[a-z0-9]+ will match a sequence of characters containing one or more of the set [a-z0-9].
If you want to match a line of characters that contains NOTHING BUT [a-z0-9] then you could use: ^[a-z0-9]+$ If you want to match a sequence of characters that must start with [a-z] and contain any number of [a-z0-9] thereafter, you could use the regex: [a-z][a-z0-9]* Is this what you were looking for? cheers David.
