FACT(s) (Environment):
Progress 9.1D
SYMPTOM(s):
X-NODEREF or X-DOCUMENT APPEND-CHILD got an error: A node was inserted where it doesn't belong (9082)
CAUSE:
INITIALIZE-DOCUMENT-TYPE creates a document with a root node. Since XML can only have 1 root node, you cannot do an APPEND-CHILD on the document, unless it is a COMMENT node or PI node.
FIX:
Get the root node by calling GET-DOCUMENT-ELEMENT on the hDocument handle and then appending it to the children, as shown in this example:
DEF VAR hDocument AS HANDLE.
DEF VAR hOrder AS HANDLE.
DEF VAR hRoot AS HANDLE.
CREATE X-DOCUMENT hDocument.
CREATE X-NODEREF hRoot.
CREATE X-NODEREF hOrder.
hDocument:INITIALIZE-DOCUMENT-TYPE("" /*namespaceURI*/,
"EXAMPLE" /*rootNodeName*/,
"" /*publicId*/,
"http://mydtd_for_myxmldoc.dtd" /*systemId*/ ).
hDocument:GET-DOCUMENT-ELEMENT(hRoot).
hDocument:CREATE-NODE(hOrder, "ORDER", "ELEMENT").
hRoot:APPEND-CHILD(hOrder).
