TRegularExpressionValidator class

TRegularExpressionValidator validates whether the value of an associated
input component matches the pattern specified by a regular expression.

You can specify the regular expression by setting the {@link setRegularExpression RegularExpression}
property. Some commonly used regular expressions include:
<pre>

French Postal Code: \d{5}

Use a {@link TRequiredFieldValidator} to ensure the input is not empty.
