defaulted attributes, but this method does not copy any text it

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

sufficient, since XPointers do not differentiate between
Text

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 theNode
interface expose methods for dealing with children, not all objects implementing theNode
interface may have children. For example,Text
nodes may not have children, and adding children to such nodes results in aDOMException
being raised. The attributesnodeName
,nodeValue
andattributes
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 specificnodeType
(e.g.,nodeValue
for anElement
orattributes
for aComment
), this returnsnull
. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information. The values ofnodeName
,nodeValue
, andattributes
vary according to the node type as follows:"#cdata-section"
"#comment"
"#document"
"#document-fragment"
"#text"
