A debugger for XQuery that uses Saxon

Question

Can anyone suggest a debugger for XQuery? I would prefer it to be online or work in Eclipse, and I prefer what Saxon uses. So far, all I have found is XQDT (which has little documentation and does not work with Saxon) and several standalone commercial applications.

All I want to do is understand why my XQuery does not select the elements that I think should. (My requirement for Saxon is that I had a bad impression that these processors did not conform to the same standard.)

Any suggestions? How do others test their queries?

Answer 1

Currently, XQDT only supports execution (no debugging) with the Saxon XQuery processor.

The only debuggers created so far in XQDT are for:

• Zorba XQuery Processor: http://www.zorba-xquery.com/
• Sausalito XQuery framework web application: http://www.28msec.com/

You may have our latest version:

• Eclipse update site: http://download.eclipse.org/webtools/incubator/repository/xquery/milestones/ (updated every 6 weeks)
• or download the already packaged Sausalito Tools: http://www.28msec.com/download/download_sausalito (updated every 2 weeks)

oXygen offers an XQuery debugger that can be used with both SaxonEE and the MarkLogic XML database:

Answer 3

No Saxon, but I was able to get Eclipse and XQDT to work with the debugger. Everything just goes, so there may still be some hidden problems. http://richmacdonald.blogspot.com/2011/02/debug-xquery-in-eclipse-configuration.html
