Introduction

This sample shows how to use the XPathNavigator to with CreateNavigator to iterate over an Xml-Document loaded with XPathDocument.

This is the sample-Xml-document Books.xml:

<?xml version="1.0" encoding="utf-8" ?>
<books>
  <book auhtor="Ernest Hemmingway">Fiesta</book>
  <book author="Unknown">The principles of software development</book>
</books>

And here is the snippet to navigate the Xml-nodes and attributes:

private static void NavigateBooks()
{
    XPathDocument docBooks = new XPathDocument("../../Books.xml");
    XPathNavigator navBooks = docBooks.CreateNavigator();
    XPathNodeIterator iterBooks = navBooks.Select("books/book");

    foreach (XPathNavigator nodeBook in iterBooks)
    {
        Console.WriteLine("Found book: {0}", nodeBook.Value);
        Console.WriteLine("Author: {0}", nodeBook.GetAttribute("author", String.Empty));
    }        
}
