DOMEntityReference nodes in DOMAttr

[shilpa patil <sh...@hotmail.com>]

Hi,
   I am looking to generate an XML document using the DOMWriter and 
DOMDocument in
xerces 2.7. The element is of the form

         <Rule Id="&EURO;TEST" />

The code that I use to generate this is
    DOMElement *elemNode = doc.createElement ( X("Rule"));
    DOMAttr *attrNode = doc.createAttribute ( X("Id"));
    DOMText *textNode = doc.createTextNode ( X("TEST"));
    DOMEntityReference *entityRefNode = doc.createEntityReference 
(X("EURO"));

    if ( attrNode && textNode && entityRefNode ) {
           attrNode->appendChild ( entityRefNode );
           attrNode->appendChild ( textNode );
           elemNode->setAttributeNode ( attrNode );
    }

The issues are:
  1) The element is generated as <Rule Id="" />
  2) If I append the text node and then the entity reference node, the 
element
     is generated as <Rule Id="TEST" />
  3) If I append two text nodes, only the first node is serialized.

However, if I append the entity reference and the text node to an element 
node
(instead of an attribute node), it is serialized correctly (i.e.
<Id>&EURO;TEST</Id>).
Any help in adding entity reference nodes to an attribute node is greatly
appreciated.
Thx.

Hi Shilpa,
there is at least one bug in Xerces (when an attribute is constructed 
using multiple Text or EntityReference nodes, DOMAttr::getNodeValue 
will return the value of the first node only); as for the second 
problem, DOMWriter always uses getNodeValue() to print attributes, so 
it will not be able to print the entity references, but only their 
value. I think that DOMWriter should look at the "entities" feature 
in order to decide whether to use getNodeValue or walk the child 
nodes, even if the specs are vague on this topic.
A fix for these bugs will be available shortly.

Thanks,
Alberto
