regular expression format. Help!

Hi,

I am trying to create a regular expression that has a few
requirements.

1. The data must all digits
2. The data must be 9 digits in length
3. The data cannot have 9 zero's.  ex: '000000000'

I have 2 issues:
I am having problems trying to check for a total of 9 zeros.
 My all
zero check does not work. It will fail if there is a zero
anywhere in
the data.  Not sure how to specify 9 zero total.

I read in an tutorial that I could use '&&'
intersection operation. So
I was trying to check for 9 digits AND not 9 zeros.  But
when I test
the expression, it seems it does not recognize the
intersection.

I can't figure it out.

Does any one know if this is possible to handle with regular
expressions or has another idea to handle the expressions?

Thanks!

u never mentioned in what environment u r working and what
flavor of
regex u r using. This would work in .NET:

^(?!0)d$

it matches on 123456789
but does not match 000000000

tested in the regex tool

Thanks so much for the help.  I am using Java, it works
wonderfully.
