Parsing external XML to JSON in Java?

Question

So I\'m sitting here with Google Geocoder, which returns an XML via \'GOOGLE_URL/xml?address=input&sensor=false\'. I need to fetch it by using Java and parse it into a J

Answer 1

Here is a working example which shows how to connect to a URL, download XML and convert it to JSON format:

1. Connect to a URL and download the XML as a string:

   String str = "http://maps.google.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true";
   URL url = new URL(str);
   InputStream is = url.openStream();
   int ptr = 0;
   StringBuilder builder = new StringBuilder();
   while ((ptr = is.read()) != -1) {
       builder.append((char) ptr);
   }
   String xml = builder.toString();
   

2. Download the JSON library from here. (You will have to compile it and ensure that the classes are on your classpath.)

3. Convert the XML into a JSON Object:

   JSONObject jsonObject = XML.toJSONObject(xml);
   System.out.println(jsonObject);
   

Answer 2

Why don't you retrieve the Google geocode as JSON in the first place?

• http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true
