Yo all! ^_^

I'm trying to make a reg exp that will match a users inputed time. I want the RE to match a string like 8:00am or 12:00pm. My version of the RE is as follows:


But...of course...it dosen't work. It ALWAYS returns false. (I'm not great with RE... ) Can I get some help? And just to point out, I want the test to fail if it is not in the form (x)x:xx(am|pm).

Thanks a lot! ^_^

You can only use hyphens to say "everything between these two" in character sets ([ ]):
That's how I would do it.

Say, that's pretty cool. ^_^ The only problem that it runs into is that it accepts a time like 92341:00pm. Interestingly enough, it dosen't except 1:324324pm. I don't see any real difference in the re that casues the first part to not act as expected but the second part to be fine....strange...

Yo all! ^_^ You need to put some restrictions on the number of things that can match before the parser moves on and looks farther, dontchano.
