How to get all content of an element node in xml

elias_huang

I got a node after locating, and there are other nodes under this node. I now want to take out the xml fragment of this node, that is, the string fragment of this node in the xml document. How to do it better?

String fragment?
What xml parser do you use to do it.
You can parse everything out of this node and then organize it backwards into strings

Do you use DOM JDOM SAX or DOM4J?
Here is the DOM4J
         try {
          SAXReader reader = new SAXReader ();
          Document document = reader.read ("Demo.txt");
          Element root = document.getRootElement ();
           for (Iterator node = root.elementIterator (); node.hasNext ();) {

               // CompanyBean a = new CompanyBean ();

          Element element = (Element) node.next ();
          Attribute attribute = (Attribute) element.attribute ("value");
          a.setBirthday (element.elementText ("birthday"));
          a.setDepartment ((String) attribute.getData ());
          a.setName (element.elementText ("name"));
          a.setSalary (element.elementText ("salary"));
          list.add (a);
        }


        } catch (Exception e) {System.out.println (e.getMessage ());}

The above is very good.
