If you like erb, why not use it? ;)

Here's an example to get you started:

require 'erb'

def do_erb(str, erb_binding, trim_mode = '%')
  str.untaint
  erb = ERB.new(str, $SAFE, trim_mode)
  erb.result(erb_binding)
end

class Foo
  attr_accessor :greeting
end

foo = Foo.new
foo.greeting = "Hello"
template = <<EOT
<%= greeting %> from simple erb template
% 1.upto(10) do |i|
  item <%= i %>
% end
EOT

puts do_erb(template, foo.instance_eval{binding})

--- OUTPUT ---
Hello from simple erb template
  item 1
  item 2
  item 3
