Don't panik! And first of all: you don't bother anybody here in this forum. Welcome!
I cannot give you really a solution, because I don't have your skin, but I give you some clues to unravel your thinking about the <include/>-statement.
* Why there are so many XML-files?
In reality of the WA3 skinparser there exist just one XML-file named "skin.xml", inside the root-folder of your skin. That means if you include all files, which are excluded by the "Default"-skinmakers, you will get one big XML-file. Look at or download Default.xml
. And that should be your basis if you think about the pathes (folder hierarchy on your hard disk) of your images and XML-files.
* If so, why is there that <include/>-tag?
It gives you the ability to take over parts of another skin in your skin, without to load the whole other "skin.xml" and also its bitmaps you don't want to have. Also you can group (excluded) parts of your skin.xml with the proper PNG-images in a folderstructure you want. Extremes are to put all the stuff you have in one folder on your hard disk or make for every datafile an unique one.
* Aha! There are 2 path structures. One for the include-tags and one for the folders, where you put your images in.
Yes, approximately. Computer scientists would scream out but they are no beginners. That's a good model for understanding.
* Including the "Default"-Playlist-part in my skin ?
If your XML-file strcture is still like those of the "Default"-skin and you have still the "skin-pieces.xml" exchange folowing line:
<include file="pledit.xml"/> with
<include file="../default/xml/pledit.xml"/> .
That means starting from your skin-root-folder: "back","/go_into_default-folder", "/then_go_in_xml-folder", "/reference_default_pledit.xml".
Another way is to just delete that line from your "skin-pieces.xml" - your skin will automatically load the default one.
Hopefully this will help you.
P.S.: Hello to the native english speaking people. When do I write words together e.g. : rootfolder or root folder or root-folder? I have problems with it
