>I'm trying to convert some xmls (get from a webservice) to cursors using 'xmltocursor' but in some of them (not all) i get the error 'unable to infer xml schema', i try with the class xmladapter without success, the xml seems to be ok. I need some ideas to solve this...

The XMLTOCURSOR() is designed to process simple XML created by CURSORTOXML() or similar to it. The XmlAdapter can process more complex XML but not any arbitrary ones. It also required XML schema in order to convert XML into VFP cursors.
