Regex Help

[G]

Hello,

I have a REGEX validator which checks for DIGITS ONLY, 10 or 11 digits in
length. The pattern is:#

^\d{10,11}$

I would like to enhance this pattern so in addition to only digits, and
string must be 10 or 11 characters in length, - I would like the first
character to be a 0, and the second character must NEVER be a 0.

Matches:
0100000000
01234567890
0101010101

Non Matches:
1000000000
0010000000
1010101010

Any regex pro's here able to assist?

Kind Regards,

Gary.

^0(?!0)\d{8,9}$

That would be:

^0(?!0)\d{9,10}$

as the look-ahead doesn't consume the character. :)

Here's another way of writing it, perhaps a bit more straight forward:

^0[1-9]\d{8,9}$
