Detailed Description

The DOMNode interface is the primary datatype for the entire Document Object Model.

It represents a single node in the document tree. While all objects implementing the DOMNode interface expose methods for dealing with children, not all objects implementing the DOMNode interface may have children. For example, DOMText nodes may not have children, and adding children to such nodes results in a DOMException being raised.

The attributes nodeName, nodeValue and attributes are included as a mechanism to get at node information without casting down to the specific derived interface. In cases where there is no obvious mapping of these attributes for a specific nodeType (e.g., nodeValue for an DOMElement or attributes for a DOMComment ), this returns null. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information.

The values of nodeName, nodeValue, and attributes vary according to the node type as follows:

Interface	nodeName	nodeValue	attributes
DOMAttr	name of attribute	value of attribute	null
DOMCDATASection	"#cdata-section"	content of the CDATA Section	null
DOMComment	"#comment"	content of the comment	null
DOMDocument	"#document"	null	null
DOMDocumentFragment	"#document-fragment"	null	null
DOMDocumentType	document type name	null	null
DOMElement	tag name	null	NamedNodeMap
DOMEntity	entity name	null	null
DOMEntityReference	name of entity referenced	null	null
DOMNotation	notation name	null	null
DOMProcessingInstruction	target	entire content excluding the target	null
DOMText	"#text"	content of the text node	null

Member Function Documentation

virtual DOMNode* DOMNode::appendChild ( DOMNode * newChild )

pure virtual

Adds the node newChild to the end of the list of children of this node.

If the newChild is already in the tree, it is first removed.

Parameters

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

Returns: The node added.

Exceptions

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.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the node being appended is readonly.

Since: DOM Level 1

virtual DOMNode* DOMNode::cloneNode ( bool deep ) const

pure virtual

Returns a duplicate of this node.

This function serves as a generic copy constructor for nodes.

The duplicate node has no parent ( parentNode returns null.).
Cloning an DOMElement 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 DOMText node. Cloning any other type of node simply returns a copy of this node.

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 `DOMElement`).

Returns: The duplicate node.

Since: DOM Level 1

virtual short DOMNode::compareDocumentPosition ( const DOMNode * other ) const

pure virtual

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.

Parameters

other The node to compare against this node.

Returns: Returns how the given node is positioned relatively to this node.

Since: DOM Level 3

virtual DOMNamedNodeMap* DOMNode::getAttributes ( ) const

pure virtual

Gets a DOMNamedNodeMap containing the attributes of this node (if it is an DOMElement) or null otherwise.

Since: DOM Level 1

virtual const XMLCh* DOMNode::getBaseURI ( ) const

pure virtual

The absolute base URI of this node or null if undefined.

This value is computed according to . However, when the DOMDocument supports the feature "HTML" , the base URI is computed using first the value of the href attribute of the HTML BASE element if any, and the value of the documentURI attribute from the DOMDocument interface otherwise.

When the node is an DOMElement, a DOMDocument or a a DOMProcessingInstruction, this attribute represents the properties [base URI] defined in . When the node is a DOMNotation, an DOMEntity, or an DOMEntityReference, this attribute represents the properties [declaration base URI].

Since: DOM Level 3

virtual DOMNodeList* DOMNode::getChildNodes ( ) const

pure virtual

Gets a DOMNodeList that contains all children of this node.

If there are no children, this is a DOMNodeList containing no nodes. The content of the returned DOMNodeList is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the DOMNodeList accessors; it is not a static snapshot of the content of the node. This is true for every DOMNodeList, including the ones returned by the getElementsByTagName method.

Since: DOM Level 1

virtual void* DOMNode::getFeature	(	const XMLCh *	feature,
		const XMLCh *	version
	)		const

pure virtual

This method makes available a DOMNode's specialized interface.

Parameters

feature	The name of the feature requested (case-insensitive).
version	The version of the feature requested.

Returns: Returns an alternate DOMNode which implements the specialized APIs of the specified feature, if any, or null if there is no alternate DOMNode which implements interfaces associated with that feature. Any alternate DOMNode returned by this method must delegate to the primary core DOMNode and not return results inconsistent with the primary core DOMNode such as key, attributes, childNodes, etc.

Since: DOM Level 3

virtual DOMNode* DOMNode::getFirstChild ( ) const

pure virtual

Gets the first child of this node.

If there is no such node, this returns null.

Since: DOM Level 1

pure virtual

Gets the last child of this node.

If there is no such node, this returns null.

Since: DOM Level 1

virtual const XMLCh* DOMNode::getLocalName ( ) const

pure virtual

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 DOMDocument interface, it is null.

Since: DOM Level 2

virtual const XMLCh* DOMNode::getNamespaceURI ( ) const

pure virtual

Get 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 DOMDocument interface, this is always null.

Since: DOM Level 2

virtual DOMNode* DOMNode::getNextSibling ( ) const

This is also the DOMDocument object used to create new nodes. When this node is a DOMDocument or a DOMDocumentType which is not used with any DOMDocument yet, this is null.

Since: DOM Level 1

virtual DOMNode* DOMNode::getParentNode ( ) const

pure virtual

Gets the parent of this node.

All nodes, except DOMDocument, DOMDocumentFragment, and DOMAttr 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, a null DOMNode is returned.

pure virtual

Get the namespace prefix of this node, or null if it is unspecified.

Since: DOM Level 2

virtual DOMNode* DOMNode::getPreviousSibling ( ) const

pure virtual

Gets the node immediately preceding this node.

If there is no such node, this returns null.

Since: DOM Level 1

virtual const XMLCh* DOMNode::getTextContent ( ) const

pure virtual

This attribute returns the text content of this node and its descendants.

No serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed and the returned string does not contain the white spaces in element content.

The string returned is made of the text content of this node depending on its type, as defined below:

Node type	Content

Returns: true if this node has any attributes, false otherwise.

Since: DOM Level 2

virtual bool DOMNode::hasChildNodes ( ) const

pure virtual

This is a convenience method to allow easy determination of whether a node has any children.

Returns: true if the node has any children, false if the node has no children.

Since: DOM Level 1

virtual DOMNode* DOMNode::insertBefore	(	DOMNode *	newChild,
		DOMNode *	refChild
	)

pure virtual

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 DOMDocumentFragment 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. Note that a DOMNode that has never been assigned to refer to an actual node is == null.

Parameters

newChild	The node to insert.
refChild	The reference node, i.e., the node before which the new node must be inserted.

Returns: The node being inserted.

Exceptions

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.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the node being inserted is readonly.

Since: DOM Level 1

virtual bool DOMNode::isDefaultNamespace ( const XMLCh * namespaceURI ) const

pure virtual

This method checks if the specified namespaceURI is the default namespace or not.

Parameters

namespaceURI The namespace URI to look for.

Returns: true if the specified namespaceURI is the default namespace, false otherwise.

Since: DOM Level 3

virtual bool DOMNode::isEqualNode ( const DOMNode * arg ) const

pure virtual

Tests whether two nodes are equal.

This method tests for equality of nodes, not sameness (i.e., whether the two nodes are pointers to the same object) which can be tested with DOMNode::isSameNode. All nodes that are the same will also be equal, though the reverse may not be true.
Two nodes are equal if and only if the following conditions are satisfied: The two nodes are of the same type.The following string attributes are equal: nodeName, localName, namespaceURI, prefix, nodeValue , baseURI. This is: they are both null, or they have the same length and are character for character identical. The attributes DOMNamedNodeMaps are equal. This is: they are both null, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.The childNodes DOMNodeLists are equal. This is: they are both null, or they have the same length and contain equal nodes at the same index. This is true for DOMAttr nodes as for any other type of node. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.
For two DOMDocumentType nodes to be equal, the following conditions must also be satisfied: The following string attributes are equal: publicId, systemId, internalSubset.The entities DOMNamedNodeMaps are equal.The notations DOMNamedNodeMaps are equal.
On the other hand, the following do not affect equality: the ownerDocument attribute, the specified attribute for DOMAttr nodes, the isWhitespaceInElementContent attribute for DOMText nodes, as well as any user data or event listeners registered on the nodes.

Parameters

arg	The node to compare equality with.

Returns: If the nodes, and possibly subtrees are equal, true otherwise false.

Since: DOM Level 3

virtual bool DOMNode::isSameNode ( const DOMNode * other ) const

pure virtual

Returns whether this node is the same node as the given one.

This method provides a way to determine whether two DOMNode references returned by the implementation reference the same object. When two DOMNode references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.

Parameters

other The node to test against.

Returns: Returns true if the nodes are the same, false otherwise.

Since: DOM Level 3

virtual bool DOMNode::isSupported	(	const XMLCh *	feature,
		const XMLCh *	version
	)		const

pure virtual

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

Parameters

feature	The string of the feature to test. This is the same name as what can be passed to the method `hasFeature` on `DOMImplementation`.
version	This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return `true`.

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

Since: DOM Level 2

virtual const XMLCh* DOMNode::lookupNamespaceURI ( const XMLCh * prefix ) const

pure virtual

Look up the namespace URI associated to the given prefix, starting from this node.

Parameters

prefix The prefix to look for. If this parameter is null, the method will return the default namespace URI if any.

Returns: Returns the associated namespace URI or null if none is found.

Since: DOM Level 3

virtual const XMLCh* DOMNode::lookupPrefix ( const XMLCh * namespaceURI ) const

pure virtual

Look up the prefix associated to the given namespace URI, starting from this node.

The default namespace declarations are ignored by this method.

Parameters

namespaceURI The namespace URI to look for.

Returns: Returns an associated namespace prefix if found, null if none is found. If more than one prefix are associated to the namespace prefix, the returned namespace prefix is implementation dependent.

Since: DOM Level 3

virtual void DOMNode::normalize ( )

pure virtual

Puts all DOMText nodes in the full depth of the sub-tree underneath this DOMNode, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates DOMText nodes, i.e., there are neither adjacent DOMText nodes nor empty DOMText 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 lookups) that depend on a particular document tree structure are to be used.

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

Since: DOM Level 2

virtual void DOMNode::release ( )

pure virtual

Called to indicate that this Node (and its associated children) is no longer in use and that the implementation may relinquish any resources associated with it and its associated children.

If this is a document, any nodes it owns (created by DOMDocument::createXXXX()) are also released.

Access to a released object will lead to unexpected result.

Exceptions

DOMException INVALID_ACCESS_ERR: Raised if this Node has a parent and thus should not be released yet.

virtual DOMNode* DOMNode::removeChild ( DOMNode * oldChild )

pure virtual

Removes the child node indicated by oldChild from the list of children, and returns it.

Parameters

oldChild The node being removed.

Returns: The node removed.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if oldChild is not a child of this node.

Since: DOM Level 1

virtual DOMNode* DOMNode::replaceChild	(	DOMNode *	newChild,
		DOMNode *	oldChild
	)

pure virtual

Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.

If newChild is a DOMDocumentFragment object, oldChild is replaced by all of the DOMDocumentFragment children, which are inserted in the same order.

If the newChild is already in the tree, it is first removed.

Parameters

newChild	The new node to put in the child list.
oldChild	The node being replaced in the list.

Returns: The node replaced.

Exceptions

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 it the node to put in is one of this node's ancestors.
WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node or the new node is readonly.
NOT_FOUND_ERR: Raised if oldChild is not a child of this node.

Since: DOM Level 1

virtual void DOMNode::setNodeValue ( const XMLCh * nodeValue )

pure virtual

Sets the value of the node.

Any node which can have a nodeValue will also accept requests to set it to a string. The exact response to this varies from node to node – Attribute, for example, stores its values in its children and has to replace them with a new Text holding the replacement value.

For most types of Node, value is null and attempting to set it will throw DOMException(NO_MODIFICATION_ALLOWED_ERR). This will also be thrown if the node is read-only.

See also: getNodeValue

Since: DOM Level 1

virtual void DOMNode::setPrefix ( const XMLCh * prefix )

pure virtual

Set the namespace prefix of this node.

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 DOMElement and DOMAttr interfaces, when applicable.

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.

Parameters

prefix The prefix of this node.

Exceptions

DOMException INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix is malformed, if the namespaceURI of this node is null, if the specified prefix is "xml" and the namespaceURI of this node is different from "http://www.w3.org/XML/1998/namespace", if this node is an attribute and the specified prefix is "xmlns" and the namespaceURI of this node is different from "http://www.w3.org/2000/xmlns/", or if this node is an attribute and the qualifiedName of this node is "xmlns".

Since: DOM Level 2

virtual void DOMNode::setTextContent ( const XMLCh * textContent )

pure virtual

This attribute removes any possible children this node may have and, if the new string is not empty or null, replaced by a single DOMText node containing the string this attribute is set to.

No parsing is performed, the input string is taken as pure textual content.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

See also: getTextContent

Since: DOM Level 3

virtual void* DOMNode::setUserData	(	const XMLCh *	key,
		void *	data,
		DOMUserDataHandler *	handler
	)

pure virtual

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.

Deletion of the user data remains the responsibility of the application program; it will not be automatically deleted when the nodes themselves are reclaimed.

Both the parameter data and the returned object are void pointer, it is applications' responsibility to keep track of their original type. Casting them to the wrong type may result unexpected behavior.

Parameters

key	The key to associate the object to.
data	The object to associate to the given key, or `null` to remove any existing association to that key.
handler	The handler to associate to that key, or `null`.

Returns: Returns the void* object previously associated to the given key on this node, or null if there was none.
