Parsing external XML for JSON in Java?

Question

So, am I sitting here with a Google Geocoder that returns XML via 'GOOGLE_URL / xml? address = input & sensor = false '. I need to get it using Java and parse it into a JSON object and send it forward.

How am I going to do this? (No, this is not homework) Please note that it is advisable to do this in standard libraries. At the moment I am trying to work if it can be done, for example, SAX.

Answer 1

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

• Connect to the URL and load 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();
  

• JSON . ( , .)

• XML JSON:

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