What type of system are you onlining on? If you are onling on an FCP system you dont need to export XML, just use Media Manager to create an offline copy of your sequence in the codec of your choice, then recapture.
Realisticially, there is nothing that does what you want as far as effects if you are moving to a different platform. Automatic Duck does a great job when moving to Avid, but its not a “Total Conform”.
