A nonbreaking space (  , hexadecimal  ) is not considered white space because that content is not to be interpreted as an allowable place to break to a new line. In a Web environment, practical uses for the nonbreaking space are limited; generally, you want the browser to wrap long lines.

You can control white space output in an XML document by using Document Object Model (DOM) or XSL Transformation (XSLT) functionality.
