Oh well, at least you made the structure simple.:)

Okay; Probably can just make a new file based on the default.

Matthew, Joe do you know what he is talking about? All, AFAIK,  that is

needed, at this point, is to take output.xml tags & content and put
them in 
the correct spots with the correct xfce4rc tag names.  It is more of a
job and then a transform to the new tag name with content.
Then, some contents of tags need to be changed and some conditionals
added to complete the task.
-can y'all do that easily with Perl-XML-XSLT  or perl-XML-LibXSLT 
or is that a monster task?

The exact number cannot be calculated before the user xfce3rc file is
parsed but whatever is in [Popups] gets  ~ 7 added to it for the clock,
separators, etc.
That [Popups] number is in the Output.xml file as:

The y position should be done to determine if it is Top or Bottom; 
the x coordinate could be an interpolated value.  However, maybe 
just setting x to 0 would be ok, too. Certainly easier.  I like easy.

I have that coded into the XML tag:
       means tag for <Control  id blah> 
                            <Command>    </Command>
       means tag goes into the first Group( relative to the additional
default groups)
    <Command-Group12>xcalc -geometry -0+52</Command-Group12>
       means tag goes into the twelfth Group which is relative to the
additional default groups of Xfce Clock, separator, etc.  so it would
actually be the  ~ 20th 'Group' position in the xfce4rc file if clock,
mailcheck, a few separators and the switcher or pager are included as
they s/b.

And, BTW, it could be automated at all. The txt2XML "rules" do not have
the constructs for looping and incrementing, etc.

Those are coded in the OUTPUT.xml also as 
but tooltip will either be  empty or just have the command(as in
I lean toward empty since it is easier but having the tooltip as the
command, initially, would make it more XFce3-like.

Just as you have it in the default file.  Except, for consistency,
clock would be on the left(at the top of the Groups) and 
libsystembuttons.so  would be on both sides
 of the pager/switcher with separators.

Yes.  I did and that's what I surmised. Will look again, too.(and
again, and agin...:).

Yes. Thank you. I appreciate you taking the time to explain. It helps
to verify what I guesstimated was true and gave me some good advice on
some pitfalls to avoid.  That's a really good thing.

Currently, the txt2XML perl program from NASA ADC* and my rules.xml
file will produce XML from the ~/.xfce/xfce3rc file(non-destructively)
which can be transformed into a different XML format or even another
Markup Language.  That's supposed to be XSL's thing and it should be
quite straight forward.  I hope so ...

I have tested the "rules" with as many different well-formed xfce3rc
files that I can here.  I have been using 3.16 for quite a while but
built 3.18 and will test it with it too, soon(I do not know if there is
any difference -i hope not!).  Of course, anybody is welcome to the
xfce324_rules.xml file for testing/usage(it's only ~75kB).
