First, I'd like to thank the authors for providing me with the first truly helpful text on working directly with XML data files.

I got almost all the way through the exercises when I threw an exception in the Address List. I get the following error: "Add failed. Duplicate key value supplied."

Visual Studio is telling me that, in the Case XmlNodeType.Text section, addressData and elementName are being used before they have been assigned values. I thought those values were assigned in the preceding Case XmlNodeType.Element section.

I tried pasting in the downloaded project code to theses sections, in case my copying skills are lacking, but it didn't help. Can anyone clue me in on what I might be doing wrong or not seeing?

Thanks in advance for any assistance.

OK. I'm stupid. I kept typing in "Addresses" instead of "Address". That fixed, I no longer throw an exception.

However, I now have a different problem. Instead of getting 3 different items in the Address list (one for each of the 3 items in my XML document), i get the same item listed 3 times.

I'm more confused than ever.

Please help.
