generating CReturn in xml file

Josselin

I am generating an xml output file from my rails app to be read in
Flash.. working fine as long as I don't have to insert a CR in a string
to be understood by Flash

Flash can understand the CR if the character 
 is embedded (ASCII
code for CR)

so if I have a string like "Announce 14
at 04/04/2007", it will
display correctly into my Flash object as

Announce 13
at 04/04/2007

my problem is how to generate the string, I tried :

name_label = "Announce " + proposition.id.to_s + "\nat " +
post.created_at.utc.strftime("%d/%b/%Y")
but it's not working
I also tried ....
name_label = "Announce " + proposition.id.to_s + "
at " +
post.created_at.utc.strftime("%d/%b/%Y")
not working
.... how can I put this character sequence as it ?

thanks for your help

"\r" is character 13. "\n" is character 10.

$ irb1.8
irb(main):001:0> "\r"[0]
=> 13
