XMLSA for Flash MX v1.4
-----------------------------------------------------------------------------
Created by
Max Ziebell (ziebell@worldoptimizer.com)
Version History:
06/2003 - Added Mixed-Node notation
Added optional sessionID and onStartSession, onEndSession-Events
Added load, send and sendAndLoad
Added noCache with autodetection if online or local
changed dump to return the output so you can trace or assign it
Added dumpHtml
Added search
04/2003 - Added insertBefore and removeNode
removed support for Flash 5! sorry but this was causing problems!
03/2003 - Added the known methodes of XML to work with XMLSA
Now you can use: appendChild, cloneNode
Added removeChildByIndex
01/2003 - Added support for direct access of attributes
12/2002 - Added support for Flash 5 but in this case I recommend
to use XMLNitro with it.
11/2002 - First release
