RSS XML Parsing with XPath

[fiveironfrnzy80]

Hello all,

I have a method shown below that is failing at the point of the xpath evaluation constructor consisting of (expression, InputSource, qname) -

Node node = (Node) xpath.evaluate("//item", is, XPathConstants.NODE);

If I change it out and use the alternate constructor (expression, InputSource) that returns a String, then it works -

String node = xpath.evaluate("//item", is);

I just can't seem to get it to return the node, though...

I'm including the two difference versions of the method below, one that returns the Node (doesn't work) and one with the String(does work):

private Node getFeed(String urlToRssFeed, Context context)
    {
    	try
    	{
    		// setup the url
    		URL url = new URL(urlToRssFeed);
    		
			XPath xpath = XPathFactory.newInstance().newXPath();
			
			URLConnection con = url.openConnection();
			con.setConnectTimeout(15000);
			con.setReadTimeout(15000);
			InputSource is = new InputSource(con.getInputStream());
			
			Node node = (Node) xpath.evaluate("//item", is, XPathConstants.NODE);
			
			return node;
    	}
	    	catch (Exception ee)
    	{
    		Log.d("RyanDebug", ee.getMessage());
    		return null;
    	}
    }

private String getFeed(String urlToRssFeed, Context context)
    {
    	try
    	{
    		// setup the url
    		URL url = new URL(urlToRssFeed);
    		
			XPath xpath = XPathFactory.newInstance().newXPath();
			
			URLConnection con = url.openConnection();
			con.setConnectTimeout(15000);
			con.setReadTimeout(15000);
			InputSource is = new InputSource(con.getInputStream());
			
			String string = xpath.evaluate("//item", is);
			
			return string;
    	}
	    	catch (Exception ee)
    	{
    		Log.d("RyanDebug", ee.getMessage());
    		return null;
    	}
    }

Is the same data being returned each time through the connection?
What happens in the first case if you replace NODE with STRING (and change the cast to a String)?

What happens if you read the data returned in the connection stream and save it as a file, and use a FileInputStream from that instead (which is what I'd do to ensure a consistent test environment)?

Thank you for the reply!
Turns out that it was actually working, Eclipse just seems to be acting very oddly. During the debugging session, it would evaluate and then jump to the "return null;" in the exception catch. If you continue on from there, the program acts as if it evaluated "return string;" successfully. Very odd... but it works, anyway.
