XML and Transformation Datatypes

PowerCenter supports all XML datatypes specified in the W3C May 2, 2001 Recommendation. The following table lists the XML datatypes and compares them to the transformation datatypes in the XML Source Qualifier transformation. For more information about XML datatypes, see the W3C specifications for XML datatypes at http://www.w3.org/TR/xmlschema-2.

You can change the datatypes in XML definitions and in midstream XML transformations if you import an XML file to create the definition. You cannot change XML datatypes when you import them from an XML schema. You cannot change the transformation datatypes for XML sources within a mapping.

The following table describes the XML and corresponding transformation datatypes:
