Not being able to store value from ReadLine (bufferedReader)

So I'm having issues with being able to save values using the method readLine() in bufferedReader, here is how my code is looking currently:

            in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
            while((inputLine=in.readLine())!= null)
                try { g.doc.insertString(g.doc.getLength(), "\n" + new Xmlgetter(inputLine).outString, g.style); 
                }
                catch (BadLocationException e){
                    e.printStackTrace();
                }

What I want to achieve is to be able to use the value of inputLine twice. The problem I'm running into is no matter how I try to save it I call on in.readLine(), which when called on a second time is empty. Ideas?

Store the read value into a variable and reuse it any time you need it.

Use the usual pattern:

variable = readValue;
while (variable != null) {
    // use the variable value any times
    variable = readNextValue;
}
