[mvp-xml-help] XPathIteratorReader and ReadInnerXml method

[Martin H. <Mar...@gm...>]

Hi there,

I am trying to get somehow familiar with parts of the MVP XML library.

I am having some trouble to understand how XPathIteratorReader is 
supposed to work, if I use ReadInnerXml() on it I do not get the result 
I expect (XML of all nodes of the iterator) but only the XML of the 
first node.

Assume example XML is alike

<?xml version="1.0" encoding="UTF-8"?>
<gods>
   <god>Kibo</god>
   <!-- All for Kibology -->
   <god>Xibo</god>
</gods>

then with a normal XmlTextReader and ReadInnerXml() I can do e.g.

     XmlTextReader xmlReader = new XmlTextReader(args[0]);
     xmlReader.MoveToContent();
     Console.WriteLine("Current node type: {0}, current name: {1}", 
xmlReader.NodeType, xmlReader.Name);
     Console.WriteLine("ReadInnerXml():\r\n{0}", xmlReader.ReadInnerXml());
     xmlReader.Close();

and the output is

Current node type: Element, current name: gods
ReadInnerXml():

   <god>Kibo</god>
   <!-- All for Kibology -->
   <god>Xibo</god>

that is ReadInnerXml() in the example gives me the serialized XML of all 
child nodes of the root element gods.

Now I thought the following use of XPathNodeIterator would give the same 
result:

     XPathDocument xmlDocument = new XPathDocument(args[0]);
     XPathNavigator xPathNavigator = xmlDocument.CreateNavigator();
     XPathNodeIterator nodeIterator = xPathNavigator.Select(@"*/node()");

     XPathIteratorReader iteratorReader = new 
XPathIteratorReader(nodeIterator, "gods");
     iteratorReader.MoveToContent();
     Console.WriteLine("Current node type: {0}, current name: {1}", 
iteratorReader.NodeType, iteratorReader.Name);
     Console.WriteLine("ReadInnerXml():\r\n{0}", 
iteratorReader.ReadInnerXml());
     iteratorReader.Close();

Result for me with .NET 1.1 and MVP XML library 1.2 is however:

Current node type: Element, current name: gods
ReadInnerXml():
<god>Kibo</god>


Is that the intended result? If the XPathIteratorReader is positioned on 
the faked root element gods why does ReadInnerXml() not output the 
serialized XML of all child nodes of that root element but only the 
serialized XML of the first element child node?
