Question

I am using JDOM parser to parse a XML i created using feedrinse.

XML is available at: http://www.feedrinse.com/services/rinse/?rinsedurl=396ac3b0142bb6360003c8dbac4f8d47

My code is to parse every title,link,pubDate element and store them in a new XML which i am sending to front end. Here is my code:

String temp = "http://www.feedrinse.com/services/rinse/?rinsedurl=396ac3b0142bb6360003c8dbac4f8d47";
String XMLstr="<FEED>";

SAXBuilder builder = new SAXBuilder();
URL url= new URL(temp);
Document doc = null;                
 try{
    doc=builder.build(url);             
    Element root = doc.getRootElement();
    //List children = root.getChildren();
    List list = root.getChildren("item");
    XMLstr+="<children>"+list.size()+"</children>";
    for (int i = 0; i < list.size(); i++) {
           Element node = (Element) list.get(i);
           String title=node.getChildText("title").toString();
           XMLstr+="<title>"+title+"</title>";
           String link=node.getChildText("link").toString();
           XMLstr+="<link>"+link+"</link>";
           String desc=node.getChildText("description").toString();
           XMLstr+="<desc>"+desc+"</desc>";
           String pubDate=node.getChildText("pubDate").toString();
           XMLstr+="<pubDate>"+pubDate+"</pubDate>";           
        }
    }
catch(Exception e)
    {
    out.println(e);
    }
    XMLstr+="</FEED>";

However, it is not parsing correctly. At first it always show children size as 0. Please suggest what mistake i am doing and how can i rectify the same. Thanks.

Answer 1

The XML has the following structure

<rss>
  <channel>
    ...
    <item></item>
    <item></item>

E.g. Element root = doc.getRootElement() will return the rss element which does not have any item children.

EDIT: Try the following line

List list = root.getChild("channel").getChildren("item");
