Question

In my Android application, I want to retrieve an XML file from the internet and parse some tags in that file to my application. I got a working tutorial here which uses XMLResourceParser but that tutorial points out how to read an XML file from a local directory.

What are the method calls to retrieve an external XML file into my Android application?

XmlResourceParser xrp = this.getResources().getXml(R.xml.test);

You can get an InputStream to the XML file using the following code:

URL url = new URL(urlString);
URLConnection connection = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection)connection;
httpConn.setDoInput(true);
httpConn.setRequestProperty("charset", "utf-8");
int responseCode = httpConn.getResponseCode();
if(responseCode != HttpStatus.SC_OK) {
    InputStream xmlStream = httpConn.getInputStream();

    // Pass the xmlStream object to a XPP, SAX or DOM parser.
}
