Hi,
I am unable to read my rss file's all chid elements
the structure of xml is like

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
<channel>
<channeltitle>fgdfg</channeltitle>
<channellink>dfgdf</channellink>
<channeldescription>gdfgdfg</channeldescription>
<item>
<item1>
<itemtitle1>gdfgdf</itemtitle1>
<itemlink1>gdfgdfgd</itemlink1>
<itemdescription1>gdfgdfg</itemdescription1>
</item1>
<item2>
<itemtitle2>fgdfg</itemtitle2>
<itemlink2>dfgdfg</itemlink2>
<itemdescription2>dfg</itemdescription2>
</item2>
</item>
</channel>
</rss>

I think you would have an easier time dealing with multiple items if you
had a single "item" element type with an attribute giving the item
number, if you need it.

here no of items can be any.
so the respective code is here.

import="org.jdom.*, org.jdom.input.*, org.jdom.output.*"
//main code
try {
SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(new File("c:\\rsshandler.xml"));
XMLOutputter fmt = new XMLOutputter();
fmt.output(doc, System.out);
// Get the root element
Element root = doc.getRootElement();
root.getName();//rss
List servlets = root.getChildren("channel");//channel

This asks for children of the root with name "channel". Try asking for
all children, root.getChildren().

Iterator itr = servlets.iterator();
while (itr.hasNext()) {
Element servlet = (Element) itr.next();
out.print("\t" + servlet.getChild("channeltitle")
.getText() +
" for " + servlet.getChild("channellink")
.getText()+
"and"+ servlet.getChild("channeldescription").getText());
}

} catch (Exception e) {
e.printStackTrace();
}
till here its ok. But
i am not able to read items. any one can do anything.
i tried with many other options but haven't got the exact structure.
