Methods Summary
public intgetLength()
The number of nodes in this map. The range of valid child node indices is 0 to length-1 inclusive.

      return (nodes != null) ? nodes.size() : 0;
public org.w3c.dom.NodegetNamedItem(java.lang.String name)
Retrieves a node specified by name.

param
name The nodeName of a node to retrieve.
return
A Node (of any type) with the specified nodeName, or null if it does not identify any node in this map.

    if(name == null   ){
      Thread.dumpStack();
      throw new java.lang.IllegalArgumentException("local name = null");
    }

   for(Iterator iter = nodes.iterator(); iter.hasNext();){
     Attr attr = (Attr)iter.next();
     if(name.equals(attr.getName())){
       return attr;
     }
   }
   return null;
public org.w3c.dom.NodegetNamedItemNS(java.lang.String namespaceURI, java.lang.String localName)
Retrieves a node specified by local name and namespace URI.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

param
namespaceURI The namespace URI of the node to retrieve.
param
localName The local name of the node to retrieve.
return
A Node (of any type) with the specified local name and namespace URI, or null if they do not identify any node in this map.

      if(namespaceURI == null) namespaceURI = "";
      if(localName == null   ){
        Thread.dumpStack();
        throw new java.lang.IllegalArgumentException("local name = null");
      }

     for(Iterator iter = nodes.iterator(); iter.hasNext();){
       Attr attr = (Attr)iter.next();
       if(namespaceURI.equals(attr.getNamespaceURI()) &&
          localName.equals(attr.getLocalName())){
         return attr;
       }
     }
     return null;
public org.w3c.dom.Nodeitem(int index)
Returns the indexth item in the map. If index is greater than or equal to the number of nodes in this map, this returns null.

param
index Index into this map.
return
The node at the indexth position in the map, or null if that is not a valid index.

      return (nodes != null && index < nodes.size()) ?
                    (Node)(nodes.elementAt(index)) : null;
public org.w3c.dom.NoderemoveNamedItem(java.lang.String name)
Removes a node specified by name. When this map contains the attributes attached to an element, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.

param
name The nodeName of the node to remove.
return
The node removed from this map if a node with such a name exists.
exception
DOMException NOT_FOUND_ERR: Raised if there is no node named name in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.

       if(name == null ){
         Thread.dumpStack();
         throw new java.lang.IllegalArgumentException("local name = null");
       }
       for(int i = 0; i <  nodes.size(); i++){
         Attr attr = (Attr)nodes.get(i);
         // search if we have already
         if(name.equals(attr.getLocalName())){
           nodes.remove(i);
           return attr; // return old one
         }
      }
      return null;
public org.w3c.dom.NoderemoveNamedItemNS(java.lang.String namespaceURI, java.lang.String localName)
Removes a node specified by local name and namespace URI. A removed attribute may be known to have a default value when this map contains the attributes attached to an element, as returned by the attributes attribute of the Node interface. If so, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

param
namespaceURI The namespace URI of the node to remove.
param
localName The local name of the node to remove.
return
The node removed from this map if a node with such a local name and namespace URI exists.
exception
DOMException NOT_FOUND_ERR: Raised if there is no node with the specified namespaceURI and localName in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.

public org.w3c.dom.NodesetNamedItem(org.w3c.dom.Node arg)
Adds a node using its nodeName attribute. If a node with that name is already present in this map, it is replaced by the new one.
As the nodeName attribute is used to derive the name which the node must be stored under, multiple nodes of certain types (those that have a "special" string value) cannot be stored as the names would clash. This is seen as preferable to allowing nodes to be aliased.

param
arg A node to store in this map. The node will later be accessible using the value of its nodeName attribute.
return
If the new Node replaces an existing node the replaced Node is returned, otherwise null is returned.
exception
DOMException WRONG_DOCUMENT_ERR: Raised if arg was created from a different document than the one that created this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
INUSE_ATTRIBUTE_ERR: Raised if arg is an Attr that is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.
HIERARCHY_REQUEST_ERR: Raised if an attempt is made to add a node doesn't belong in this NamedNodeMap. Examples would include trying to insert something other than an Attr node into an Element's map of attributes, or a non-Entity node into the DocumentType's map of Entities.

public org.w3c.dom.NodesetNamedItemNS(org.w3c.dom.Node arg)
Adds a node using its namespaceURI and localName. If a node with that namespace URI and that local name is already present in this map, it is replaced by the new one.

param
arg A node to store in this map. The node will later be accessible using the value of its namespaceURI and localName attributes.
return
If the new Node replaces an existing node the replaced Node is returned, otherwise null is returned.

NOT_SUPPORTED_ERR: Always thrown if the current document does not support the "XML" feature, since namespaces were defined by XML.
