A serializer or mapper checks that its input is valid according to the XML schema. There are two validation modes:

To define the validation level, assign the

validate_source_document

property of the

Serializer

or

Mapper

component.

If you use the strict mode, a validation error causes the serializer or mapper to fail. The

Events

view displays the errors.

If you use the partial mode, the transformation might proceed despite certain validation errors. For example, if there are more occurrences of an element than the schema permits, a serializer typically ignores the excess elements and processes the valid ones, and it writes a warning in the event log. Similarly, it might ignore an element containing an invalid data type.

The Script uses the Xerces C XML Parser, version 3.1, to perform validation.
