Well, the xml code shown in ric's example is definitely not xfce4rc
style. As a side note, there is no dtd, nor a xslt script, it's just
tags invented by me to obtain a structured tree for the config data that
can be parsed and writen by libxml. Oh, and don't merge with anything,
just create a new file. That will save you a lot of problems ;)

If you have all information I would consider writing it from the perl
data structure directly to xfce4rc style xml.

The information you need is

general: number of items (this important! includes clock and
pager/switcher), size, I would not do position, since it will be wrong
anyway (panel will have different size)

for each item:
type of item
item data : different for each type <-- this is probably difficult to
automate. You have to make a special case function for each type.
with submenu : yes or no
submenu data: launcher items

The launcher type is most common. It needs icon, command, caption (only
for menu items) and optionally tooltip.

Others are clock, mailcheck, pager or desktop switcher. They are defined
by their library name (e.g. <Control id="-1" filename="libclock.so"/>)

General format:
<?xml version="1.0"?>
<Xfce>
  <Panel/>
  <Groups>
    <Group>
      <Popup>
        <Item></Item>
        ...
      </Popup>
      <Control></Control>
    </Group>
    ...
  </Groups>
</Xfce>

Look at the default config file for more specific examples.

Hope this helps,
