[jQuery] Getting a fragment of ajax html and writing to the page

[jQuery] Getting a fragment of ajax html and writing to the page


Hi, can anyone tell me how I can get part of a web page downloaded
with $.get()? I thought it would be easy but ohhh no :( Here's a
snippet:
$("a[@class=popme]").click(function()
{
    $.get($(this).attr("href"), function(popUpData)
    {
        var popupContent = $(????);
        $.modal(popupContent );
    });
    return false;
});
At '????', I basically want to find the contents of a div in popUpData
with an ID of foo as a string I can pass to a modal pop-up. The web
page fetched is HTML 4.01 Strict.
Thanks for any help,
Richard
