Debug an XSL Transformation
When you use the XSLT debugger to run a transformation you can control the process and inspect the state of the transformation using Enterprise Architect's debugger in combination with breakpoints. The XSLT Debugger provides a and various . You set breakpoints by clicking in the left margin of the stylesheet.
When a step completes or a breakpoint is encountered, the context of the transformation - including any parameters to template calls - can be viewed in the Locals window ('Execute > Windows > Local Variables'). You can also display the Call Stack ('Execute > Windows > Call Stack) to see how the current state of the transformation was reached.

The final icon in the toolbar provides the option of hiding or showing the '.xml source' tab in the view. You can use these buttons to repeat and control the debugging process.
