output of entities

[Tom Schindl <to...@bestsolution.at>]

hello,

I have the following problem:

reading in a xml-document containing

<hello>World &amp; Universe</hello>

and writing it out using

----------------------8<--------------------------------

DOMParser parser = new DOMParser();
parser.parse("/some/file.xml");
doc = parser.getDocument();
printDOMTree(doc);

----------------------8<--------------------------------

----------------------8<--------------------------------

    public void printDOMTree(Node node)
    {
        int type = node.getNodeType();
        switch (type)
        {
            case Node.DOCUMENT_NODE:
            {
                System.out.println("<?xml version=\"1.0\" ?>");
                printDOMTree(((Document)node).getDocumentElement());
                break;
            }
            case Node.ELEMENT_NODE:
            {
                System.out.print("<");
                System.out.print(node.getNodeName());
                NamedNodeMap attrs = node.getAttributes();
                for (int i = 0; i < attrs.getLength(); i++)
                {
                    Node attr = attrs.item(i);
                    System.out.print(" " + attr.getNodeName() +
                    "=\"" + attr.getNodeValue() +
                    "\"");
                }
                System.out.println(">");
                
                NodeList children = node.getChildNodes();
                if (children != null)
                {
                    int len = children.getLength();
                    for (int i = 0; i < len; i++)
                        printDOMTree(children.item(i));
                }
                
                break;
            }
            case Node.ENTITY_REFERENCE_NODE:
            {
                System.out.print("&");
                System.out.print(node.getNodeName());
                System.out.print(";");
                break;
            }
            case Node.TEXT_NODE:
            {
                System.out.print(node.getNodeValue());
                break;
            }
        }
    }
----------------------8<--------------------------------
prints

<hello>World & Universe</hello>

instead of

<hello>World &amp; Universe</hello>

How could I turn off resolving of entities??

Thanks,
Tom

p.s. already tried some features but with no success.

You are taking the wrong approach. Your code that
outputs the text value must check each character and
escape ampersands (&) and less-than (<) characters.
