Text Content of Document is returned as null

Question

Hi All,
I am trying to use the JTidy parser to parse an input HTML string. But when I am trying to type the content of the Document, it is returning null. I am new to DOM parsing, so is there anything that I am doing wrong? Any pointer will be very helpful.
Here is my code:
public static void main(String[] args) {
          String rawHtml = "<p class=\"MsoNormal\" style=\"text-autospace:none;\"><font color=\"black\"><span style=\"color:black;\">???</span></font><b><font color=\"#7f0055\"><span style=\"color:#7f0055;font-weight:bold;\">private</span></font></b><font color=\"black\"><span style=\"color:black;\"> String parseDescription</span></font><font>";
          Tidy tidy = new Tidy();     //obtain a new Tidy parser instance
          tidy.setPrintBodyOnly(true);
          ByteArrayOutputStream baos = new ByteArrayOutputStream();
          PrintStream ps = new PrintStream(baos);
          byte[] bytes = rawHtml.getBytes();
          ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
          //returns HTML Document
          Document htmlDoc = tidy.parseDOM(bais, ps);
          String docText = htmlDoc.getTextContent();
          try {
               System.out.print(baos.toString("UTF8"));
               System.out.println();
               try {
                    System.out.print(docText);
               } catch (DOMException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
          } catch (UnsupportedEncodingException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
Here is the output:
line 1 column 302 - Warning: missing </font>
line 1 column 302 - Warning: trimming empty <font>
line 1 column 303 - Warning: inserting missing 'title' element
InputStream: Document content looks like HTML 4.01 Transitional

You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.
<p class="MsoNormal" style="text-autospace:none;"><font color=
"black"><span style="color:black;">???</span></font><b><font color=
"#7F0055"><span style=
"color:#7f0055;font-weight:bold;">private</span></font></b><font
color="black"><span style="color:black;">String
parseDescription</span></font></p>
null

getTextContent() is a dom level 3 recommendation, it may not be supported by every dom parser - and it is not by JTidy (yet). One way to do it is to write your own method to get the same. But you sure can chain the now well-formed output of JTidy to a full-fledged dom parser, say, such as oracle.xml.parser.v2.DomParser. The detail can be done like this.
[0] Add oracle xdk's xmlparserv2.jar to the classpath.
[1] Add the import to the program for convenience.
import import oracle.xml.parser.v2.*;[2] Then the chaining to get the getTextContent() available.
DOMParser parser=new DOMParser();
try {
    parser.parse(new ByteArrayInputStream(baos.toByteArray()));
    Document xdoc=parser.getDocument();
    System.out.println(xdoc.getDocumentElement().getTextContent());
} catch (Exception e) {
    e.printStackTrace();
}[3] With xdoc, you can do more things to your liking as it is now a full-fledged dom tree.
