Method

voidremove(Element element, Predicate shouldRemovePredicate)
Removes child elements that meet a certain condition. 
NodeList childNodes = element.getChildNodes();
int i = 0;
while (i < childNodes.getLength()) {
    Node currentNode = childNodes.item(i);
    Element child = (currentNode instanceof Element) ? ((Element) currentNode) : null;
    if (child != null && shouldRemovePredicate.test(child)) {
        element.removeChild(currentNode);
    } else {
...
voidremoveAll(Element node, String subElement)
remove All 
for (Element e : findAll(node, subElement))
    node.removeChild(e);
voidremoveContent(Element element)
remove Content 
NodeList nodeList = element.getChildNodes();
while (nodeList.getLength() > 0) {
    element.removeChild(nodeList.item(0));
voidremoveElements(Element from, String named)
Removes all children named named from element from 
NodeList children = from.getChildNodes();
boolean removeNextNewline = false;
List<Node> removes = new ArrayList<Node>();
for (int i = 0; i < children.getLength(); i++) {
    Node child = children.item(i);
    if ((child != null) && named.equals(child.getNodeName())) {
        removes.add(child);
        removeNextNewline = true;
...
NoderemoveEmptyElements(Node node)
Takes the supplied node and recursively removes empty (no content/child nodes) elements 
NodeList list = selectNodeList(node, "*[string-length(normalize-space(.)) = 0]");
for (int i = 0; i < list.getLength(); i++) {
    node.removeChild(list.item(i));
if (node.hasChildNodes()) {
    NodeList childs = node.getChildNodes();
    for (int i = 0; i < childs.getLength(); i++) {
        if (childs.item(i) instanceof Element) {
...
voidremovePreviousSiblingText(Element element)
Removes any previous siblings text nodes 
while (true) {
    Node sibling = element.getPreviousSibling();
    if (sibling instanceof Text) {
        detach(sibling);
    } else {
        break;
voidremoveSchemaLocation(Element el)
remove Schema Location 
NamedNodeMap children;
Node node;
Attr attribute;
String xsi = null;
children = el.getAttributes();
for (int i = 0; i < children.getLength(); i++) {
    node = children.item(i);
    if (node instanceof Attr) {
...
voidremoveTopPi(Element e, Element pi)
Remove the Pi on top of e 
Element piContainer = (Element) pi.getParentNode();
piContainer.replaceChild(e, pi);
voidremoveWhitespaceNodes(Element e)
Removes whitespace from element content. 
NodeList children = e.getChildNodes();
for (int i = children.getLength() - 1; i >= 0; i--) {
    Node child = children.item(i);
    if (child instanceof Text && ((Text) child).getData().trim().length() == 0) {
        e.removeChild(child);
    } else if (child instanceof Element)
        removeWhitespaceNodes((Element) child);
voidremoveWhitespaceNodes(Element e)
Helper function that removes whitespace nodes from Element objects to allow for easier parsing 
NodeList children = e.getChildNodes();
for (int i = children.getLength() - 1; i >= 0; i--) {
    Node child = children.item(i);
    if (child instanceof Text && ((Text) child).getData().trim().length() == 0) {
        e.removeChild(child);
    } else if (child instanceof Element) {
        removeWhitespaceNodes((Element) child);
