XML DOM normalize() Method
Definition and Usage
normalize()
The method puts all text nodes under the node (including attribute nodes) into a paradigm, in which only the structure (such as elements, comments, processing instructions, CDATA sections, and entity references) separates text nodes, that is, neither adjacent text nodes nor empty text nodes.
The paradigm is very useful for operations that require a specific document tree structure, and ensures that the XML DOM view of the document is the same when saved and reloaded.
