You could have a list of all opened elements from the root to the innermost. To keep such a list, you append the name of the element to this stack at the end of startElement() and pop it off at the end of endElement(). In this way you have acces to the path of the current parser position. In order to differentiate between character data in Id and in Id/Id, you just have to iterate at the last elements of the list.
