jquery ajax parse response text

Ok this is really frusturating me because I've done this a hundred times before, and this time it isn't working. So I know I'm doing something wrong, I just can't figure it out.

I am using the jQuery .get routine to load html from another file. I don't want to use .load() because it always replaces the children of the element I'm loading content into.

Here is my .get request:

$(document).ready(function() {
    $.get('info.html', {}, function(html) {
        // debug code
        console.log($(html).find('ul').html());
        // end debug code
    });
});

The file 'info.html' is a standard xhtml file with a proper doctype, and the only thing in the body is a series of ul's that I need to access. For some reason, the find function is giving me a null value.

In firebug, the GET request is showing the proper RESPONSE text and when I run

console.log(html);

Instead of the current console.log line, I get the whole info.html as output, like I would expect.

Any ideas?
