Constructor with namespace. |
Method Summary | |
Node |
appendChild(Node newChild)
Adds the node newChild to the end of the list of children
of this node. |
void |
appendChildWhileExpanding(Node child)
Append a child during node expansion. |
boolean |
areChildrenExpanded()
Are the children of this node expanded? |
Node |
cloneNode(boolean deep)
Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. |
NodeList |
getChildNodes()
A NodeList that contains all children of this node. |
Node |
getFirstChild()
The first child of this node. |
Node |
getLastChild()
The last child of this node. |
Node |
getNextSibling()
The node immediately following this node. |
int |
getNodeId()
Get the node numeric id number. |
java.lang.String |
getNodeValue()
The value of this node, depending on its type; see the table above. |
Node |
getParentNode()
The parent of this node. |
Node |
getPreviousSibling()
The node immediately preceding this node. |
LazyAttrNS |
getTemplateAttr()
Get the template for this node. |
LazyNode |
getTemplateNode()
Get the template node as a LazyNode. |
java.lang.String |
getValue()
On retrieval, the value of the attribute is returned as a string. |
boolean |
hasChildNodes()
Returns whether this node has any children. |
Node |
insertBefore(Node newChild,
Node refChild)
Inserts the node newChild before the existing child node
refChild . |
boolean |
isParentExpanded()
Is the parent of this node expanded? |
boolean |
isTemplateNode()
Check if this node is a template node. |
void |
makeTemplateNode(int nodeId)
|
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. |
Node |
removeChild(Node oldChild)
Removes the child node indicated by oldChild from the list
of children, and returns it. |
Node |
replaceChild(Node newChild,
Node oldChild)
Replaces the child node oldChild with newChild
in the list of children, and returns the oldChild node. |
void |
setChildrenExpanded()
Flag the children as being expanded. |
void |
setNodeValue(java.lang.String nodeValue)
Implicit in the rerouting of getNodeValue to getValue is the need to redefine setNodeValue, for symmetry's sake. |
void |
setParentExpanded()
Flag the parent as being expanded. |
void |
setParentWhileExpanding(Node parent)
Set the parent of this node during expansion. |
void |
setValue(java.lang.String value)
The DOM doesn't clearly define what setValue(null) means. |
LazyNode |
templateClone(Document ownerDocument)
Create a new node, using this node as the template. |
java.lang.String |
toString()
Return string for debugging. |

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.

"normal" form where only structure (e.g., elements, comments,

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 lookups) that depend on a particular document tree
structure are to be used.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.
