whiteSpace

• Determines what the application should do with white space found in the content

• Three possible values:

  • preserve: The white space in the input document is left unchanged

  • replace: Each tab, carriage return and linefeed is replaced with a single space.

  • collapse: Each tab, carriage return and linefeed is replaced with a single space. Furthermore, after this replacement is performed, all runs of multiple spaces are condensed to a single space. Leading and trailing white space is deleted.

• No effect on validation

• Applies to string, normalizedString and token type items

• Per XML 1.0, white space in attributes is normalized irregardless of the schema

• For example, to say that white space should be collapsed in all names and titles:
