[android-developers] RSS Normalizing Crashes App

[AJ Quick]

I'm writing a script that takes a RSS and phrases items.. but it is
crashing on part of the code.

I'm using the code from: http://www.devx.com/wireless/Article/39810/1954

private void DownloadRSS(String URL)
    {
        InputStream in = null;
        try {
            in = OpenHttpConnection(URL);
            Document doc = null;
            DocumentBuilderFactory dbf =
                DocumentBuilderFactory.newInstance();
            DocumentBuilder db;

            try {
                db = dbf.newDocumentBuilder();
                doc = db.parse(in);
            } catch (ParserConfigurationException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (SAXException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            doc.getDocumentElement().normalize();

            //---retrieve all the <item> nodes---
            NodeList itemNodes = doc.getElementsByTagName("item");

            String strTitle = "";
            for (int i = 0; i < itemNodes.getLength(); i++) {
                Node itemNode = itemNodes.item(i);
                if (itemNode.getNodeType() == Node.ELEMENT_NODE)
                {
                    //---convert the Node into an Element---
                    Element itemElement = (Element) itemNode;

                    //---get all the <title> element under the <item>
                    // element---
                    NodeList titleNodes =
                        (itemElement).getElementsByTagName("title");

                    //---convert a Node into an Element---
                    Element titleElement = (Element) titleNodes.item
(0);

                    //---get all the child nodes under the <title>
element---
                    NodeList textNodes =
                        ((Node) titleElement).getChildNodes();

                    //---retrieve the text of the <title> element---
                    strTitle = ((Node) textNodes.item(0)).getNodeValue
();

                    //---display the title---
                    Toast.makeText(getBaseContext(),strTitle,
                        Toast.LENGTH_SHORT).show();
                }
            }
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }



It is crashing the app when it gets to: doc.getDocumentElement
().normalize();

(And it won't work without it.. Some work.. some RSS files do not.)

Is this the best way to do it? I want to load the fields "title" and
"link" into an array.. and then list them and make it clickable.
