How get parent element attribute and child value from XML in java?

Question

I have a XML file, for example:

<parent value="first">
  <child>Bill</child>
</parent>

I want to get at output: value=first,child=Bill That means I need attribute from parrent element and value from child element.

I tried to do something like this:

List<Str> obj = new ArrayList<Str>();
NodeList nList  = doc.getElementsByTagName("parent");
for (int i = 0; i < nList.getLength(); ++i) {
    Element attrElement = (Element) nList.item(i);
    NamedNodeMap map = attrElement.getAttributes();
       for (int j = 0; j < map.getLength(); j++) {
            Node attribute = map.item(j);
            Node eNode = nList.item(j);
            Element name = (Element) eNode;
            obj.add(new Str(attribute.getNodeValue(), name.getElementsByTagName("child").item(0).getTextContent()));
       }
    }

In result i have Str with "null" values.

Use like this

      List<String> obj = new ArrayList<String>();
      NodeList nList  = doc.getElementsByTagName("parent");
      for (int i = 0; i < nList.getLength(); ++i) {
          NamedNodeMap map = nList.item(i).getAttributes();
             for (int j = 0; j < map.getLength(); j++) {
                  Node attribute = map.item(j);
                  Node eNode = nList.item(i); // Use i value here that is the issue. 
                  Element name = (Element) eNode;
                  obj.add(new String("Value = "+attribute.getNodeValue() + ",Child=" + 
                      name.getElementsByTagName("child").item(0).getTextContent()));
             }
          }

Add one outer element,It works fine for multiple tags

<xml><parent value=first> 
    <child>Bill</child></parent> <parent value=second> <child>Steve</child>
</parent></xml>

Thank you. But there is a problem. I have more than one parent. Attribute changes, but child name stays like first. I wanted if <parent value="first"> <child>Bill</child> </parent> <parent value="second"> <child>Steve</child> </parent> And the result I get: 1) value=first,child=Bill 2) value=second,child=Bill but value=second,child=Steve should be.

I copied yours xml. In both cases I get "Child = Bill"
