hey everybody,

I am trying to write a regular expression which accepts only alphanumeric

but the rule is ......it should not accept only alphabet or only numeric words

Examples:

word123--------> TRUE
123word--------->TRUE
word------------->FALSE (because only alphabet)
1234------------->FALSE (because only numeric)

Can any one help me in writing this.......

Thanks in advance

Well, it's pretty straightforward -- what have your tried so far?

yes...

Well. That depends.... Did you read up on regexes and figured out the solution yourself? Or did you simply got the solution from someone else? We can't really give you a hint on an "easier way" (assuming that there is one), if you don't understand this regex.

Hey thanks for your support,

Actually, I needed this regex somewhere in between my project.
As I had little time and as I am not an expert of regex, so tried to understand some basics of it.
I searched for the answer but could find only a close answer, so i modified it to suit my requirement.

My knowledge in regex is, I can only understand them but writing them on my own needs some more learning....

Once again thanks for your encouragement.
