Thanks Mary. I didn't realise that the 2001 version was mandatory for 1.4.0.
It's now looking like I'm just going to have to wait until the XML (supplied to me from a 3rd party) and all associated schemas are upgraded to the 2001 standard...

With Xerces version 1.4.0, you must use: xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; instead of xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"; in your XML file, and xmlns='http://www.w3.org/2001/XMLSchema' in your schema file. (Note the "2001" instead of "2000/10"). The next release of XMLSpy should generate the "2001" string. You should also set this additional feature in your code: parser.setFeature("http://apache.org/xml/features/validation/schema",true); Mary Ryan Space Telescope Science Institute ---------------------------------------------------------------------------- ------ "Heathcote, Guy" wrote: > > Hi all.
