The
Node
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
Node
interface expose
methods for dealing with children, not all objects implementing the
Node
interface may have children. For example,
Text
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
Element
or
attributes
for a
Comment
), 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 |
---|---|---|---|

HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not
allow children of the type of the

the node to append is one of this node's ancestors or this node
itself, or if this node is of type

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
UserDataHandlers
has been specified along with the
associated data these handlers will be called with the appropriate
parameters before this method returns.
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 children it
contains unless it is a deep clone. This includes text contained in
an the
Element
since the text is contained in a child
Text
node. Cloning an
Attr
directly, as
opposed to be cloned as part of an
Element
cloning
operation, returns a specified attribute (
specified
is
true
). Cloning an
Attr
always clones its
children, since they represent its value, no matter whether this is a
deep clone or not. Cloning an
EntityReference
automatically constructs its subtree if a corresponding
Entity
is available, no matter whether this is a deep
clone or not. 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
Notation
nodes is implementation dependent.

A
NamedNodeMap
containing the attributes of this node (if
it is an
Element
) or
null
otherwise.
The absolute base URI of this node or
null
if the
implementation wasn't able to obtain an absolute URI. This value is
computed as described in . However, when the
Document
supports the feature "HTML" [
DOM Level 2 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
Document
interface otherwise.
A
NodeList
that contains all children of this node. If
there are no children, this is a
NodeList
containing no
nodes.
This method returns a specialized object which implements the
specialized APIs of the specified feature and version, as specified
in . The specialized object may also be obtained by using
binding-specific casting methods but is not necessarily expected to,
as discussed in . This method also allow the implementation to
provide specialized objects which do not support the
Node
interface.

---|---|
version | This is the version number of the feature to test. |
null
if
there is no object which implements interfaces associated with that
feature. If the
DOMObject
returned by this method
implements the
Node
interface, it must delegate to the
primary core
Node
and not return results inconsistent
with the primary core
Node
such as attributes,
childNodes, etc.
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
.
Returns the local part of the qualified name of this node.
For nodes of any type other than
ELEMENT_NODE
and
ATTRIBUTE_NODE
and nodes created with a DOM Level 1
method, such as
Document.createElement()
, this is always
null
.
The namespace URI of this node, or
null
if it is
unspecified (see ).
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
Document.createElement()
, this is always
null
.
Note: Per the Namespaces in XML Specification [ XML 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.
The node immediately following this node. If there is no such node,
this returns
null
.
The name of this node, depending on its type; see the table above.
A code representing the type of the underlying object, as defined above.
The value of this node, depending on its type; see the table above.
When it is defined to be
null
, setting it has no effect,
including if the node is read-only.
DOMException |
DOMSTRING_SIZE_ERR: Raised when it would return more characters than
fit in a
DOMString
variable on the implementation
platform.

---|
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
.
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
.
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_NODE
and
ATTRIBUTE_NODE
and nodes created with a DOM Level 1
method, such as
createElement
from the
Document
interface, this is always
null
.
The node immediately preceding this node. If there is no such node,
this returns
null
.
This attribute returns the text content of this node and its
descendants. When it is defined to be
null
, setting it
has no effect. On setting, any possible children this node may have
are removed and, if it the new string is not empty or
null
, replaced by a single
Text
node
containing the string this attribute is set to.
On getting, 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 (see the attribute
Text.isElementContentWhitespace
). Similarly, on setting,
no parsing is performed either, the input string is taken as pure
textual content.
The string returned is made of the text content of this node
depending on its type, as defined below:
Node type | Content |
---|---|
ELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE |
concatenation of the
textContent
attribute value of every child node, excluding COMMENT_NODE and
PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the
node has no children.

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.
Note: Inserting a node before itself is implementation dependent.
newChild | The node to insert. |

refChild | The reference node, i.e., the node before which the new node must be inserted. |
DOMException |
HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not
allow children of the type of the

default namespace or not.
namespaceURI | The namespace URI to look for. |

Tests whether two nodes are equal.
This method tests for equality of nodes, not sameness (i.e.,
whether the two nodes are references to the same object) which can be
tested with
Node.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:
nodeName
,
localName
,
namespaceURI
,
prefix
,
nodeValue
. This is: they are both
null
, or they have the same
length and are character for character identical.
attributes
NamedNodeMaps
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.
childNodes
NodeLists
are equal.
This is: they are both
null
, or they have the same
length and contain equal nodes at the same index. Note that
normalization can affect equality; to avoid this, nodes should be
normalized before being compared.
DocumentType
nodes to be equal, the following
conditions must also be satisfied:
publicId
,
systemId
,
internalSubset
.
entities
NamedNodeMaps
are equal.
notations
NamedNodeMaps
are equal.
ownerDocument
,
baseURI
, and
parentNode
attributes, the
specified
attribute for
Attr
nodes, the
schemaTypeInfo
attribute for
Attr
and
Element
nodes, the
Text.isElementContentWhitespace
attribute for
Text
nodes, as well as any user data or event listeners
registered on the nodes.
Note: As a general rule, anything not mentioned in the description above is not significant in consideration of equality checking. Note that future versions of this specification may take into account more attributes and implementations conform to this specification are expected to be updated accordingly.
arg | The node to compare equality with. |
---|
true
if the nodes are equal,
false
otherwise.
Returns whether this node is the same node as the given one.
This method provides a way to determine whether two
Node
references returned by the implementation reference
the same object. When two
Node
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.
other | The node to test against. |
---|
true
if the nodes are the same,
false
otherwise.
Tests whether the DOM implementation implements a specific feature and that feature is supported by this node, as specified in .
feature | The name of the feature to test. |
---|---|
version | This is the version number of the feature to test. |
true
if the specified feature is
supported on this node,
false
otherwise.
Look up the namespace URI associated to the given prefix, starting from
this node.
See for details on the algorithm used by this method.
prefix |
The prefix to look for. If this parameter is
null
, the method will return the default namespace URI
if any.
|
---|
null
if
none is found.
Look up the prefix associated to the given namespace URI, starting from
this node. The default namespace declarations are ignored by this
method.
See for details on the algorithm used by this method.
namespaceURI | The namespace URI to look for. |
---|
null
if none is found. If more than one prefix are
associated to the namespace prefix, the returned namespace prefix
is implementation dependent.
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. If the parameter "normalize-characters" of the
DOMConfiguration
object attached to the
Node.ownerDocument
is
true
, this method
will also fully normalize the characters of the
Text
nodes.
Note:
In cases where the document contains
CDATASections
, the normalize operation alone may not be
sufficient, since XPointers do not differentiate between
Text
nodes and
CDATASection
nodes.
Removes the child node indicated by
oldChild
from the list
of children, and returns it.
oldChild | The node being removed. |

support the removal of the
DocumentType
child or the
Element
child.

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.
Note: Replacing a node with itself is implementation dependent.
newChild | The new node to put in the child list. |
---|---|
oldChild | The node being replaced in the list. |
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 put in is one of this node's ancestors or this node
itself, or if this node is of type
Document
and the
result of the replacement operation would add a second
DocumentType
or
Element
on the
Document
node.
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 parent of the new node is readonly. NOT_FOUND_ERR: Raised if
oldChild
is not a child of

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_NODE
and
ATTRIBUTE_NODE
and nodes created with a DOM Level 1
method, such as
createElement
from the

This attribute returns the text content of this node and its
descendants. When it is defined to be
null
, setting it
has no effect. On setting, any possible children this node may have
are removed and, if it the new string is not empty or
null
, replaced by a single
Text
node
containing the string this attribute is set to.
On getting, 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 (see the attribute
Text.isElementContentWhitespace
). Similarly, on setting,
no parsing is performed either, the input string is taken as pure
textual content.
The string returned is made of the text content of this node
depending on its type, as defined below:
Node type | Content |
---|---|
ELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE |
concatenation of the
textContent
attribute value of every child node, excluding COMMENT_NODE and
PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the
node has no children.
