Hi Terry,

IMHO, XML2.Document can load XML without XSD. If you have any problem , LoadXML() or Load() return .F., You can set property ValidateOnParse=.F.
From MSDN:
Boolean. The property is read/write. If True, it validates during parsing. If False, it parses only for well-formed XML. The default is True.

XML2.Document cannot load XML without DTD.

DTD - you need for loading
XSD - you need not for loading

How work XMLAdapter I Don't know, because I don't need it. I use MS XMLDOM for parsing Jabber XML stream.

Hmm. IMHO XML engines load root records from XML and analysing they. If found any informations about DTD or XSD, try load it.



Terry, is big difference between XMLDOM and implementation in XMLDOM in IE or another SW.

>>>Well I'll be @!#*. You are right. I've been running in circles trying to figure out how to write schemas and dtd's and never thought to try the xmltocursor on this piece of data. The sample of course is only part of a much more complex file that has data in mixed forms like that shown (mixed between <>) and also other parts where the data is separated into discrete elements like:
>>>
>>>

>>><schedule time=1 display=45 program=xx76578 />
>>><data>
>>><data1>xxx</data1>
>>><data2>XXX</data2>
>>></data>
>>>

>>>Can you give me some help on how to write a schema to deal with this? I'd prefer to do the whole job in VFP if I can.
