I made a get request and store the response in a String response:

HttpClient client = new DefaultHttpClient(); 
String getURL = "some_url_with_param_values";
HttpGet get = new HttpGet(getURL);
HttpResponse responseGet = client.execute(get);  
HttpEntity resEntityGet = responseGet.getEntity();   
String response = EntityUtils.toString(resEntityGet);

But I am only interested in the <div>s that has the class name <div class="product-data">. So, I did this:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
InputSource is;
builder = factory.newDocumentBuilder();
is = new InputSource(new StringReader(xml));
Document doc = builder.parse(is);
NodeList list = doc.getElementsByTagName("product-data"); //I even tried: (div class="product-data)
String test = list.item(0).getNodeValue(); //Just to test it

Unfortunately, it didn’t work. Any help will be appreciated.

My response string is basically an html page.

<!DOCTYPE html .....
<html>
<head>
    //some script tags
</head>
<body>
    //some tags
    <div class="product-data">
        //some other tags
    </div>
    //some tags
    <div class="product-data">
        //some other tags
    </div>
    ....
</body>  
</html>

    I think you should try using getElementsByClassName('product-data')

    If that doesn’t work you could always check Jsoup, it provides an library which gives an easy way of extracting Html elements from a webpage

    DefaultHttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(url.toURI());
HttpResponse resp = client.execute(get);

String content = EntityUtils.toString(resp.getEntity());
Document doc = Jsoup.parse(content);
Elements ele = doc.select("div.classname");

    This example executes an Http GET and then extracts all Div elements with the class “classname” which you can then do what you like with
