Sorry I\'m a Java/XML newbie - and can\'t seem to figure this one out. It seems it\'s possible to convert a Document object to a string. However, I want to convert a Node ob

Answer 1

String getNodeString(Node node) {
    try {
        StringWriter writer = new StringWriter();
        Transformer transformer = TransformerFactory.newInstance().newTransformer();
        transformer.transform(new DOMSource(node), new StreamResult(writer));
        String output = writer.toString();
        return output.substring(output.indexOf("?>") + 2);//remove <?xml version="1.0" encoding="UTF-8"?>
    } catch (TransformerException e) {
        e.printStackTrace();
    }
    return node.getTextContent();
}

You can use a Transformer (error handling and optional factory configuration omitted for clarity):

Node node = ...;
StringWriter writer = new StringWriter();
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(new DOMSource(node), new StreamResult(writer));
String xml = writer.toString();
// Use xml ...

This is way to convert Node to html

public static String getInnerHTML(Node node) throws TransformerConfigurationException, TransformerException
{
    StringWriter sw = new StringWriter();
    Result result = new StreamResult(sw);
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer proc = factory.newTransformer();
    proc.setOutputProperty(OutputKeys.METHOD, "html");
    for (int i = 0; i < node.getChildNodes().getLength(); i++)
    {
        proc.transform(new DOMSource(node.getChildNodes().item(i)), result);
    }
    return sw.toString();
}
