Manipulating data with XSL

Summary:  What happens if you need to manipulate data in a database, but you can't create stored procedures? You pull the information, manipulate it, and put it back, that's what. One way to conveniently do that is to retrieve the data into XML structures and then use XSL to manipulate it. This tutorial teaches you to use XSLT to manipulate data that has been pulled from a database and then restore it to the database. Examples are in Java, but the principles apply in other languages.

XSLT data manipulation summary

Summary

This tutorial demonstrated an application that retrieves data from a database into a DOM Document object, then uses an XSL style sheet to transform the data into another DOM Document. The style sheet uses XSL variables, XPath expressions, and functions to simulate some of the operations that might be carried out by a database stored procedure. The application then inserts the newly transformed data inserted back into the database.
