Oracle XQuery Mapper is a graphical mapping tool that enables you to transform data between XML, non-XML, and Java data types, allowing you to integrate heterogeneous applications rapidly. For example, you can package data transformations in Oracle WebLogic Integration (WLI) as controls and reuse the controls in multiple business processes and applications. You can also use .xq files created in XQuery Mapper as resources in Oracle Service Bus.
The output of XQuery Mapper is a query in the XQuery language, which is defined by the World Wide Web Consortium (W3C). For more information about W3C and the XQuery language, see.
You can use XQuery Mapper to transform data between XML, non-XML, and Java data types. For example, XML data that is valid against one schema can be converted to XML that is valid against a different schema. The data can be based on XML schemas, Web Service Definition Language (WSDL) file, and Message Format Language (MFL) files.
When you select the Simple source type, you can transform standard schema types, such as
Date, to any other required target data format.
A data transformation can have multiple input types, but only one target type. For example, data can be transformed from two sources to one target, as shown in the following figure.
WLI supports data transformation for the following versions of XQuery:
When you open an XQuery 2002-compliant XQuery file, it opens automatically in the XQuery 2002 Transformation Editor, which has Source and Test views, but no Design view.
