Combine regular Expressions

Question

I need help to combine the following two regular expressions:

1.ValidationExpression="[^\s]{5,12}" : (5-12 non-blank characters)
2.ValidationExpression="^[0-9]+$"    : (Only integers)

Thanks.

Answer 1

I fear I might be missing something but won't this do it

^[0-9]{5,12}$

Answer 2

You could only allow 5-12 numbers like this:

ValidationExpression="^\d{5,12}$"

\d stands for [0-9]
