How to read XML file in android

Question

I want to read xml file which looks like the following ... I have stored it in assets folder with

<ImageList SpriteSheetName="hh_gmw01">
   <Image Name="gmw01"     x="0" y="0" width="1047" height="752"/>
   <Image Name="hht1l01"   x="388" y="269" width="34" height="36"/>
   <Image Name="hht1l02"   x="147" y="99" width="85" height="33"/>
</ImageList>

How do I get these values?

Answer 1

There is several ways to read a XML in Android. My first option is DocumentBuilder since do not create an API version restriction (is available since API Level 1).

An example from one of my projects:

public Document parseXML(InputSource source) {
    try {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        dbf.setNamespaceAware(false);
        dbf.setValidating(false);
        DocumentBuilder db = dbf.newDocumentBuilder();
        return db.parse(source);
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
 }

How do you read the file and access the document values after this, well, its pretty basic, just Google it.

            int imgNum = 0;

            Log.d("ImageList", "SpriteSheetName = " + xmlParser.getAttributeValue(null, "SpriteSheetName"));
            while (xmlParser.next() != XmlPullParser.END_TAG) {
                if (xmlParser.getEventType() != XmlPullParser.START_TAG) {
                    continue;
                }

                xmlParser.require(XmlPullParser.START_TAG, null, "Image");
                //. fetch nodes attributes here...
                Log.d("xmlNode", "img " + (++imgNum) +
                           " Name = " + xmlParser.getAttributeValue(null, "Name") +

                //................................
                xmlParser.nextTag();
                xmlParser.require(XmlPullParser.END_TAG, null, "Image");
            }


        } finally {
            xmlStream.close();
        }

    } catch (IOException e) {
        e.printStackTrace();
    }
    assetManager.close();
}
