    <p>I'm trying to parse an RSS feed from mens health using the document builder. It isn't working and when I debug I don't get an error. I think the issues lies with the element lines, as I don't really understand if I'm getting the correct values. Here is my code:</p> <pre><code>private void refreshTips(){ //Get the XML URL url; try { String tipFeed = getString(R.string.tip_feed); url = new URL(tipFeed); URLConnection connection; connection = url.openConnection(); HttpURLConnection httpConnection = (HttpURLConnection)connection; int responseCode = httpConnection.getResponseCode(); if(responseCode == HttpURLConnection.HTTP_OK){ InputStream in = httpConnection.getInputStream(); DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); //Parse the menshealth feed Document dom = db.parse(in); Element docEle = dom.getDocumentElement(); //Clear the old tips tips.clear(); //Get a list of each tip entry NodeList nl = docEle.getElementsByTagName("item"); if(nl != null &amp;&amp; nl.getLength() &gt;0){ for(int i=0; i &lt; nl.getLength(); i++){ Element item = (Element)nl.item(i); Element title = (Element)item.getElementsByTagName("title").item(0); Element link = (Element)item.getElementsByTagName("link").item(0); Element details = (Element)item.getElementsByTagName("description").item(0); Element when = (Element)item.getElementsByTagName("pubDate").item(0); String _title = title.getNodeValue(); String _link = link.getNodeValue(); String _det = details.getNodeValue(); String _date = when.getNodeValue(); SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss'Z'"); Date tDate = new GregorianCalendar(0,0,0).getTime(); try{ tDate = sdf.parse(_date); }catch(ParseException e){ e.printStackTrace(); } catch (java.text.ParseException e) { e.printStackTrace(); } Tip tip = new Tip(tDate, _title, _det, _link); addNewTip(tip); } } } }catch(MalformedURLException e){ e.printStackTrace(); }catch(IOException e){ e.printStackTrace(); }catch(ParserConfigurationException e){ e.printStackTrace(); }catch(SAXException e){ e.printStackTrace(); } finally { } } private void addNewTip(Tip tip){ tips.add(tip); aa.notifyDataSetChanged(); } </code></pre>

    1. COFound this error code: <code> 04-27 18:16:07.027: WARN/System.err(9200): org.xml.sax.SAXParseException: PI must not start with xml (position:unknown xm@2:5 in java.io.InputStreamReader@480e2538) </code> Which is apparently caused by white space before the <?xml> definition. Having checked the file http://www.menshealth.com/cda/newssliderenhancedxml.do?rss=yes I can see that there is white space before the definition, how do I get around this? Cheers

    2. COCan I suggest using the Simple XML library to do your parsing instead of the document builder? http://massaioli.homelinux.com/wordpress/2011/04/21/simple-xml-in-android-1-5-and-up/

    3. COI got it to work with a different XML stream. I think the problem lies with the mens health XML feed - the xml delcaration isn't on the first line.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
