[xml] xpath and the document order

["Oleg A. Paraschenko" <olpa xmlhack ru>]

  Hello,

  as I understand, the function "xmlXPathEvalExpression" doesn't have to
return nodes in the document order. So here are questions.

1) Could you show an example of XML and XPath, for which
   "xmlXPathEvalExpression" returns nodes not in the document order?

2) What should be used for sorting a set of nodes:

"xmlXPathNodeSetSort" from "xpath.c" from libxml2, or
"xsltDocumentSortFunction" from "xsltutils.c" from libxslt?

  The only difference I found is a sort algorithm (Shell's sort vs
bubble (?) sort).


Regards,
