Thanks. Yeh, I'm doing that actually. Obviously, this is just a snipped 
of my code. I do this at the end of the script:

File.open("F:/workflows/text/in/lobbying/temp/newfile.sgm", "w") { |f| 
f.print xmlfile }

But, this little code line above is just one of many code lines just 
like it. It's just converting one thing and the others are converting 
other things. And, . . ., they're all working!
