This should get you started, i.e. you should be able to easily modify  
it to do what you want it to, even if you don't know much ruby.  
Create a command with input selected text with fallback line, output  
replace selected text (or possibly insert as snippet if you want to  
do something more clever) and text:

#!/usr/bin/env ruby
#
print "<ul>\n"
STDIN.read.each_line { |x|
print "\t<li>\n\t\t<p>#{x.chomp}</p>\n\t</li>\n"
   }
print "</ul>\n"


I hope this is (at least relatively) clear and you should be able to  
modify it to do stuff. the syntax #{x.chomp} which might seem  
familiar tells Ruby: "I know you are inside a string now, but execute  
the thing in the {} as a ruby program and put its output in the  
string right here". x.chomp returns the string x with the possible  
newline removed.
