I found a solution based on an idea posted at

 
http://marsorange.com/articles/2006/07/17/of-mogrify-ruby-tempfile-dynam
ic-class-definitions

which allowed me to use most of Tempfile functionality with only
providing
minimal own code:

require 'tempfile'
class XMLTempfile <Tempfile
  def make_tmpname(basename, n)
    sprintf('%s%d-%d.xml', basename, $$, n)
  end
end

....

    file=XMLTempfile.new('.tempreq',TFW_REQDIR)
    file << '.....'
    result=file.path
    file.close
