Find a class in .html()

I have a method in jQuery which is receiving a 'this' reference, so that I can filter out all the html by using:

showSomeThing = function (e) {
    $("#div").html($(e).html());
}

1. I want to do some filtering on this e before passing that to the div, e.g. I want to find a class named 'someclass' and set it's display to 'none' so that the class will not show in div above.

I'm trying this:

$("#div").html($(e).find("someclass").hide().html();

but it doesn't work.

2. I also want to search some particular attributes in the html and their values (once I am able to do the above).

Any ideas?
