Yes, I did update my message with the quote from VFP help. Thank you.

>>UPDATE: From VFP Help:

>>CURSORTOXML( ) output adheres to the cursor index order, SET FIELDS TO, and current filter settings. However, it does not preserve the cursor location. After the calling CURSORTOXML( ), if all records are output, the cursor record pointer reports EOF. If not all records are output, it points to the last record output to XML.

>>So it confirms that the record pointer moves to EOF(). I suppose that my "solution" of moving the pointer to the TOP makes sense.
