I have slogged through saving my data to an XML it wasn't very easy to
learn about it but once I figured it out it is very easy to read and
navigate the file. there was no help in the VBA system so you have to
go to the MS site to find it and it is not geared for VBA so it was a
bit of work to figure it out. What helped me is to find the XML notepad
program which I set up a dummy file to help me figure out how I wanted
to format my data and then try and program it. here is a small snip it
of my code. it is used to save and retrieve my UDT which is used in
multiple drawings.
