Debugger for XQuery that uses Saxon

Question

Can anyone suggest a debugger for XQuery? I would prefer one that is either online or works within Eclipse, and I prefer something that uses Saxon. So far, all I've found is XQDT (which has little documentation and does not work with Saxon) and a few stand-alone commercial apps.

All I want to do is understand why my XQuery isn't selecting the elements I think it should. (My requirement for Saxon is because I've had bad experiences with these processors not meeting the same standard.)

Any suggestions? How are others testing their queries?

Answer 1

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

The only debuggers build so far in XQDT are for:

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

You can have our latest version from:

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

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

Answer 3

No Saxon, but I was able to get Eclipse and XQDT to work with the debugger. Just getting going though, so there could still be some lurking issues. http://richmacdonald.blogspot.com/2011/02/debug-xquery-in-eclipse-configuration.html
