I'm fairly new to vb.net (self-taught and realizing how much I DON'T know). I need to create an XML output file (I'm quite ignorant in this area as well!). I used an XMLDataDocument and Xml.XmlTextWrit er, creating each element node since the agency I'm sending the file to is very specific about the format.

How do I specify an element/node/attribute (whatever) to output xsi:nil="true"?


Desired Output:...
