problem with "mask" of validation

[Deepa Khetan <de...@gmail.com>]

Hi,

Have a problem with validation framework. In the "mask" attribute we specify
which characters are allowed as input. Is there any way in which we can
specify which characters are not allowed as input?

Regards,
Deepa

You should be able to accomplish this with altering the regular
expression. If you are having troubles with regular expressions,
search google for perl regular expressions there are a ton of examples
out there.

eg:
This states that the match should be from beginning to end of string
matching 0-9, a-z or A-Z and that is all, no special characters. The *
means zero or more of these characters.

<var-value>^[0-9a-zA-Z]*$</var-value>

With a regular expression you can say not any of the above by putting
in a character in the front of the character class.
<var-value>^[^0-9a-zA-Z]*$</var-value>


This is untested, but I have used this type of matching in the past.
