[jQuery] simple selector problem :beginner();

[tlob]

I like to select every span, thats in "this"
$(this "span")

sorry, simple and stupid...


full function:
function liCounting (){
                        $("#staerke1 li,#staerke2 li").each(function(liCounter){
                                liCounter++; //set liCounter to 1, not 0
                                $(this "span").replaceWith("<span>"+ liCounter 
+". </span>");
                        })
                        };
