wrong id for property current-element-node

           Summary: wrong id for property current-element-node
           Product: Xerces2-J
           Version: 2.0.0
          Platform: All

            Status: NEW
          Severity: Major
          Priority: Other

Hi,

According to Xerces documentation, id for current-element-node property should 
be : 

      http://apache.org/xml/properties/dom/current-element-node


The following code tries to get the current element, but raises an unexpected 
SAXNotRecognizedException :

if (parser != null) {
  Object o = null;
  try {
    o = parser.getProperty("http://apache.org/xml/properties/dom/current-
element-node");
  } catch (SAXException e) {
    // error handling
  }


Looking at DOMParser.java, we can see that getProperty(String propertyId) first 
check is to compare the propertyId string to CURRENT_ELEMENT_NODE :

  if (propertyId.equals(CURRENT_ELEMENT_NODE)) {
    ...
  }

but CURRENT_ELEMENT_NODE is sadly initialized to an incorrect value in 
AbstractDOMParser.java : 

  protected static final String  CURRENT_ELEMENT_NODE=
        Constants.XERCES_FEATURE_PREFIX + 
        Constants.CURRENT_ELEMENT_NODE_PROPERTY;

(where XERCES_FEATURE_PREFIX should be corrected to XERCES_PROPERTY_PREFIX).


  
Thus, a basic workaround to get a correct behaviour is, in my application, to 
query : 
  o = parser.getProperty(Constants.XERCES_FEATURE_PREFIX + 
Constants.CURRENT_ELEMENT_NODE_PROPERTY);


By the way, why wouldn't you give a public access to the handy constant 
AbstractDOMParser.CURRENT_ELEMENT_NODE (and to its similar brothers) ?

Regards. 

Patrick
