XML DOM normalize() method

Definition and Usage

normalize() The method puts all text nodes under the node (including attribute nodes) into a schema, in which only 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 schema 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.
