true
if this node has any children,
false
otherwise.public 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.
