  Available as:
     xmlChar * xmlGetNodePath(xmlNodePtr node);

in libxml2 (http://xmlsoft.org/)
   http://xmlsoft.org/html/libxml-tree.html#XMLGETNODEPATH

Note of course that there isn't "the" XPath string to select that node
there is an infinity of those. 2 implementation could return different
path and both be right.
