Input transformation rules perform any pre-processing of XML issued from the driver to the DirXML engine. This is a good place to perform data format mapping, for example changing a 15.2.1965 format for a birth date to a 2/15/65 format.
The input transformation rules are applied before the schema mapping transformation so the names of the attributes and classes are in the application's name space.
The style sheet can also be used for the following:
There are no required transformations that an input transformation style sheet must perform.
The input transformation rule is stored in a DirXML-StyleSheet object and is linked to the driver through the DirXML-InputTransform attribute of the driver's DirXML-Driver object.
