Parsing unknown xml tags

Question

Hi
When the tags are known for xml document
a NodeList could be created and then the Tganame and TagNameValue could be found like so                NodeList nl_t  = elem.getElementsByTagName("type");
               NodeList nl_av = elem.getElementsByTagName("roomsAvailable");
               NodeList nl_pr = elem.getElementsByTagName("price");
                                //  get the element <type> and print 
                             type = (Element)nl_t.item(i);
                              tagname = type.getTagName();
                          node = (Node)nl_t.item(i);
                          nodeName = node.getNodeName();
                              tagnameValue = node.getChildNodes().item(0).getNodeValue() ;
                          // insert item into the vector
                          bb_Vector.add(tagnameValue);
                          System.out.println(  tagname.toString()+"   --->  : " 
                                                    + tagnameValue.toString() +"\n");                   
                             ///    XXXXXXXXXXXXXXX /////
                             //  get the element <price> and print its price
                              price = (Element)nl_pr.item(i);
                              tagname = price.getTagName();
                          node = (Node)nl_pr.item(i);
                          nodeName = node.getNodeName();
                              tagnameValue = node.getChildNodes().item(0).getNodeValue() ;
                          // insert item into the vector
                          bb_Vector.add(tagnameValue);
                          System.out.println(  tagname.toString()+"   --->  : " 
                                                    + tagnameValue.toString() +"\n");                   
  ///  Note the above isjust a  portion of the codeNow I have an xml document and I dont know any of the tags , and I need to scan it and print out all the TagNames and their valuse .
Could someone please help
Thanks

Here's a start:
node = document.getDocumentElement(); //get root node
//traverse document elements beginning from current root node:
            NodeList nodeList = node.getChildNodes();
            int count = nodeList.getLength();
            for (int i = 0; i < count; i++) { //for all children
                Node child = nodeList.item(i);
                if (child != null) { //just to be sure ...
                    String name = child.getNodeName();
                    int type = child.getNodeType();
                    //decoding:
                    switch (type) {
                    case Node.ELEMENT_NODE:
                        Element element = (Element) child;
...
