I further suggest studying the command that does this trick. Here is  
the code for it, with comments removed:

#!/usr/bin/env ruby
single_no_arg = /^(?:br|hr)$/i
single        = /^(?:img|meta|link|input|base|area|col|frame|param)$/i
print case tag = STDIN.read
   when single_no_arg then "<#{tag} />"
   when single then        "<#{tag} $1/>"
   when '' then            "<${1:p}>$2</${1/\\s.*//}>"
   else                    "<#{tag}>$1</#{tag.strip[/^\S+/]}>"
end

It is set to output "Insert as snippet". This means that the various  
strings to be printed that we see above should be interpreted as  
snippets. The one relevant for us here is:
"<${1:p}>$2</${1/\\s.*//}>"

when that snippet is in action, anything you type in the <${1:p}>  
part  gets copied at the closing snippet as well, except that  
everything from the first space and no is substituted by nothing  
(that's what the ${1/\\s.*//} does, see http://macromates.com/ 
textmate/manual/snippets#transformations ).

So you would do ctrl+<, followed by typing 'span' , then space, and  
then the class stuff. On the closing tag only the 'span' part will  
appear. When you are ready to type the things in the tag, press tab.

And of course, you could write your own span snippet that does some  
more specialized behavior. The bundle already has a bunch of example  
snippets.
