Method

String[]getAttributeNames(Element el)
Gets a list of all attribute names for the given DOM element. 
NamedNodeMap map = el.getAttributes();
int len = map.getLength();
String[] attrNames = new String[len];
for (int i = 0; i < len; i++) {
    Attr attr = (Attr) map.item(i);
    attrNames[i] = attr == null ? null : attr.getName();
return attrNames;
...
ListgetAttributeNames(Element element)
get Attribute Names 
List<String> names = new ArrayList<String>();
NamedNodeMap list = element.getAttributes();
for (int i = 0; i < list.getLength(); i++) {
    names.add(list.item(i).getNodeName());
return names;
ListgetAttributeNames(final Element e)
Get a list of the attribute names of an element. 
if (e == null) {
    return null;
final List<String> result = new ArrayList<>();
final NamedNodeMap map = e.getAttributes();
for (int i = 0; i < map.getLength(); i++) {
    final Node attribute = map.item(i);
    result.add(attribute.getNodeName());
...
NodegetAttributeNode(Node sNode, String attribName)
Decide if the node is text, and so must be handled specially 
NamedNodeMap attrs = sNode.getAttributes();
if (attrs != null) {
    return attrs.getNamedItem(attribName);
return null;
NodegetAttributeNode(Node sNode, String attribName)
get Attribute Node 
NamedNodeMap attrs = sNode.getAttributes();
if (attrs != null) {
    return attrs.getNamedItem(attribName);
return null;
ListgetAttributeNodeList(Element element, Pattern name)
get Attribute Node List 
NamedNodeMap nodes = element.getAttributes();
List<Node> attributes = new ArrayList<>();
int i, size = nodes.getLength();
Node node;
for (i = 0; i < size; i++) {
    node = nodes.item(i);
    if (name.matcher(node.getNodeName()).find())
        attributes.add(node);
...
StringgetAttributeNS(Element el, String namespaceURI, String localPart)
Returns the value of an attribute of an element. 
String sRet = null;
Attr attr = el.getAttributeNodeNS(namespaceURI, localPart);
if (attr != null) {
    sRet = attr.getValue();
return sRet;
StringgetAttributeNS(Element elem, String namespace, String att)
get Attribute NS 
String res = elem.getAttributeNS(namespace, att);
return res.length() == 0 && !elem.hasAttributeNS(namespace, att) ? null : res;
QNamegetAttributeNSName(Element e, String attrName)
get Attribute NS Name 
String attrValue = e.getAttribute(attrName);
return getNSName(e, attrValue);
StringgetAttributeNSOrNull(Element e, String name, String nsURI)
get Attribute NS Or Null 
Attr a = e.getAttributeNodeNS(nsURI, name);
if (a == null)
    return null;
return a.getValue();
