Validators

Validators

A validator component confirms that its input conforms to a condition. You can use validators to check input for maximum or minimum string lengths or numeric values, conformance with expressions, or many other conditions. You can apply multiple validators to the same input.
If the input does not conform to the condition, the validator triggers a notification. A
NotificationHandler
component can process the notification. For example, if you use validators in a Parser, a
NotificationHandler
can insert a warning message in the Parser output. For more information, see Notifications.
You can insert validators in locations such as the
validators
property of a
Content
anchor or
Map
action. The validators enable you to warn if the input is invalid, without necessarily failing the
Content
or
Map
.
In addition to the validators described in this chapter, you can validate data against a set of user-defined rules and generate an XML validation report. For more information, see ValidateValue.
