The code works but you're right that it shouldn't. This looks like a bug in our implementation where the closing tag seems to be automatically inserted if the new InnerXml text ends with a newline.

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.
