namespaceURI

public String namespaceURI

The namespace URI of this node, or null if it is unspecified. 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 of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Note: Per the Namespaces in XML Specification [Namespaces] an attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, it simply has no namespace.

  <div>
    Text in the first DIV.
  </div>
  <div id="DDD" class="secondClass">
    Some text in the second DIV.

</div>

JavaScript:

var main = document.getElementById('doc');

main.appendChild(main.childNodes[1]);

var output = main.lastChild.firstChild.nodeValue;

Parameters:

newChild

-

The node to add. If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node.

Return:

Node - The node added

Throws:

DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to append is one of this node's ancestors.

DOMException WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

cloneNode

public Node cloneNode(Boolean deep)

Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; (parentNode is null.). Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning an Attribute directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute (specified is true). Cloning any other type of node simply returns a copy of this node.

Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly. In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and {&link Notation} nodes is implementation dependent.

Example:

<div id="doc">
  <div>
    Text in the first DIV.
  </div>
  <div id="DDD" class="secondClass">
    Some text in the second DIV.
  </div>
  <div class="thirdClass">
    Some text and <span id="SSS">element</span> in the third DIV.
  </div>
  <div class="fourthClass">
    We can try <i>another elements</i>.
    It will be much more <b>interesting</b>.
  </div>
  <div>
    Text in the last DIV.
  </div>
</div>

JavaScript:

var main = document.getElementById('doc');

var elem = main.childNodes[3];

var returns = elem.cloneNode(true);

var output = returns.firstChild.nodeValue;

Parameters:

deep

-

If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).

Return:

Node - The duplicate node

hasAttributes

public Boolean hasAttributes()

Return:

Boolean - True if this node has any children, false otherwise.

insertBefore

public Node insertBefore(Node newChild,
                         Node refChild)

Inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children. If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed.

Example:

<div id="doc">

refChild	-	The reference node, i.e., the node before which the new node must be inserted.

Return:

Node - The node being inserted.

Throws:

DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to insert is one of this node's ancestors.

DOMException WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly or if the parent of the node being inserted is readonly.

DOMException NOT_FOUND_ERR: Raised if refChild is not a child of this node.

isSupported

public Boolean isSupported(String feature)

Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Introduced in DOM Level 2.

Example:

<div id="doc">
  <div>
    Text in the first DIV.
  </div>
  <div id="DDD" class="secondClass">
    Some text in the second DIV.
  </div>
  <div class="thirdClass">
    Some text and <span id="SSS">element</span> in the third DIV.
  </div>
  <div class="fourthClass">
    We can try <i>another elements</i>.
    It will be much more <b>interesting</b>.
  </div>
  <div>
    Text in the last DIV.
  </div>
</div>

JavaScript:

var main = document.getElementById('doc');

var output = main.isSupported('HTML', '1.0');

Parameters:

feature

-

The name of the feature to test. This is the same name which can be passed to the method DOMImplementation.hasFeature(String, String) on DOMImplementation.

Return:

Boolean - Returns true if the specified feature is supported on this node, false otherwise.

normalize

public void normalize()

Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer [XPointer] lookups) that depend on a particular document tree structure are to be used.

Note: In cases where the document contains CDATASection, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.

Modified in DOM Level 2.

Example:

<div id="doc">></div>

JavaScript:

var main = document.getElementById('doc');

var output1 = main.childNodes.length;

var textNode1 = document.createTextNode('This is some text.');

var textNode2 = document.createTextNode('This is another text.');

main.appendChild(textNode1);

main.appendChild(textNode2);

var output2 = main.childNodes.length;

main.normalize();

replaceChild

public Node replaceChild(Node newNode,
                         Node oldNode)
