So I did make it work but feel free to pitch in and tell me if this is
efficient or proper way.. I'm getting results fine with this
*try* {
DocumentBuilderFactory factory = DocumentBuilderFactory.*newInstance*();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(feedURL);
doc.getDocumentElement().normalize();
// get xml document root element
Element root = doc.getDocumentElement();
// get node list of all elements with tag name item
NodeList items = root.getElementsByTagName("Song");
ArrayList<String[]> musicSet = *new* ArrayList<String[]>();
*for* (*int* i = 0; i < items.getLength(); i++) {
Node itemNode = items.item(i);
*if* (itemNode.getNodeType() == Node.ELEMENT_NODE) {
Element itemsAsElement = (Element) itemNode;
Node _musicid=(Node) itemsAsElement.getElementsByTagName("musicid").item(
0).getChildNodes().item(0);
Node _asin=(Node) itemsAsElement.getElementsByTagName("ASIN").item(0).
getChildNodes().item(0);
Node _songname=(Node) itemsAsElement.getElementsByTagName("songname").item
(0).getChildNodes().item(0);
Node _albumname=(Node) itemsAsElement.getElementsByTagName("albumname").
item(0).getChildNodes().item(0);
Node _albumurl=(Node) itemsAsElement.getElementsByTagName("albumurl").item
(0).getChildNodes().item(0);
Node _albuminfo=(Node) itemsAsElement.getElementsByTagName("albuminfo").
item(0).getChildNodes().item(0);
Node _cover=(Node) itemsAsElement.getElementsByTagName("cover").item(0).
getChildNodes().item(0);
Node _isfree=(Node) itemsAsElement.getElementsByTagName("isfree").item(0).
getChildNodes().item(0);
Node _ringurl=(Node) itemsAsElement.getElementsByTagName("ringurl").item(0
).getChildNodes().item(0);
Node _songurl=(Node) itemsAsElement.getElementsByTagName("songurl").item(0
).getChildNodes().item(0);
String musicid=_musicid==*null* ? "N/A" : _musicid.getNodeValue();
String asin=_asin==*null* ? "N/A" : _asin.getNodeValue();
String songname=_songname==*null* ? "N/A" : _songname.getNodeValue();
String albumname=_albumname==*null* ? "N/A" : _albumname.getNodeValue();
String albumurl=_albumurl==*null* ? "N/A" : _albumurl.getNodeValue();
String albuminfo=_albuminfo==*null* ? "N/A" : _albuminfo.getNodeValue();
String cover=_cover==*null* ? "N/A" : _cover.getNodeValue();
String isfree=_isfree==*null* ? "N/A" : _isfree.getNodeValue();
String ringurl=_ringurl==*null* ? "N/A" : _ringurl.getNodeValue();
String songurl=_songurl==*null* ? "N/A" : _songurl.getNodeValue();
itemData = *new* String[] { musicid, asin, songname, albumname, albumurl,
albuminfo, cover, isfree, ringurl, songurl };
musicSet.add(itemData);
}
}
*return* musicSet;
