Subject: Help for extracting text with regexp.

Hi,

I'm having some trouble with the regexp :/

I'm messing up with the match, scan methods, I'm not sure wich one I
should use.

Here's what I'm trying to do :

I have a string that's an URL with get values :
Ex :
foo.bar/somePath/somepage.php?attr=value&theone=64646hs554&other=ddd

What I need is the value of the "theone" attribute.
This attribute may or may not be the last one in the string !

I don't know if it's possible to put the two cases in one regexp...

Here are my two regexp :

If it's not the last attribute
/session=(.*?)&/
If it's the last attribute
/session=(.*?)$/

What should I use next to extract the value ? scan or match ?

myString.scan(/session=(.*?)&/) ?
How can I handle the two situation ?

Thanks a lot for your help !

(Sorry for my english)

Pollop.
