public class SAXTrimmingFilter

extends SAXFilterDefaultHandler

A SAX filter that intercepts all character(...) events, trims the passed in character array and outputs ignorableWhitespace + character events as appropriate.
This filter tries not to trim character sequences within a CDATA section. It may malfunction if multiple character(...) events are fired in a row. This class should be made smarter to handle that case.
