I maybe am not understanding what you need, but if you are trying to do this
where you have tmp_data in memory and need to encode tmp_data
ticketing_xml << "<value><base64>#{ tmp_data }</base64></value>"
Then do
require 'base64'
ticketing_xml << "<value><base64>#{ Base64.encode64(tmp_data)
}</base64></value>"
