Java Utililty Methods XML Attribute Namespace

int countNonNamespaceAttribures(NamedNodeMap attrs)
count Non Namespace Attribures

int n = 0;
for (int i = 0; i < attrs.getLength(); i++) {
 Attr attr = (Attr) attrs.item(i);
 if (!attr.getName().startsWith("xmlns")) {
 n++;
return n;
...

String getNamespaceDeclarationPrefix(Attr attr)
get Namespace Declaration Prefix

if (!W3C_XML_SCHEMA_XMLNS_URI.equals(attr.getNamespaceURI())) {
 throw new IllegalStateException(
 "Attempt to get prefix from a attribute that is not a namespace declaration, it has namespace "
 + attr.getNamespaceURI());
String attrName = attr.getName();
if (attrName.startsWith("xmlns:")) {
 return attrName.substring(6);
...

boolean isNamespaceDef(Attr attr)
Check if the attribute node is a namespace definition.

String prefix = attr.getPrefix();
return (prefix != null && prefix.equals(XMLConstants.XMLNS_ATTRIBUTE))
 || attr.getNodeName().equals(XMLConstants.XMLNS_ATTRIBUTE);

boolean isNamespaceDefinition(Attr attr)
is Namespace Definition

if (W3C_XML_SCHEMA_XMLNS_URI.equals(attr.getNamespaceURI())) {
 return true;
if (attr.getName().startsWith("xmlns:") || "xmlns".equals(attr.getName())) {
 return true;
return false;

boolean isNoNamespaceAttribute(final XMLStreamReader reader, final int index)
is No Namespace Attribute

String namespace = reader.getAttributeNamespace(index);
return namespace == null || XMLConstants.NULL_NS_URI.equals(namespace);

String searchParentNamespaces(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)
