[thelist] Document loading & status bar

Below i have part of my xml document:

<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
<names>
	<name id="1" firstname="peter" last="john"/>
	<name id="2" firstname="anthony" last="peter"/>
	<name id="3" firstname="stevenson" last="ngila"/>

<names>
<><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>

What i want to achieve is, everytime this document is been loaded, my status
bar shows "Page Loading..."
and when it finishes loading the status bar shows "Done.".

Using Javascript, how can i achieve this?
