I started a project today that has a user interface like a treeview, only list style (built with
html in a webgadget) that needs to maintain an underlying database to control it, and zoomed
into xml as the format of choice.
I had a foggy notion about what xml is all about, but this helped a lot:
w3schools explains what xml is
Very simple and to the point and a great help if you dont know what the PB xml lib is all about.
