Subject: Net::FTP puttextfile question

I'm trying to use the Net::FTP class to send a text file to my FTP
server, but I don't have an actual text file to send.  Instead I want
to send it a multi-line string as my "file".  (I'm using Builder to
generate an XML file and I don't want to have to physically save it to
a file before sending it.)

The Net::FTP class has a method called puttextfile that seems to be
defined like this:

 def puttextfile(localfile, remotefile = File.basename(localfile),
&block)

but I don't have a local filename to provide.  Is there anything I can
use that would substitute for one?

I tried to use a StringIO object, hoping to use that as my
"localfile":

s = StringIO.new(xml_data)

but when I try to send it like this:

Net::FTP.open("domain.com", "username", "secret") do |ftp|
  ftp.puttextfile(s, '\data\file.xml"')
end

I get this error:

TypeError: can't convert StringIO into String
        from c:/ruby/lib/ruby/1.8/net/ftp.rb:571:in `open'
        from c:/ruby/lib/ruby/1.8/net/ftp.rb:571:in `puttextfile'
        from (irb):33
        from c:/ruby/lib/ruby/1.8/net/ftp.rb:115:in `open'
        from (irb):32

Obviously it wants a filename, and I'm giving it the actual IO object
instead.  .NET had the concept of IO streams, and I was hoping to use
something like that here, but I can't figure out how.

Any ideas?

Thanks!
