Log.e("rsport-", "function1");
 try{
  DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
  factory.setIgnoringComments(true);
  factory.setCoalescing(true); // Convert CDATA to Text nodes
  factory.setNamespaceAware(false); // No namespaces: this is default
  factory.setValidating(false); // Don't validate DTD: also default
  DocumentBuilder parser = factory.newDocumentBuilder();
  Log.e("rsport-", "function2");
  Document document = parser.parse("http://demo.greatinnovus.com/restingspot/search?userid=xxxxxxxxxxxxxxxx&firstname=a&lastname=a");
  Log.e("rsport-","function3"); 
   NodeList sections = document.getElementsByTagName("Searchdata"); 
     int numSections = sections.getLength();
       for (int i = 0; i < numSections; i++) 
     {
       Element section = (Element) sections.item(i); 
       if(section.hasChildNodes()==true){
           NodeList section1=section.getChildNodes();
              for(int j=0;j<section1.getLength();j++){
                if(section1.item(j).hasChildNodes()==true) {
                    for(int k=0;k<section1.item(j).getChildNodes().getLength();k++)                     
                                 xmlvalue=String.valueOf(section1.item(j).getChildNodes().item(k).getNodeValue()).trim();

                                 arl.add(xmlvalue);

Refer my blog, i had gave Detailed explanation, http://sankarganesh-info-exchange.blogspot.com/2011/04/parsing-data-from-internet-and-creating.html, and make sure , that you had add the Internet permission in your Manifest file.

If you had gone through Myblog, then you will able to notice that you did the following line as wrong

 Document document = parser.parse("http://demo.greatinnovus.com/restingspot/search?userid=xxxxxxxxxxxxxxxx&firstname=a&lastname=a");

use like this

URL url =new URL("http://demo.greatinnovus.com/restingspot/search?userid=xxxxxxxxxxxxxxxx&firstname=a&lastname=a");
 Document document= parser.parse(new InputSource(url.openStream()));
