It's better to use TRY...ENDTRY instead of changing global error handler. In addition, it wouldn't work if put in a class with it's own error handler.

>You may need to use MSXMLDOM.Document (it as a "validated" property).
>Here's some sample script:

>PROCEDURE SET_DOMObject
>lcErrorHandler=ON('error')
>ON ERROR oXML=.NULL.
>oXML=CREATEOBJECT("MSXML2.DOMDocument.4.0") &&Try an implicit connect to 4.0
>ON ERROR &lcErrorHandler
>IF ISNULL(oXML) && Can't get 4.0
>   oXML=CREATEOBJECT("MSXML.DOMDocument") && Generic
>ENDIF
>oXML.async=.f.
>*oXMl.preserveWhiteSpace=.f.
>oXML.setProperty("SelectionLanguage","XPath")
>ENDPROC &&SET_DOMObject

>We also have MSXML2.XMLSchemaCache.3.0 to work specifically with schemas. Two ways to assure XSD: 1) The DOMDocument will validate as true when the XML is lioaded. 2) You will see the XSD information [nodes] added to the DOM afer it is loaded.
