Thank Conrad... but I think the engine is the one that&#39;s wrong, coz what would then be the difference between ^\d{10} and ^\d{10,} ?<br><br><div class="gmail_quote">On 4 March 2010 00:27, Rad! <span dir="ltr">&lt;<a href="mailto:conradakunga@gmail.com">conradakunga@gmail.com</a>&gt;</span> wrote:<br>

Thats a handfull. Perl Regex (which I believe .NET implements) would be<br><br>/[0-9]{10}/ ... And to be absolutely sure : /[0-9]{10,10}/<br><br>Its also possible that the slight differences between these regex engines is the reason our good friend was pulling at his hairs.<br>

<br>
</div>the posix regex for 10 digits looks like this :<br>
[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]<br>
