How do you remove Namespaces in XMLs

[bekets]

Hi All,

I need to remove all namespaces from xml file shown after c sharp code (also been attached).
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 'http://sample.response.power.core.com' within the same start element tag.
at System.Xml.XmlWellFormedWriter.PushNamespaceExplic it(String prefix, String ns)
at System.Xml.XmlWellFormedWriter.WriteEndAttribute()
at System.Xml.Linq.ElementWriter.WriteStartElement(XE lement e)
at System.Xml.Linq.ElementWriter.WriteElement(XElemen t 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 think of an alternative way of removing namespaces within an xml file or figure out the issue with my code please?

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.IO;
using System.Xml.Serialization;
 
namespace ConsoleApplication2
{
    class Program
    {
        public static string RemoveAllNamespaces(string xmlDocument)
{
XElement xmlDocumentWithoutNs = RemoveAllNamespaces(XElement.Parse(xmlDocument));
return xmlDocumentWithoutNs.ToString();
}
//Core recursion function
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())
xElement.Add(attribute);
return xElement;
}
return new XElement(xmlDocument.Name.LocalName, xmlDocument.Elements().Select(el => RemoveAllNamespaces(el)));
}
 
 
 
        static void Main(string[] args)
        {
            XmlDocument document = new XmlDocument();
            document.Load("C:\\temp\\xmlfile.xml");
 
            XmlNamespaceManager mgr = new XmlNamespaceManager(document.NameTable);
            mgr.AddNamespace("ns", "http://sample.stock.power.vno.com");
            XmlNodeList nodes = document.SelectNodes("/GetOrderMessagesResponse/ns:orderResponses/ns:OrderResponse", mgr);
            foreach (XmlNode n in nodes)
            {
 
                XmlDocument outdoc = new XmlDocument();
                XmlNode targetNode = outdoc.CreateElement("OrderResponse");
                targetNode = outdoc.ImportNode(n, true);
                targetNode.Attributes.RemoveAll();
                outdoc.ImportNode(targetNode, true);
                outdoc.AppendChild(targetNode);
 
                XmlSerializer serializer = new XmlSerializer(outdoc.GetType());
                XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
                ns.Add("","");
                StringWriter myWriter = new StringWriter();
                serializer.Serialize(myWriter, outdoc, ns);
 
                String temp = myWriter.ToString();
                Console.WriteLine(RemoveAllNamespaces(temp));              
 
 
                Console.ReadKey();
            }

Hi Zmbd,

You can use the following function to remove all namespaces

static XElement stripNS(XElement root)
{
return new XElement(
root.Name.LocalName,
root.HasElements ?
root.Elements().Select(el => stripNS(el)) :
(object)root.Value
);
}
