XSLT can be more flexible than the average database in the following circumstances:

• It is capable of applying complex queries on XML databases containing:
  • Irregular Data
  • Searching based on position
  • Recursive structures
  • Structures with complex matching requirements
• We have only touched the surface of what is possible
• Quite similar to XQuery (the SQL of XML Databases)
• Saxon V9 supports both XSLT and XQuery
• Tailoring output for different environments is another major use of XSLT
• XSLT is what makes XML useful and important
