverse

...which doesn't actually work of course and is ugly anyway. I have a
feeling I'll need to use regular expressions to do this, but I'm
really lost when it comes to regex. How could I do something like
this?


Thanks in advance!
