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:\Temp\books.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:\Temp\books.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:\Temp\books.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.
