Margaret,

Here is some sample VFP code to validate just using the MSXML parser. You must use MSXML version 4:

LOCAL oDoc AS MSXML2.DOMDocument
LOCAL oCache AS MSXML2.XMLSchemaCache
oDoc = NEWOBJECT('MSXML2.DOMDocument.4.0')
oCache = NEWOBJECT('MSXML2.XMLSchemaCache.4.0')
oCache.add('http://tempuri.org/ConfigSchema.xsd','c:\development\schemabuilder\ConfigSchema.xsd')
oDoc.async = .F.
oDoc.schemas = oCache
llOK = oDoc.load('schemaconfig.xml')
lcError = oDoc.validate()
IF lcError.errorCode <> 0
	? lcError.reason
ENDIF
