No, the xml file is just how/where they are placed and will look like.
Its place is in.. guess it was: /home/$USER/.config/openbox
To start your apps, its the common folder (might need to create it first, though) /home/$USER/.config/autostart
Just place some basic *.desktop files in there, they MAY include special startup arguments.
I've used them to have a backround terminal without decoration, maximized but not fullscreen, so i can still 'access' my hidden menubar
Here's what i've added to lxde-rc.xml:
(note the diffrences between lxterminal and sea console)
PHP Code:
<!-- # my stuff
sudo leafpad $HOME/.config/openbox/lxde-rc.xml
obxprop | grep "^_OB_APP" # this one's to get the apps info: role, name, type, etc
-->
<!-- Terminal -->
