Sorry, I don't understand the question.

First you say "contain three number" but then you say "not more than one". Which is it??? 3 or 1???

Maybe give some examples of what is okay and what is not? That would be better.

yeah. I mean this regular expression must have three numberic in it.

and This regular expression appear not more than one.
This three numberic is a whole, appear or disappear?

Could u understand me?

Code:

123
234456789908

The regular expression will told me.
123
234
456
789
908

is Matched.

Ugh. I don't know. I'm not sure I could write a single regular expression to do that. Even it if it is possible, it would be very very hard. Harder than I can do.

Sorry.
