XDocument remove namespace

Question

Hi,

does anybody know how to remove the namespace of a XML loaded into XDocument object? I already tried removing all attributes or the xmlns attribute only but looks like it's read-only.

Thanks,

Tom

Hi Tom,

 

As I understand, you can't remove namespace for XmlDocument in-memory. Namespace is integral part of name, so you have to recreate any element, which is in the namespace. Alternatively strip namespaces while writing XmlDocument out using some custom XmlWriter, try to look into this blog for details - http://blogs.msdn.com/kaevans/archive/2004/08/02/206432.aspx

Besides, you can try to remove XML namespace using regular expression as the following sample codes and see if it works on your side:

Code Block

XmlDocument stripDocumentNamespace(XmlDocument oldDom)
{
// Remove all xmlns:* instances from the passed XmlDocument
// to simplify our xpath expressions.
XmlDocument newDom = new XmlDocument();
newDom.LoadXml(System.Text.RegularExpressions.Regex.Replace(
oldDom.OuterXml, @"(xmlns:?[^=]*=[""][^""]*[""])", "",
System.Text.RegularExpressions.RegexOptions.IgnoreCase | System.Text.RegularExpressions.RegexOptions.Multiline)
);
return newDom;
}

 

This one gets rid of all "xmlns:{alias}" occurencies in the document, but you can limit it by making the Regex more restrictive if needed. Try to check out this blog for more details - http://www.pluralsight.com/blogs/keith/archive/2005/10/19/15714.aspx

 

hope this helps,

Regards,

If you'd like to process an XML document as if the "Namespaces in XML 1.0" specification doesn't have any impact on the data model, you can apply an in-place transformation on the document that not only removes all the namespace declarations but also moves all element and attribute names into XNamespace.None. I'm not sure why you would like that but it's certainly possible with LINQ to XML:

 

Code Block

static void Main() {
    XElement root = XElement.Parse(@"
<root xmlns='default namespace'>
    <e p:a='value' xmlns:p='p namespace' b='value'/>
    <q:f xmlns:q='q namespace'/>
</root>
");
    foreach (XElement e in root.DescendantsAndSelf()) {
        if (e.Name.Namespace != XNamespace.None) {
            e.Name = XNamespace.None.GetName(e.Name.LocalName);
        }
        if (e.Attributes().Where(a => a.IsNamespaceDeclaration || a.Name.Namespace != XNamespace.None).Any()) {
            e.ReplaceAttributes(e.Attributes().Select(a => a.IsNamespaceDeclaration ? null : a.Name.Namespace != XNamespace.None ? new XAttribute(XNamespace.None.GetName(a.Name.LocalName), a.Value) : a));
        }
    }
    Console.WriteLine(root);
    Console.WriteLine(root.Element("e").Attribute("a"));
}

Hi friend,

 

I was facing the same issue and i was able to fix it.

 

It is as simple as that.

 

The parent Node would obiviously have an xmlns argument as it was created. May if the parent node does not have it just check the immediate parent. Just give the xmlns argument given to the parent elements as you start creating new nodes under the parent element. It would create the node without the xmlns argument.

Hi friends,

 

I have generated an xml and cannocialised it. Then a portion of the xml is extracted to generate a security code that acts as the input value of a tag in the same xml that is inserted subsequently in the same xml.

 

But by means of validation it has been identified that the value computed is wrong.

 

So can anyone please help me with the code that cannocialises a part of the xml and generates the encrypted value of the body of the xml using the SHA1 algorithm.

 

I have tried the whole thing using the references given here but it has been identified as generating an incorrect value.

 

Regards

Harikrishnan

XDocument doc = XDocument.Load(filePath, LoadOptions.PreserveWhitespace);

doc.Descendants().Attributes().Where(a => a.IsNamespaceDeclaration).Remove();

doc.Save(filePath, SaveOptions.DisableFormatting);

Answer 6

doc.Descendants().Attributes().Where(a => a.IsNamespaceDeclaration).Remove();

Perfect! Just what I was looking for!

Answer 7

It doesn't work when I use the code:

XDocument doc = XDocument.Load(filePath, LoadOptions.PreserveWhitespace);

doc.Descendants().Attributes().Where(a => a.IsNamespaceDeclaration).Remove();

doc.Save(filePath, SaveOptions.DisableFormatting);

my output xml code still remain a mark of namespace "xmlns".

is there any other parameters should notice? Help me!

Answer 8

XElement doc = XElement.Parse(ToXml());
doc.DescendantsAndSelf().Attributes().Where(a => a.IsNamespaceDeclaration).Remove();
var ele = doc.DescendantsAndSelf();
foreach (var el in ele)
    el.Name = el.Name.LocalName;

Works for me!

Answer 9

XElement doc = XElement.Parse(ToXml());
doc.DescendantsAndSelf().Attributes().Where(a => a.IsNamespaceDeclaration).Remove();
var ele = doc.DescendantsAndSelf();
foreach (var el in ele)
    el.Name = el.Name.LocalName;

Works for me!

This works for me too! Thank you!
