appendChild
public Node appendChild(Node newChild)
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.
- appendChild in interface Node
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
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 or this node
itself, or if this node is of type Document
and the
DOM application attempts to append a second
DocumentType
or Element
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 is readonly or
if the previous parent of the node being inserted is readonly.
NOT_SUPPORTED_ERR: if the newChild
node is a child
of the Document
node, this exception might be raised
if the DOM implementation doesn't support the removal of the
DocumentType
child or Element
child.
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
) 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.
- cloneNode in interface Node
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
).
compareDocumentPosition
public short compareDocumentPosition(Node other)
throws DOMException
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.
- compareDocumentPosition in interface Node
other
- The node to compare against the reference node.
- Returns how the node is positioned relatively to the reference
node.
DOMException
- NOT_SUPPORTED_ERR: when the compared nodes are from different DOM
implementations that do not coordinate to return consistent
implementation-specific results.
getBaseURI
public String getBaseURI()
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.
- getBaseURI in interface Node
getChildNodes
public NodeList getChildNodes()
A NodeList
that contains all children of this node. If
there are no children, this is a NodeList
containing no
nodes.
- getChildNodes in interface Node
getFeature
public Object getFeature(String feature,
String version)
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.
- getFeature in interface Node
feature
- The name of the feature requested. Note that any plus
sign "+" prepended to the name of the feature will be ignored since
it is not significant in the context of this method.version
- This is the version number of the feature to test.
- Returns an object which implements the specialized APIs of
the specified feature and version, if any, or
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.
getLocalName
public String getLocalName()
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
.
- getLocalName in interface Node
getNamespaceURI
public String getNamespaceURI()
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.
- getNamespaceURI in interface Node
getNodeType
public short getNodeType()
A code representing the type of the underlying object, as defined above.
- getNodeType in interface Node
getNodeValue
public String getNodeValue()
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.
- getNodeValue in interface Node
DOMException
- DOMSTRING_SIZE_ERR: Raised when it would return more characters than
fit in a DOMString
variable on the implementation
platform.
getOwnerDocument
public Document getOwnerDocument()
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
.
- getOwnerDocument in interface Node
getParentNode
public Node getParentNode()
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
.
- getParentNode in interface Node
getPrefix
public String getPrefix()
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
.
- getPrefix in interface Node
getTextContent
public String getTextContent()
throws DOMException
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. |
TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE,
PROCESSING_INSTRUCTION_NODE | nodeValue |
DOCUMENT_NODE,
DOCUMENT_TYPE_NODE, NOTATION_NODE | null |
- getTextContent in interface Node
DOMException
- DOMSTRING_SIZE_ERR: Raised when it would return more characters than
fit in a DOMString
variable on the implementation
platform.
getUserData
public Object getUserData(String key)
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.
- getUserData in interface Node
key
- The key the object is associated to.
- Returns the
DOMUserData
associated to the given
key on this node, or null
if there was none.
hasAttributes
public boolean hasAttributes()
Returns whether this node (if it is an element) has any attributes.
- hasAttributes in interface Node
- Returns
true
if this node has any attributes,
false
otherwise.
hasChildNodes
public boolean hasChildNodes()
Returns whether this node has any children.
- hasChildNodes in interface Node
- Returns
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.
Note: Inserting a node before itself is implementation
dependent.
- insertBefore in interface Node
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 newChild
node, or if
the node to insert is one of this node's ancestors or this node
itself, or if this node is of type Document
and the
DOM application attempts to insert a second
DocumentType
or Element
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 is readonly or
if the parent of the node being inserted is readonly.
NOT_FOUND_ERR: Raised if refChild
is not a child of
this node.
NOT_SUPPORTED_ERR: if this node is of type Document
,
this exception might be raised if the DOM implementation doesn't
support the insertion of a DocumentType
or
Element
node.
isDefaultNamespace
public boolean isDefaultNamespace(String namespaceURI)
This method checks if the specified namespaceURI
is the
default namespace or not.
- isDefaultNamespace in interface Node
namespaceURI
- The namespace URI to look for.
- Returns
true
if the specified
namespaceURI
is the default namespace,
false
otherwise.
isEqualNode
public boolean isEqualNode(Node arg)
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:
- The two nodes are of the same type.
- The following string
attributes are equal:
nodeName
, localName
,
namespaceURI
, prefix
, nodeValue
. This is: they are both null
, or they have the same
length and are character for character identical.
- The
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.
- The
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.
For two
DocumentType
nodes to be equal, the following
conditions must also be satisfied:
- The following string attributes
are equal:
publicId
, systemId
,
internalSubset
.
- The
entities
NamedNodeMaps
are equal.
- The
notations
NamedNodeMaps
are equal.
On the other hand, the following do not affect equality: the
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.
- isEqualNode in interface Node
arg
- The node to compare equality with.
- Returns
true
if the nodes are equal,
false
otherwise.
isSameNode
public boolean isSameNode(Node other)
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.
- isSameNode in interface Node
other
- The node to test against.
- Returns
true
if the nodes are the same,
false
otherwise.
isSupported
public boolean isSupported(String feature,
String version)
Tests whether the DOM implementation implements a specific feature and
that feature is supported by this node, as specified in .
- isSupported in interface Node
feature
- The name of the feature to test.version
- This is the version number of the feature to test.
- Returns
true
if the specified feature is
supported on this node, false
otherwise.
lookupNamespaceURI
public String lookupNamespaceURI(String prefix)
Look up the namespace URI associated to the given prefix, starting from
this node.
See for details on the algorithm used by this method.
- lookupNamespaceURI in interface Node
prefix
- The prefix to look for. If this parameter is
null
, the method will return the default namespace URI
if any.
- Returns the associated namespace URI or
null
if
none is found.
lookupPrefix
public String lookupPrefix(String namespaceURI)
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.
- lookupPrefix in interface Node
namespaceURI
- The namespace URI to look for.
- Returns an associated namespace prefix if found or
null
if none is found. If more than one prefix are
associated to the namespace prefix, the returned namespace prefix
is implementation dependent.
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. 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.
- normalize in interface Node
removeChild
public Node removeChild(Node oldChild)
Removes the child node indicated by oldChild
from the list
of children, and returns it.
- removeChild in interface Node
oldChild
- The node being removed.
DOMException
- NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if oldChild
is not a child of
this node.
NOT_SUPPORTED_ERR: if this node is of type Document
,
this exception might be raised if the DOM implementation doesn't
support the removal of the DocumentType
child or the
Element
child.
replaceChild
public Node replaceChild(Node newChild,
Node oldChild)
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.
- replaceChild in interface Node
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
this node.
NOT_SUPPORTED_ERR: if this node is of type Document
,
this exception might be raised if the DOM implementation doesn't
support the replacement of the DocumentType
child or
Element
child.
setNodeValue
public void setNodeValue(String nodeValue)
throws DOMException
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.
- setNodeValue in interface Node
DOMException
- NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly and if
it is not defined to be null
.
setPrefix
public void setPrefix(String prefix)
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
.
- setPrefix in interface Node
DOMException
- INVALID_CHARACTER_ERR: Raised if the specified prefix contains an
illegal character according to the XML version in use specified in
the Document.xmlVersion
attribute.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix
is
malformed per the Namespaces in XML specification, 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" [XML Namespaces]
.
setTextContent
public void setTextContent(String textContent)
throws DOMException
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
