I like this feature, sweety!

First thanks a lot to my colleague, Eunge. He helped me to solve this problem. And it’s really a long time I haven’t written .Net codes.

Sometimes we need to get InnerXML from the XPathNodeIterator, especially when you are writing codes in XSLT.

If you are using .Net Framework 2.0, it’s very easy. There is a property, InnerXML, in XPathNavigator, and from disassembled code we could find new functionalities of XMLWriter. But if you are using .Net 1.1, it’s really not quite convenient to do it. And there are two concrete classes which inherit abstract class XPathNavigator. One is XPathDocumentNavigator, the other is DocumentXPathNavigator. There is an important difference between two classes. DocumentXPathNavigator implements the interface IHasXmlNode, but XPathDocumentNavigator not. That means if your XPathNavigator is DocumentXPathNavigator, it’s easy to get InnerXML.

[code=csharp]
XPathNavigator nav = dom.CreateNavigator();
// do some select
String innerXml = ((IHasXmlNode)nav).GetNode().InnerXML;
[/code]
