  <p>i need to split my file at the delimiter '.' and save what we have before it in a string. How can i do that ? i tried the following but it does not work</p>
  
  <pre><code>try {
      String sCurrentLine = null;
      int i = 0;
      br = new BufferedReader(new FileReader(rdfInstanceFile));
      while ((sCurrentLine = br.readLine()) != null) {
          splitted = sCurrentLine.split(".");
      }
  } catch (IOException e) {
      e.printStackTrace();
  }
