bash Arrays to fill in xml file, array inside an array?

I have an xml file I am trying to create with a bash script and it is not too difficult with the echo command. However I need to grab all of the files in a directory which are a cad type and bring it in to the xml. I do this with an array getting the entire directory path as it is needed for the first part of the xml. This is where it gets difficult because I need to strip off the path and extension and place this into the xml 3 or 4 times for each item in the folder. I have tried an array inside an array but this just makes more lines then needed.

Here is a sample of what it needs to look like. this is for 1 file in the folder and there could be 20 or more and I will not know at anytime how many. My script has changed many times but here is a version that is close. see below sample.
