Altova RaptorXML Server 2025

The Visual Basic example below does the following:

•Set up and initialize the RaptorXML .NET object

•Validate an XML file

•Perform an XSLT transformation, return the result as a string

•Process an XQuery document, save the result in a file

•Set up the execution sequence of the code and its entry point

Option Explicit On
