Basic MySQL. XOR?

[dwighte.chadbourne at stopandshop.com (Dwight E Chadbourne)]

Hi.  I have two large text docs that I'm going to load into MySQL.  The
way I have my head wrapped around it is that there's two sets and I want
to see the symmetric difference.  Any tips on how to write the SQL?  I 
figure this must be a common situation and I'm just missing something 
simple.  Thanks for any tips.
