Usage

From source file:Main.java

public static String elementToString(Element element) {
    Document document = element.getOwnerDocument();
    DOMImplementationLS domImplLS = (DOMImplementationLS) document.getImplementation();
    LSSerializer serializer = domImplLS.createLSSerializer();

    // Client assumes/requires UTF-8 response.
    LSOutput lsOutput = domImplLS.createLSOutput();
    lsOutput.setEncoding("UTF-8");

    StringWriter stringWriter = new StringWriter();
    lsOutput.setCharacterStream(stringWriter);
    serializer.write(element, lsOutput);

    return stringWriter.toString();
}
