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?
