The XData Toolkit is an XML/XSLT transformation engine and Database Toolkit that uses many sources including MySQL, XML, RSS Feeds and Web Services.
This plugin has very helpful and extensive documentation - which all amount to nothing since I couldn't get the thing to work.
It would not accept a Mysql database as source initially - and when I did get it to finally accept my settings, it showed the wrong database - which is a bit bizarre.
As to the query - both hand-input & the so-called visual designer - neither worked or even allowed me to save the query.
I've wasted a good 3 hours on this piece of rubbish and have to ask whether the developer actually tested it before advertising its presence.
Tried several times to add MySQL data sources using known credentials & localhost, wouldn't do a thing when I pressed the test button, then wouldn't save anything. Tried several times. I can query the db using other tools as well as phpMyAdmin, but this plugin just wouldn't do a thing. Then when I deleted the plugin, it didn't clean up after itself and left all the xdata tables in the db.
