I just realized that in my output example it should be tocEntry not Entry (from what my code has). That is what I get for trying to hurry!

Well, the root element is named "toc" so the code for that (which I didn't include) looks like this:
XmlElement root = doc.CreateElement("toc");
doc.AppendChild(root);

I suppose that I might could use streamwriter, but the source file is 1000's of lines, and I think it might get confusing trying to figure out when to close the child tags and which one is a sibling of which, parent of which, etc. This is a very small sample of the input and output. To avoid confusion and keep the relationships straight I was trying to use XPath.
