Concise XML Serialization


G

Guest

I am serializing a class to XML using the code below, but the XmlSerializer
opens the object's tag with some very verbose attributes: "<TestClass
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xml
ns:xsd="http://www.w3.org/2001/XMLSchema">"

I am serializing thousands of these objects, so for performance I would like
to exclude the "xmlns:" attributes. Is there an easy way to do that with the
standard XmlSerializer, or any other .NET serializers?

XmlTextWriter writer = new XmlTextWriter(Console.Out);
XmlSerializer serializer = new XmlSerializer(typeof(TestClass));
TestClass test = new TestClass();
serializer.Serialize(writer, test);
writer.Close();

Dave,

If you are serializing these objects to the same stream, then I would
recommend having a container object which holds all the references, and then
serializing that. It ^should^ prevent the XSI and XSD namespaces from being
replicated.

However, if you are serializing these to different streams, then there
is nothing you can do, since it needs those namespaces for the document to
be valid (and for the serializer to interpret some values as well).

Hope this helps.

I have several "collection" serialization examples at my blog:

Hi Dave,

Thank you for your post.

I agree with Nicholas on this, you cannot remove those namespaces since
they're required for the serializer to work correctly.

You may found following MSDN documentation useful:
