Description

The list of methods to do XML Element Check are organized into topic(s).

Method

booleanis(final Element e, final String tag)
is 
return e.getTagName().equalsIgnoreCase(tag);
booleanisAncestor(Element candAnc, Node cand)
Check, if a given DOM element is an ancestor of a given node. 
Node currPar = cand.getParentNode();
while (currPar != null) {
    if (candAnc == currPar)
        return true;
    currPar = currPar.getParentNode();
return false;
booleanisAppearanceTag(Element e)
is Appearance Tag 
if (e.getTagName().matches("H[1-9]")) {
    return true;
if (e.getTagName().equals("FONT") && !e.getAttribute("COLOR").equals("")) {
    return true;
if (e.getTagName().matches("[B|I|STRONG]")) {
    return true;
...
booleanisAsyncEventQueue(Element element)
is Async Event Queue 
return ASYNC_EVENT_QUEUE_ELEMENT_NAME.equals(element.getLocalName());
booleanisComputedGoal(final Element element)
Check if an element describes a computed goal or not. 
return "computedGoal".equals(element.getNodeName());
booleanisElement(XMLStreamReader xmlRdr, int eventType, String tagName)
is Element 
int event = xmlRdr.getEventType();
if (event == eventType) {
    String locName = xmlRdr.getLocalName();
    if (locName.equals(tagName))
        return true;
return false;
booleanisElementExistsByTagName(final Element element, final String tagName)
Checks if is element exists by tag name. 
if (element == null || tagName == null || tagName.isEmpty()) {
    return false;
final NodeList res = element.getChildNodes();
for (int i = 0; i < res.getLength(); i++) {
    final Node node = res.item(i);
    if (node.getNodeType() == Node.ELEMENT_NODE) {
        final Element elem = (Element) node;
...
booleanisElementNamed(Element e, String ns, String localName)
Shortcut for checking a DOM element node's namespace and local name 
return (e != null && safeCompare(ns, e.getNamespaceURI()) && safeCompare(localName, e.getLocalName()));
booleanisEmpty(final Element el)
See if this node is empty 
return !hasChildren(el) && !hasContent(el);
booleanisEmptyElement(Element el)
Check that an element is empty, i.e., it contains no non-whitespace text or elements as children. 
NodeList nl = el.getChildNodes();
int len = nl.getLength();
for (int i = 0; i < len; ++i) {
    switch (nl.item(i).getNodeType()) {
    case Node.CDATA_SECTION_NODE:
    case Node.TEXT_NODE:
        String s = nl.item(i).getNodeValue();
        if (s != null && s.trim().length() > 0) {
