  node->children should be a text node with

        "

      "

   in it, the node->children->next should be the element node node2
and node->children->next->next should contain

                                "

 "

   as per your indentation. All spaces are significant in XML.

  There is no notion in XML of parsing "fragment of a document", it's defined
only in terms of parsing a full document.

  Parse errors in XML are *fatal*, proces MUST stop there if you find one.

  I'm apparently too jet-lag to fully understand what you are doing here,
sorry !
