Linq to Xml：删除命名空间

Question

I am retrieving an element or node from my xml doc. All goes well but when I retrieve the node it gets assigned the namespace of my root. This I don't want. I just want the node as it was before (without namespace).

My element that is retrieve is eg xElement. I am tried

1. xElement.Attributes("xmlns").Remove();
2. xElement.Attributes("xmlns").Where(x=>x.IsNamespaceDeclaration).Remove();

None of them did the trick.

I even tried this example: https://social.msdn.microsoft.com/Forums/en-US/9e6f77ad-9a7b-46c5-97ed-6ce9b5954e79/how-do-i-remove-a-namespace-from-an-xelement?forum=xmlandnetfx This left met with an element with an empty namespace xmlns=""

Please help.

As stated here

Based on interface:

 string RemoveAllNamespaces(string xmlDocument);

I represent here final clean and universal C# solution for removing XML namespaces:

 //Implemented based on interface, not part of algorithm 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))); }

Above solution still have two flase

• It ignores attributes
• It doesn't work with "mixed mode" elements

Here is another solution:

 public static XElement RemoveAllNamespaces(XElement e)
 {
    return new XElement(e.Name.LocalName,
      (from n in e.Nodes()
        select ((n is XElement) ? RemoveAllNamespaces(n as XElement) : n)),
          (e.HasAttributes) ? 
            (from a in e.Attributes() 
               where (!a.IsNamespaceDeclaration)  
               select new XAttribute(a.Name.LocalName, a.Value)) : null);
  }
