Thanks. Does this code work? If so, it's worse than I thought it was. 
I had assumed InnerXML worked with well-formed XML. It apparently 
doesn't. For example,

channel.InnerXml  = channel.InnerXml + "\n<item>\n<title>" + diaryTitle +
      "</title>\n<link>" + diaryLink + "</link>\n<description>" + 
diaryDesc + "</description>\n";

Where's the end-tag for the item element? There's another case of 
this a little further on:

channel.InnerXml  = channel.InnerXml + "\n" +
       "<rss:item xmlns:rdf=\"http://www.w3.org/1999/02/22-rdf-syntax-ns#\" " +
       "xmlns:rss=\"http://purl.org/rss/1.0/\" rdf:about=\"" + 
diaryLink + "\" >\n" +
       "<rss:title>" + diaryTitle + "</rss:title>\n<rss:link>" + 
diaryLink + "</rss:link>\n" +
       "<rss:description>" + diaryDesc + "</rss:description>\n";

This time it's the rss:item end-tag that's gone missing, unless I've 
misunderstood C# handles double quote escaping in strings.

The underlying problem seems to be that this approach mixes up the 
view of XML as a tree of nodes and XML as a sequence of text. Either 
view makes sense. Both views are useful for processing (though only 
the text is normative). But using them both at the same time is 
ultimately confusing.
