  Hi Peter,

 Well shouldn't be a PhD thesis problem :-)
The code sequence needed is :

  doc = xmlNewDoc("1.0");

  doc->root = parseSExpr(doc, "(foo (bar x y z) hu fu 'gnu)")

and parseSExpr is recursive , calling

  node = xmlNewDocNode(doc, NULL, name, NULL);

on the first item and

  xmlNewChild(node, NULL, childname, NULL)
