How to read a InputStream with UTF-8?

Question

Welcome all

I'm developing a Java app, that calls a PHP from internet that it's giving me a XML response.

In the response is contained this word: "Próximo", but when i parse the nodes of the XML and obtain the response into a String variable, I'm receiving the word like this: "Pr& oacute;ximo".

I'm sure that the problem is that i'm using different encoding in the Java app then encoding of PHP script. Then, i supose i must set encoding to the same as in your PHP xml, UTF-8

This is the code i'm using to geat the XML file from the PHP.

¿What should i change in this code to set the encoding to UTF-8? (note that im not using bufered reader, i'm using input stream)

        InputStream in = null;
        String url = "http://www.myurl.com"
        try {                              
            URL formattedUrl = new URL(url); 
            URLConnection connection = formattedUrl.openConnection();   
            HttpURLConnection httpConnection = (HttpURLConnection) connection;
            httpConnection.setAllowUserInteraction(false);
            httpConnection.setInstanceFollowRedirects(true);
            httpConnection.setRequestMethod("GET");
            httpConnection.connect();               
            if (httpConnection.getResponseCode() == HttpURLConnection.HTTP_OK)
                in = httpConnection.getInputStream();   

            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();                     
            DocumentBuilder db = dbf.newDocumentBuilder();
            Document doc = db.parse(in);
            doc.getDocumentElement().normalize();             
            NodeList myNodes = doc.getElementsByTagName("myNode");

When you get your InputStream read byte[]s from it. When you create your Strings, pass in the CharSetfor "UTF-8". Example:

byte[] buffer = new byte[contentLength];
int bytesRead = inputStream.read(buffer);
String page = new String(buffer, 0, bytesRead, "UTF-8");

Note, you're probably going to want to make your buffer some sane size (like 1024), and continuously called inputStream.read(buffer).

Yes, you can also use an InputStreamReader, and try changing the parse() line to:

Document doc = db.parse(new InputSource(new InputStreamReader(in, "UTF-8")));
