hi,

that code should work (though i have not tested it) to retrieve 
namespaces declared in current element:

 for (int i = getNamespaceCount(getDepth ())-1; i >= getNamespaceCount(getDepth ()-1)-1; i--) {
           System.out.println(parser.getNamespacePrefix(i),parser.getNamespaceUri(i));
 }

the key to understand this is to realize that getNamespaceCount() 
function returns index into namespace uri and prefix tables 
(getNamespacePrefix/Uri(i) returns element in table at index i) for 
_any_ given depth so you can see what namespaces uris/prefixes declared 
between any depth levels in your case between current element 
(getDepth()) and its parent (getDepth()-1).
