Getting xml string data from element using XmlPullParser

Question

for example I have xml file:

 <names>
        <item value="Hello" />
        <item value="All" />
        <item value="This" />
        <item value="Data" />
 </names>

So I need to get all raw data from the given attribute (names):

    <item value="Hello" />
    <item value="All" />
    <item value="This" />
    <item value="Data" />

In a string format, so the data should be:

String data = "
<item value="Hello" />
<item value="All" />
<item value="This" />
<item value="Data" />
";

and I have a peace of code:

 int state = 0;
    do {
        try {
            state = parser.next();
        } catch (XmlPullParserException e1) {
            e1.printStackTrace();
        } catch (IOException e1) {
            e1.printStackTrace();
        }       
        if (state == XmlPullParser.START_TAG) {
            if (parser.getName().equals("names")) {

// here I need to get the data
// String data = ...

               break;
            }
        }
    } while(state != XmlPullParser.END_DOCUMENT);

so, how do I get data from xml element in string format?

I used DOM2XmlPullBuilder to convert XmlPullParser to a DOM, then convert the DOM to a string. The code looks something like this.

DOM2XmlPullBuilder dom2XmlPullBuilder = new DOM2XmlPullBuilder();
Element element = dom2XmlPullBuilder.parseSubTree(xmlPullParser);
convertNodeToString(element); // implement using a Transformer

I believe instead of where you have

if (parser.getName().equals("names")) {...

it should be something like this:

ArrayList<String> data=new ArrayList<String>();
....
....
if (parser.getName().equals("item")) {
   data.add(xpp.getAttributeValue(0));
}

I'm a beginner so I was just searching this information recently, luckily I found a helpful sample from commonsguy (which copied and ran fine without any change) - https://github.com/commonsguy/cw-android/tree/master/Resources/XML
