XML Editor?

Hi,
With the new actionscript 3 XML class, the XML command sendAndLoad has been removed. I think this may be the cause of my script problems because I used actionscript that contained this command to edit my XML files. I was wondering if anyone could help me or point me to a tutorial for an actionscript 3 based XML editor; I’ve been use Senocular’s XML news editor as a guide. Ever since I started using Flash CS3, my news editor has stopped working. Thanks for any help.
