Hi All,

I need to remove all namespaces from an xml file. I am using the functions

public static string RemoveAllNamespaces(string xmlDocument)
   XElement xmlDocumentWithoutNs = RemoveAllNamespaces(XElement.Parse(xmlDocument));
   return xmlDocumentWithoutNs.ToString();

private static XElement RemoveAllNamespaces(XElement xmlDocument)
   if (!xmlDocument.HasElements)
    XElement xElement = new XElement(xmlDocument.Name.LocalName);
    xElement.Value = xmlDocument.Value;
    foreach (XAttribute attribute in xmlDocument.Attributes())
    return xElement;
   return new XElement(xmlDocument.Name.LocalName, xmlDocument.Elements().Select(el => RemoveAllNamespaces(el)));

The problem is that I am getting the following error being returned by one of the functions

{System.Xml.XmlException: The prefix '' cannot be redefined from '' to '' within the same start element tag.
   at System.Xml.XmlWellFormedWriter.PushNamespaceExplicit(String prefix, String ns)
   at System.Xml.XmlWellFormedWriter.WriteEndAttribute()
   at System.Xml.Linq.ElementWriter.WriteStartElement(XElement e)
   at System.Xml.Linq.ElementWriter.WriteElement(XElement e)
   at System.Xml.Linq.XElement.WriteTo(XmlWriter writer)
   at System.Xml.Linq.XNode.GetXmlString(SaveOptions o)
   at System.Xml.Linq.XNode.ToString()

Can somebody thing of an alternative way of removing namespaces within an xml file?

Many thanks

static XElement stripNS(XElement root)
            return new XElement(
                root.HasElements ?
                    root.Elements().Select(el => stripNS(el)) :

will remove all namespaces. Thanks ProgramFox for the pointer
