Hi,

I have a validation criteria which says:

a number cannot start with "000" which is 9 digits in length. And it needs to be in one expression.

Can somebody help me in writing a regular expression for this?

Thank you

^(?!000)\d{9}$

This is not working...

do u care to explain what exactly is happening when u r trying the offered code?

Okay,, I appologise for a very short and insignificant message earlier.  I am trying to apply the pattern in a struts validation framework (JAVA Based) because of absence of a unix falavored platform. I used this expresssion by a javascript validator at http://tools.netshiftmedia.com/regexlibrary/# to validate the expression. But it shows the numbers like "123456789" are also invalid. May be i am trying a wrong validator. Can you suggest some other validator where this thing works (if it)?

just tried it OK [got match] in the same tester  http://tools.netshiftmedia.com/regexlibrary/ for input

123456789

u probably introduced one extra white space when copy/pasted the regex into the tester's textbox. I typed it there ;=). Make sure there's no space after

 ^(?!000)\d{9}$

 and try again.

It works, Thanks for the help.
