(Sorry about the late answer, I was quite busy these last few months ...)

The XmlNode.TextContent property is actually what you're looking for : it  
defines the node's text content without these entities. For example, this  
little code :

   Dim doc As New XmlDocument

   doc.FromString("<xml>Fish & chips</xml>") 'This can be doc.Open(),  
doc.Content = "..." or whatever

   Print doc.ToString()

   Print doc.Root.TextContent

... will output this :

   <?xml version="1.0" encoding="UTF-8"?><xml>Fish & chips</xml>
   Fish & chips

Moreover, you have the static couple of methods XmlNode.Serialize() and  
XmlNode.Deserialize() that allow you to convert strings back and forth  
between the "with entities" and "without entities" representations.
