Yes. Windows XP can be upgraded from the RTM release or a service pack to any subsequent service pack. For example: Windows XP RTM ---> Windows XP Service Pack 3 Windows XP Service Pack 1 ---> Windows XP Service Pack 3 Windows XP RTM ---> Windows XP Service Pack 2 Service Pack 3 is the latest service pack for Windows XP; any planned updates should be to this service pack, and not an older one. As per above, you do not need to install any previous service packs before installing Service Pack 3.
