Finding a given element in nested iframes *recursively*

What's the best possible way to find a given "div.myClass" element in the current document, as well as any iframes it (and their nested iframes, too) might have?

Thanks

Provided that frame access is not restricted by the same origin policy:

function getElem(selector, $root, $collection) {
    if (!$root) $root = $(document);
    if (!$collection) $collection = $();
    // Select all elements matching the selector under the root
    $collection = $collection.add($root.find(selector));
    // Loop through all frames
    $root.find('iframe,frame').each(function() {
        // Recursively call the function, setting "$root" to the frame's document
        getElem(selector, $(this).contents(), $collection);
    });
    return $collection;
}
// Example:
var $allImageElements = getElem('img');
