XSLT and XQuery Debugger
The XSLT/XQuery Debugger enables you to debug XSLT stylesheets and XQuery documents. It presents simultaneous views of the XSLT/XQuery document, the source XML/JSON document, and the output document. You can go step-by-step through the XSLT/XQuery document to see what output is generated at each step. At each step, the corresponding positions in the source XML/JSON document, the XSLT/XQuery document, and the output document are highlighted, and debugging information is displayed in ancillary windows of the debugger.
This section describes how to work with XSLT/XQuery Debugger and is organized into the following topics:
