  • Using Xpath With Default XML Namespace in C#

    If you have a XML file without any prefix in the namespace:

    <bookstore xmlns="http://www.contoso.com/books"></bookstore>

    you have this workaround:

    XmlTextReader reader = new XmlTextReader(@"C:Tempooks.xml");
    // ignore the namespace as there is a single default namespace:
    reader.Namespaces = false;
    XPathDocument document = new XPathDocument(reader);
    XPathNavigator navigator = document.CreateNavigator();
    XPathNodeIterator nodes = navigator.Select("//book");

    If you have a XML file with a prefix in the namespace:

    <bookstore xmlns:ns="http://www.contoso.com/books"></bookstore>

    Use this:

    XmlTextReader reader = new XmlTextReader(@"C:Tempooks.xml");
    XPathDocument document = new XPathDocument(reader);
    XPathNavigator navigator = document.CreateNavigator();
    XPathNodeIterator nodes = navigator.Select("//book");

    Of course, you can use a namespace manage if needed:

    XmlTextReader reader = new XmlTextReader(@"C:Tempooks.xml");
    XPathDocument document = new XPathDocument(reader);
    XPathNavigator navigator = document.CreateNavigator();
    XmlNamespaceManager nsmgr = new XmlNamespaceManager(reader.NameTable);
    nsmgr.AddNamespace("ns", "http://www.contoso.com/book");
    XPathNodeIterator nodes = navigator.Select("//book", nsmgr);

    I think that it's the easiest way to make the code working in the most cases.
