Java: ignoring screens in XML parsing

Question

I use DocumentBuilder to parse XML files. However, the project specification requires that lines of text, such as "and <, be returned literally and not decoded as characters ( "and <).

A previous similar question, Read the escaped quote as a hidden quote from xml , got one answer that seems to be specific to Apache, and another that looks just don't do what it says. I would love to be mistaken in both calculations :)

For reference, here is some code:

  file = new File(fileName);
  DocBderFac = DocumentBuilderFactory.newInstance();
  DocBder = DocBderFac.newDocumentBuilder();
  doc = DocBder.parse(file);

  NodeList textElmntLst = doc.getElementsByTagName(text);
  Element textElmnt = (Element) textElmntLst.item(0);

  NodeList txts = textElmnt.getChildNodes(); 
  String txt = ((Node) txts.item(0)).getNodeValue();
  System.out.println(txt);

I would like println () to create things like

"3>2"

instead

"3>2"

which is happening now. Thank!
