How about something like this:

$ cat for_xml.csv
filename
one
two
three
$ cat csv2xml.rb
#!/usr/bin/env ruby -wKU

require "rubygems"
require "faster_csv"

FCSV.foreach(ARGV.shift, :headers => true) do |row|
   File.open(row["filename"] + ".xml", "w") do |f|
     # create XML data here...
   end
end
$ ruby csv2xml.rb for_xml.csv
$ ls *.xml
one.xml		three.xml	two.xml

Hope that helps.
