Class ElementNSImpl

All Implemented Interfaces:
Cloneable, Element, EventTarget, Node, NodeList, TypeInfo

public class ElementNSImpl extends ElementImpl
ElementNSImpl inherits from ElementImpl and adds namespace support.

The qualified name is the node name, and we store localName which is also used in all queries. On the other hand we recompute the prefix when necessary.

    • getNamespaceURI

      public String getNamespaceURI()
      Introduced in DOM Level 2.

      The namespace URI of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE, this is always null and setting it has no effect.

      This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

      For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null. Introduced in DOM Level 2.

      public String getPrefix()
      Introduced in DOM Level 2.

      The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

    • setPrefix

      public void setPrefix(String prefix) throws DOMException
      Introduced in DOM Level 2.

      The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

      For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

      Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable. Introduced in DOM Level 2.

      Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.

      Specified by:
      setPrefix in interface Node
      Overrides:
      setPrefix in class NodeImpl
      Parameters:
      prefix - The namespace prefix of this node, or null(empty string) if it is unspecified.
      Throws:
      DOMException - INVALID_CHARACTER_ERR Raised if the specified prefix contains an invalid character.

    • getLocalName

      public String getLocalName()
      Introduced in DOM Level 2.

      Returns the local part of the qualified name of this node. For nodes created with a DOM Level 1 method, such as createElement from the Document interface, and for nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is the same as the nodeName attribute. Introduced in DOM Level 2.

      Returns the local part of the qualified name of this node.
