A code representing the type of the underlying object.
The name of this node, depending on its type.
Returns the local part of the qualified name of this node.
The namespace prefix of this node, or null if it is unspecified. When it is defined to be null, setting it has no effect, including if the node is read-only. Note that setting this attribute, when permitted, 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. Setting the prefix to null makes it unspecified, setting it to an empty string is implementation dependent. Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change. For nodes of any type other than ELEMENT and ATTRIBUTE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.
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 and ATTRIBUTE and nodes created with a DOM Level 1 method, such as Document.createElement, this is always null.
The absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI
The value of this node, depending on its type.
Returns the text content, if there's any.
Sets the text content, it there's any.
The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.
A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes.
The first child of this node. If there is no such node, this returns null.
The last child of this node. If there is no such node, this returns null.
The node immediately preceding this node. If there is no such node, this returns null.
The node immediately following this node. If there is no such node, this returns null.
The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.
A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.
Returns whether this node (if it is an element) has any attributes.
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.
Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.
Removes the child node indicated by oldChild from the list of children, and returns it.
Returns whether this node has any children.
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) and no user data. User data associated to the imported node is not carried over. However, if any UserData handlers has been specified along with the associated data these handlers will be called with the appropriate parameters before this method returns.
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.
Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.
Retrieves the object associated to a key on a this node. The object must first have been set to this node by calling setUserData with the same key.
Associate an object to a key on this node. The object can later be retrieved from this node by calling getUserData with the same key.
Compares the reference node, i.e. the node on which this method is being called, with a node, i.e. the one passed as a parameter, with regard to their position in the document and according to the document order.
Look up the prefix associated to the given namespace URI, starting from this node. The default namespace declarations are ignored by this method.
Look up the namespace URI associated to the given prefix, starting from this node.
This method checks if the specified namespaceURI is the default namespace or not.
DocumentFragment is a "lightweight" or "minimal" Document object. It is very common to want to be able to extract a portion of a document's tree or to create a new fragment of a document. Imagine implementing a user command like cut or rearranging a document by moving fragments around. It is desirable to have an object which can hold such fragments and it is quite natural to use a Node for this purpose. While it is true that a Document object could fulfill this role, a Document object can potentially be a heavyweight object, depending on the underlying implementation. What is really needed for this is a very lightweight object. DocumentFragment is such an object.
Furthermore, various operations -- such as inserting nodes as children of another Node -- may take DocumentFragment objects as arguments; this results in all the child nodes of the DocumentFragment being moved to the child list of this node.
The children of a DocumentFragment node are zero or more nodes representing the tops of any sub-trees defining the structure of the document. DocumentFragment nodes do not need to be well-formed XML documents (although they do need to follow the rules imposed upon well-formed XML parsed entities, which can have multiple top nodes). For example, a DocumentFragment might have only one child and that child node could be a Text node. Such a structure model represents neither an HTML document nor a well-formed XML document.
When a DocumentFragment is inserted into a Document (or indeed any other Node that may take children) the children of the DocumentFragment and not the DocumentFragment itself are inserted into the Node. This makes the DocumentFragment very useful when the user wishes to create nodes that are siblings; the DocumentFragment acts as the parent of these nodes so that the user can use the standard methods from the Node interface, such as Node.insertBefore and Node.appendChild.
