From the sample xml, I am trying to select a book and then select the
author of the select book.
In the example code first SelectSingleNode selects a book. Second
SelectSingleNode on the book node should return the author of the
selected book (???). But I am getting the first author in the document
(Margaret Atwood), not the author of the selected book (Jane Austen).
Thanks.
Sample Code:
-----------------------------------------------
using System;
using System.IO;
using System.Xml;
public class Sample
{
public static void Main()
{
XmlDocument doc = new XmlDocument();
doc.Load("booksort.xml");
//Create an XmlNamespaceManager for resolving namespaces.
XmlNamespaceManager nsmgr = new
XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("bk", "urn:samples");
//Select the book node with the matching attribute value.
XmlNode book, author;
XmlElement root = doc.DocumentElement;
book =
root.SelectSingleNode("/descendant::book[@bk:ISBN='1-861001-57-6']",
nsmgr);
Console.WriteLine(book.OuterXml);
author = book.SelectSingleNode("/descendant::author");
Console.WriteLine(author.OuterXml);
}
