Help in using regex in Validation.xml
Hi,
This question can be termed as an OT as it is related to regex. I have a
validation criteria which says:
a number cannot start with "000" which is 9 digits in length.
Can somebody help me in writing a regular expression for this?
Thank you

Posted by sr...@wachovia.com.
Actually, I managed to get the correct expression for the condition
^(?!000)\d{9}$
Seems to work!!!

RE: Help in using regex in Validation.xml
Ouch! You are correct. :-(
I was looking at this a little more and I thought it would be nice to be
able to do something like ^[001-999]\d{6}$ where the first three positions
must be in the range of 001 through 999 (effectively filtering out the 000
case). Unfortunately, the [] operator can not be used in this fashion.
I was not able to figure out how to properly represent this idea but I
would
be interested if some RegEx guru out there has any ideas.
Thanks,
-Rod

Not quite.
With the regex ^000\d{6}$, if you DON'T get a match, the input could be
any length and might not even be a number: after all, it isn't matching.
All this checks is the particular case where you have a 9-digit number
which starts with 000: any of the other possible problems aren't
addressed.

This won't actually work. The parentheses should be braces and if you
don't
supply the start ("^") and end ("$") delimiters you will match
nine-digit
patterns within larger patterns as well (which I assume you don't want).
The correct simple syntax is: ^000\d{6}$
In your code, if you DON'T get a match, you have a valid nine-digit
number
(i.e. a number that is nine digits in length and DOES NOT start with
"000").
If you DO match, you have an invalid item.

What exactly are the criteria?
If its only a nine digit number that cannot start with 000 then I
would look for a number which does start with 000
000\d(6)
if it matches you know it's wrong.
If the number of digits are variable, or you want to catch 00, 100
011, then it gets a little more difficult.

RE: Help in using regex in Validation.xml
Posted by sr...@wachovia.com.
I appologise for the incomplete information.
Let us assume that I address the length to be 9 and type to be digits
criteria then this expression seems to address the not condition.
Now, how do i use this expression in validation.xml, without actually
writing my custom validator?
Some pointers would be of great help.
