| * A validator for regular expressions. | |
| * | |
| * This validator will return true, when the passed value *matches* the | |
| * regular expression. | |
| * | |
| * ## This class replaces the former class MaskValidator ## | |
| * | |
| * If you do want to test if the value does *not* match an expression, | |
| * you can use the MatchValidator class instead. | |

| * | |
| * <code> | |
| * <column name="email" type="VARCHAR" size="128" required="true" /> | |
| * <validator column="username"> | |
| * <!-- allow strings that match the email adress pattern --> | |
| * <rule | |
| * name="match" | |
| * value="/^([a-zA-Z0-9])+([\.a-zA-Z0-9_-])*@([a-zA-Z0-9])+(\.[a-zA-Z0-9_-]+)+$/" | |
| * message="Please enter a valid email address." /> | |
