Create a HTML string that includes nested numbered lists with indentation using VB.net

I need code that will take the elements (1,2,3) and (a,b,c's) on the attached Word document and build a string that will produce the same results if put into a div. It cannot have any external references. I need the numbers to be produced by the HTML such as <ol type=""A"">" and not hard coded. I need the indentations also. I will take your code and break it into pieces that I can build from a JSON object and loop in vb.net
