xml转化为map

 public static Map Dom2Map(String xml) throws Exception{ 
    	Document doc = DocumentHelper.parseText(xml);
        Map map = new HashMap(); 
        if(doc == null) 
            return map; 
        Element root = doc.getRootElement(); 
        for (Iterator iterator = root.elementIterator(); iterator.hasNext();) { 
            Element e = (Element) iterator.next(); 
            List list = e.elements(); 
            map.put(e.getName(), e.getText()); 
        } 
        return map; 
    }
