Hey Mark,

Right after you create those. OK, let's say I'm smack in your XML
parsing code. It probably goes something like this:
// general loop over some XML nodeset -- n is the current node
var div = document.createElement('DIV');
div.id = 'clipping_' + ....;
...
someParentNode.appendChild(div);
// end of loop
Am I right?
Now, what you can do is this, right after appendChild:
div._myDraggable = new Draggable(div, { ...options... });
That takes care of the creation time.
Now, the code that strips existing DIVs from their container before
creating new ones in their stead could go like this:
1) Fetch the DIVs. If these are the only children of your container,
go like this:
var divs = $('containerId').immediateDescendants();
If there are other things, but they have a specific class:
var divs = $('containerId').getElementsByClassName('clipping');
If they only have their ID pattern to identify them, go like this:
var divs = $('containerId').immediateDescendants().select(
function(div) { return div.id.startsWith('clipping_'); });
Now, you can deregister their draggables:
divs.each(function(div) { div._myDraggable.destroy(); });
And you can remove them (either on the fly, in the callback function:
divs.each(function(div) { div.remove()._myDraggable.destroy(); });
Or by clearing the container:
$('containerId').update('');
However, you might want to split deregistration and removal, since the
fetch-and-destroy-draggable bit can be used for toggling dragging off,
as well. And symetric code can be used for toggling it on (reusing the
create-and-assign line described earlier).
