Before posting this question I have tried all other solution on stack, but with no success.
I am unable to remove empty xmlns attribute from XElement using C#, I have tried the following Codes.
XElement.Attributes().Where(a => a.IsNamespaceDeclaration).Remove();
Another one which postted here
foreach (var attr in objXMl.Descendants().Attributes())
{
var elem = attr.Parent;
attr.Remove();
elem.Add(new XAttribute(attr.Name.LocalName, attr.Value));
}
Image This is you xml file
<Root xmlns="http://my.namespace">
<Firstelement xmlns="">
<RestOfTheDocument />
</Firstelement>
</Root>
This is you expect
<Root xmlns="http://my.namespace">
<Firstelement>
<RestOfTheDocument />
</Firstelement>
</Root>
I think the code below is what you want. You need to put each element into the right namespace, and remove any xmlns='' attributes for the affected elements. The latter part is required as otherwise LINQ to XML basically tries to leave you with an element of
<!-- This would be invalid -->
<Firstelement xmlns="" xmlns="http://my.namespace">
Here's the code:
using System;
using System.Xml.Linq;
class Test
{
static void Main()
{
XDocument doc = XDocument.Load("test.xml");
foreach (var node in doc.Root.Descendants())
{
// If we have an empty namespace...
if (node.Name.NamespaceName == "")
{
// Remove the xmlns='' attribute. Note the use of
// Attributes rather than Attribute, in case the
// attribute doesn't exist (which it might not if we'd
// created the document "manually" instead of loading
// it from a file.)
node.Attributes("xmlns").Remove();
// Inherit the parent namespace instead
node.Name = node.Parent.Name.Namespace + node.Name.LocalName;
}
}
Console.WriteLine(doc); // Or doc.Save(...)
}
}
如果将父元素的命名空间添加到元素,则空命名空间标记将消失,因为它不是必需的,因为该元素位于同一命名空间中。
您是否尝试通过值获取 Xelement.Attribute 以在删除之前查看元素是否为“xmlns”。
Xelement.Attribute("xmlns").Value
here's a simpler way to do this. I believe it happens when you create separate xml segments and then join them to your document.
xDoc.Root.SaveDocument(savePath);
private static void SaveDocument(this XElement doc, string filePath)
{
foreach (var node in doc.Descendants())
{
if (node.Name.NamespaceName == "")
{
node.Name = ns + node.Name.LocalName;
}
}
using (var xw = XmlWriter.Create(filePath, new XmlWriterSettings
{
//OmitXmlDeclaration = true,
//Indent = true,
NamespaceHandling = NamespaceHandling.OmitDuplicates
}))
{
doc.Save(xw);
}
}
