Hi Alexander,

"Full hierarchical" is about an XML document structured in a non-regular way. Regular XML Documents have a limited nesting level of its elements. You can imagine a Regular XML Document as the one generated by the following line of VFP code:

CURSORTOXML("MyCursor", "lcXML")

The resulting XML document has a limited number of nested elements, basically something like:

<VFPData>
   <MyCursor>
      </MyField1>...</MyField1>
      </MyField2>...</MyField2>
      ...
      </MyFieldN>...</MyFieldN>
   </MyCursor>
</VFPData>

On the other hand, hierarchical XML have an undetermined number of nesting levels, which could not be understood by XMLTOCURSOR() and CURSORTOXML() functions.

About your question about performance, unfortunately I don't have these numbers.

HTH.
