Method

StringgetNoNamespacePath(Stack stack, NamespaceContext ctx)
get No Namespace Path 
StringBuilder ret = new StringBuilder();
for (QName q : stack) {
    if (q == null)
        throw new IllegalStateException("q is null");
    ret.append("/");
    ret.append(q.getLocalPart());
return ret.toString();
...
QNamegetNSName(Element e, String qname)
get NS Name 
if (qname == null) {
    return null;
int i = qname.indexOf(':');
if (i > 0) {
    String name = qname.substring(i + 1);
    String prefix = qname.substring(0, i);
    return new QName(getNamespaceURI(e, prefix), name);
...
ElementgetOrCreateAsFirstElement(Element parentElement, QName elementQName)
get Or Create As First Element 
Element element = getChildElement(parentElement, elementQName);
if (element != null) {
    return element;
Document doc = parentElement.getOwnerDocument();
element = doc.createElementNS(elementQName.getNamespaceURI(), elementQName.getLocalPart());
parentElement.insertBefore(element, getFirstChildElement(parentElement));
return element;
...
QNamegetPartQName(String opName, String suffix, String partName)
part names are not unique across messages. 
return new QName(opName + suffix, partName);
ObjectgetPort(Service service, Class seiClass, QName port)
Convenient method to create a sei using service, sei class and port qname. 
return service.getPort(port, seiClass);
StringgetPrefix(QName qName)
Returns the prefix of the given QName. 
return qNameHasPrefix ? qName.getPrefix() : "";
StringgetQualifiedName(QName qName)
Return the qualified name, that is to say the prefix -if any- with the local name. 
if (!XMLConstants.NULL_NS_URI.equals(qName.getNamespaceURI())
        && !XMLConstants.DEFAULT_NS_PREFIX.equals(qName.getPrefix())) {
    return qName.getPrefix() + ":" + qName.getLocalPart();
} else {
    return qName.getLocalPart();
StringgetServiceCode(SOAPMessage soap, QName requestElementQName)
get Service Code 
for (SOAPElement eachHeaderElement : getChildElements(soap.getSOAPHeader())) {
    QName headerElementQName = eachHeaderElement.getElementQName();
    if (!"service".equals(headerElementQName.getLocalPart())) {
        continue;
    for (SOAPElement eachServicePart : getChildElements(eachHeaderElement)) {
        QName headerPartQName = eachServicePart.getElementQName();
        if (headerPartQName.getLocalPart().equals("serviceCode")) {
...
StringgetString(QName qName)
Get the full string of qname 
if (qName == null)
    throw new NullPointerException("argument is null");
StringBuffer sb = new StringBuffer();
sb.append("NamespaceUri:" + qName.getNamespaceURI() + " ");
sb.append("LocalPart:" + qName.getLocalPart() + " ");
sb.append("Prefix:" + qName.getPrefix());
return sb.toString();
StringgetStringForQName(QName qname, Element e)
Return a string for a particular QName, mapping a new prefix if necessary. 
String uri = qname.getNamespaceURI();
String prefix = getPrefix(uri, e);
if (prefix == null) {
    int i = 1;
    prefix = "ns" + i;
    while (getNamespace(prefix, e) != null) {
        i++;
        prefix = "ns" + i;
