Dom parsing in android
<p>i have parsed xml using dom parser,but when the xml element contains no value it throws null pointer Exception.how to check this?...
here my code</p>

<pre><code>NodeList TrackName1 = fstElmnt2.getElementsByTagName("Artist_Name");    


                    Element TrackElement1 = (Element) TrackName1.item(0);

                    TrackName1 = TrackElement1.getChildNodes();
                     result=result+((Node) TrackName1.item(0)).getNodeValue()

                     String  Artistname=((Node)TrackName1.item(0)).getNodeValue();



                                            }
</code></pre>
