ProductsXMLSpyXSL ToolsXSLT Profiler

Altova XMLSpy® 2012 includes a powerful XSLT Profiler for optimizing your XSLT 1.0 and XSLT 2.0 code.

In addition to its XSLT debugger, XMLSpy includes an XSLT profiler for fully optimizing your XSLT code. The XSLT profiler monitors and records detailed metrics for each processing instruction executed during an XSLT transformation, helping you identify and eliminate bottlenecks quickly. The XMLSpy XSLT profiler even supports profiling stylesheets that contain program code in Java, C#, JavaScript, or VBScript.

The XSLT profiler includes options for monitoring a transformation based on call graph or hit count.

When you transform a file in XMLSpy, the XSLT profiler displays metrics including hit count, duration, descendants’ duration, and XPath values. These are displayed for each XSL variable, parameter, and template. You can expand or collapse the results and view them in a list or tree view.

Clicking any element listed in the profiler window automatically opens its associated stylesheet and highlights the element, helping you track down performance bottlenecks with a single click.

Based on the information revealed by the XSLT profiler, you can immediately see which parts of your XSLT code are taking the most time to process and adjust them accordingly to fully optimize your XSLT stylesheets.

Charting Results

XMLSpy® 2012 will even generate a chart of the results, or a subset of the results, returned by the XSLT Profiler, giving you an instant, visual representation of your stylesheet's performance that you can save or share with other team members. As you optimize your stylesheet and profiler data changes, the chart is updated on-the-fly. You can choose which parameters to display in your chart, and pie, bar, line, and gauge styles are available.
