If you want to use erb, then you can do something like that.

require 'erb'

erb=ERB.new <<-'DONE'
<% 5.times do %>
this text is repeated
<% end %>
DONE
form=erb.result(binding)

Be warned that you have to place the commands correctly to avoid getting 
extra newlines. (This is mostly intended for HTML templating, where 
newlines don't matter.)
