XML parse file from HTTP

Try using URLConnection.getInputStream() for getting the handle of XML file.

See the below code, in that I am trying to open an xml file and printing all the description fields:

import java.io.InputStream;import java.net.URL;import java.net.URLConnection;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import org.w3c.dom.Document;import org.w3c.dom.NodeList;public class HTTPXMLTest{    public static void main(String[] args)     {        try {            new HTTPXMLTest().start();        } catch (Exception e) {            e.printStackTrace();        }    }    private void start() throws Exception    {        URL url = new URL("http://localhost:8080/AutoLogin/resource/web.xml");        URLConnection connection = url.openConnection();        Document doc = parseXML(connection.getInputStream());        NodeList descNodes = doc.getElementsByTagName("description");        for(int i=0; i<descNodes.getLength();i++)        {            System.out.println(descNodes.item(i).getTextContent());        }    }    private Document parseXML(InputStream stream)    throws Exception    {        DocumentBuilderFactory objDocumentBuilderFactory = null;        DocumentBuilder objDocumentBuilder = null;        Document doc = null;        try        {            objDocumentBuilderFactory = DocumentBuilderFactory.newInstance();            objDocumentBuilder = objDocumentBuilderFactory.newDocumentBuilder();            doc = objDocumentBuilder.parse(stream);        }        catch(Exception ex)        {            throw ex;        }               return doc;    }}

Here is the simple example for getting data form this string "http://www.gettingagile.com/feed/rss2/"

public class MainClassXml {    public static void main(String args[]) throws URISyntaxException,            ClientProtocolException, IOException, MalformedURLException {        String url = "http://www.gettingagile.com/feed/rss2/";        System.out.println("Url is careated****");        URL url2 = new URL(url);        HttpGet httpGet = new HttpGet(url);        HttpClient httpClient = new DefaultHttpClient();        HttpResponse httpResponse = httpClient.execute(httpGet);        HttpEntity entity = httpResponse.getEntity();        System.out.println("Entity is*****" + entity);        try {            String xmlParseString = EntityUtils.toString(entity);            System.out.println("This Stirng to be Pasrse***" + xmlParseString);            HttpURLConnection connection = (HttpURLConnection) url2                    .openConnection();            InputStream inputStream = connection.getInputStream();            DocumentBuilderFactory builderFactory = DocumentBuilderFactory                    .newInstance();            DocumentBuilder documentBuilder = builderFactory                    .newDocumentBuilder();            Document document = documentBuilder.parse(inputStream);            document.getDocumentElement().normalize();            System.out.println("Attributes are***" + document.getAttributes());            NodeList nodeList = document.getElementsByTagName("rss");            System.out.println("This is firstnode" + nodeList);            for (int getChild = 0; getChild < nodeList.getLength(); getChild++) {                Node Listnode = nodeList.item(getChild);                System.out.println("Into the for loop"                        + Listnode.getAttributes().getLength());                Element firstnoderss = (Element) Listnode;                System.out.println("ListNodes" + Listnode.getAttributes());                System.out.println("This is node list length"                        + nodeList.getLength());                Node Subnode = nodeList.item(getChild);                System.out.println("This is list node" + Subnode);                System.out.println("rss attributes***************");            }        } catch (Exception exception) {            System.out.println("Exception is" + exception);        }    }

Get rid of the new File():

Document doc = builder.parse(url);
