This looks suspect.  It looks like the first tr.ReadString will read the <Entry> node so the following ReadString will start with the next <Style> element.
Is the XML file well formed? If so, you may want to consider using the XmlDocument or XmlNodeReader class to traverse the file. They are much easier to work with than XmlTextReader.
