Parsing Deep Xml file using DOM Parser

I have the following XML file:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE output SYSTEM "resources/schema/AISE.dtd">
<output xmlns='urn:columbia:ccls:aiSE:0.1'>
    <sentence>

            </token>
        </rootToken>   
        <rootToken value ='are'>
            <token value ='are'>

            </token>
        </rootToken>
        <rootToken value =' thing.'>
            <token value ='thing'>

            </token>

                <solution CI_class ='FA' />
            </token>
        </rootToken>

    <sentence>
        <rootToken value ='We'>
            <token value ='We'>
                <solution CI_class ='FA' />
            </token>
        </rootToken>

        </rootToken>
        <rootToken value ='you'>
            <token value ='you'>
                <solution CI_class ='FA' />
            </token>
        </rootToken>
        <rootToken value ='to'>
            <token value ='to'>
                <solution CI_class ='FA' />

        </rootToken>
        <rootToken value ='move'>
            <token value ='move'>

                <solution CI_class ='FA' />
            </token>
         </rootToken>
    </sentence>
</output>

I would like to parse this file and generate the following file with the following output:

    Sentnece1: We    FA
               can   FA
               wait  FA
               For   FA
               you   FA
               to    FA
               move  FA
               back  FA
               .     FA

    Sentence2: They   FA
               are    FA
               the    FA
               same   FA
               thing  FA

My problem is that I'm would like print the a new line character that splits the two sentences. I could get the above output without having any separator.So, I don't know what I'm missing.

This is the code I'm using to parse the XML file:

        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(fXmlFile);
        FileWriter out = new FileWriter("OUT-TEST.txt");

        doc.getDocumentElement().normalize();

        System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
            out.write("Root element :"+ doc.getDocumentElement().getNodeName() +"\n");

                                      System.out.println("Token : " + tElement.getAttribute("value"));                                                           
                                      out.write(tElement.getAttribute("value")+"\t");

                                      if(tNode.hasChildNodes()){

                                          Element cElement = (Element) cNode;
