Remove xmlns attribute from xml

In below Xml, I tried to delete the xmlns attribute but, its unable to populate under, xmlNode.Attributes still appear under OuterXml and final XmlDocument.

... 
<z:Datac knid="2" xmlns="http://services/api/"></z:Datac>
...
<z:Datac knid="3" xmlns="http://services/api/"></z:Datac>
....
<z:Datac knid="5" xmlns="http://services/api/"></z:Datac>
....

How to remove xmlns attribute for each z:Datac element?

foreach (var item in nodes)
{
    var xmlnsAttribute = (item.Attributes has "xmlns" attribute)

    if (xmlnsAttribute != null)
    {
        Remove xmlNode...  //not able to reach here as not able to find xmlns.
    }
}

I don't have xml.linq

I guess you'd want something like:

XmlDocument doc = new XmlDocument();
doc.Load("my.xml");
foreach(var node in doc.DocumentElement.ChildNodes)
{
    var el = node as XmlElement;
    if (el != null)
    {
        if (el.HasAttribute("xmlns"))
        {
            var ns = el.GetAttribute("xmlns");
            if (ns != null && ns != el.NamespaceURI)
            {
                el.RemoveAttribute("xmlns");
            }
        }
    }
}
doc.Save("new.xml");

Obviously you'd probably want to make it query, or issue an all-elements query, in complex scenarios.
