public short getNodeType()
getNodeType in interface org.w3c.dom.Nodepublic void normalize()
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 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.

which is not used with any Document yet, this is
null.

parentNode is null.).
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.
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 org.w3c.dom.Nodedeep - 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).

there are no children, this is a NodeList containing no
nodes.

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