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.
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.

nodes are
specified. And, cloning Document

public void normalize()
Node
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.
