6.1 XML Data Source

With the explosive growth of the Internet, a number of new data format standards have emerged. A widely accepted format is XML. With its self-descriptive properties, and both human and machine-readable content, XML has transformed the way that information is exchanged.

Style Studio uses 'XQuery', a standard developed by W3C, for querying XML documents and other forms of hierarchical data. XQuery transforms the hierarchy into a flat tabular format to make it more conducive to reporting and analysis. The conditional expression syntax (see Appendix Appendix A:, Hierarchical Query Condition Expression Syntax) is based on SQL and is very easy to learn. The following sections provide a few examples of creating XML queries.
