Introduction to the XQuery Mapper

Introduction to the XQuery Mapper, provides an overview of how to connect to query and aggregate XML sources in a powerful, standards-compliant way.

Introduction to XQuery Mapper covers the following topics in detail:

• Selecting XML data sources for an XML mapping project, including web service data and XML data
• Specifying the use of dynamic, Web service data for use in an advanced XML mapping project, in addition to an XML document
• Specifying a target XML Schema output format, and modifying the target XML Schema on the fly
• Specifying XQuery or custom functions to aggregate or manipulate data
• Defining and using custom data processing functions
• Visually specifying relationships between XML source document(s) to a target XML Schema
• Joining different XML data sources using an XQuery expression
• Creating advanced associations between repeating XML data elements using XQuery FLWR expressions (for, let where, and return) .
• Using visual, data processing function blocks in stylus studio to filter data based on conditions, or to specify looping
• Chaining together data processing function blocks, creating customized, advanced XML data transformation logic
• Previewing the output of an XQuery data mapping in Stylus Studio's XQuery output window
• Dynamically fetching web service data for use in XQuery transformation using the Web Service Call composer
• Understanding complex mapping relationships with Backmapping, which associates data in the Output Window with the line of XQuery code that generated that output
• Understanding Stylus Studio's 2-way, synchronized XQuery editing and mapping which allows you to create any XQuery expression, either manually using Stylus Studio's XQuery editor
