Alaphanumeric variables

Toasty

I know how to do the ([A-Z]) and ([0-9]) set ups, how do I go about making it so it reads a-z and 0-9 for each character position? Like a "default alphanumeric" reader?
Example:
http://www.mysite.com/1e5df8b2... (MD5 Checksum)
How would I make it read the whole thing...If I use ([A-Z]+) I only get letters...etc

You need to use [A-z0-9]+ this tells the method to search for both upper and lower case letters, and numbers.

Abyss has a "Case-Sensitive" selection that I usually use (since the case isn't really going to play a factor in what I'm doing).
Thanks for the help with that! I'm sure it'll come in handy for other things too!

You could also use [\d\w] - it would allow alphabet letters (upper and lower case), digits, and the underscore.

Since certain character classes are used often, a series of shorthand character classes are available. \d is short for [0-9].
\w stands for "word character", usually [A-Za-z0-9_]. Notice the inclusion of the underscore and digits.
