To debug a stylesheet or XQuery document, follow this procedure:

  1. Open the source XML document and the XSLT/XQuery document.
  2. If you are in the Editor perspective, switch to the XSLT Debugger or XQuery Debugger perspective with one of the following actions:
    • Select Window > Open perspective > XSLT Debugger/XQuery Debugger or the XSLT Debugger/ XQuery Debugger button in the top-right corner of the interface.
    • Select Document > XML Document > Debug scenario or use the Debug scenario action on the toolbar.. This action initializes the Debugger perspective with the parameters of the transformation scenario. Any modification applied to the scenario parameters (the transformer engine, XSLT parameters, transformer extensions, etc.) will be saved back in the scenario when exiting from the Debugger perspective.
  3. Select the source XML document in the XML source selector of the Control toolbar. In the case of XQuery debugging, if your XQuery document has no implicit source, set the source selector value to NONE.
  4. Select the XSLT/XQuery document in the XSLT/XQuery selector of the Control toolbar.
  5. Set XSLT/XQuery parameters from the button available on the Control toolbar.
  6. Set one or more breakpoints.
  7. Step through the stylesheet using the following buttons available on the Control toolbar:
    • Step into
    • Step over
    • Step out
    • Run
    • Run to cursor
    • Run to end
    • Pause
    • Stop
  8. Examine the information in the information views to find the bug in the transformation process.
