The Stylus Studio XSLT debugger is a powerful XSLT tool for finding and eliminating XSLT errors, simplifying XSLT stylesheet development and improving the overall quality of your XSLT applications. The XSLT debugger gives you complete visibility and control over every step of the the XML transformation process, and it's the only XSLT tool to support cross-XSLT-processor, cross-language XSLT debugging - meaning you can perfectly replicate whatever XSLT stylesheet errors that you are experiencing regardless of what XSLT processsor you are using (for example: Saxon, MSXML, Microsoft System.XML, Apache Xalan, etc.). This standards-based approach to XSLT debugging is substantially much more helpful than the approach taken by other XML tools vendors, who provide XSLT debuggers that rely on their own proprietary XSLT processors and often result in compatibility issues or other hidden surprises when it comes to deploying your XSLT. Some of the other highlights of the Stylus Studio XSLT Debugger include:

• Set and Toggle XSLT Breakpoints
• Step-in, Step-out, and Step-over XSLT Stylesheets (Just like the Microsoft VC++ debugger)
• Dynamically Inspect XSLT Variables
• Set Watches on XSLT Variables or XPath Expressions
• View the XSLT Template Stack
• XSLT Template Stack Window
• Debug EXSLT Extension Functions using the integrated Java IDE
• Integrated XSLT Output Window
• Configure and Save XSLT Debugging Settings
