voidremoveWhitespaceTextNodes(Element parent)
Traverserses through a DOM tree starting at the given element and removes all those text-nodes from it that only contain whitespaces. 
final NodeList nl = parent.getChildNodes();
for (int i = 0; i < nl.getLength(); i++) {
    final Node child = nl.item(i);

    } else if (child.getNodeType() == Node.ELEMENT_NODE && child.getChildNodes().getLength() > 0) {
        removeWhitespaceTextNodes((Element) child);
