StringgetNamespaceDeclarationPrefix(Attr attr)
get Namespace Declaration Prefix

    throw new IllegalStateException(
            "Attempt to get prefix from a attribute that is not a namespace declaration, it has namespace "

booleanisNamespaceDef(Attr attr)
Check if the attribute node is a namespace definition. 
String prefix = attr.getPrefix();

booleanisNoNamespaceAttribute(final XMLStreamReader reader, final int index)
is No Namespace Attribute 
String namespace = reader.getAttributeNamespace(index);
return namespace == null || XMLConstants.NULL_NS_URI.equals(namespace);
StringsearchParentNamespaces(Node xml, String attribute)
Traverses up the XML Document tree looking for XML an namespace declaration that matches the given attribute. 
Node next = xml;
String uri = null;
while (next != null && (uri == null || uri.length() == 0)) {
    if (next.getNodeType() == Node.ELEMENT_NODE)
        uri = ((Element) next).getAttribute(attribute);
    next = next.getParentNode();
if (uri != null && uri.length() == 0)
