Question

We were given a sample document, and need to be able to reproduce the structure of the document exactly for a vendor. However, I’m a little lost with how C# handles namespaces. Here’s a sample of the document:

<?xml version='1.0' encoding='UTF-8'?> <Doc1 xmlns='http://www.sample.com/file' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'    xsi:schemaLocation='http://www.sample.com/file/long/path.xsd'>     <header>         <stuff>data</stuff>         <morestuff>data</morestuff>     </header>  </Doc1> 

How I’d usually go about this is to load a blank document, and then start populating it:

XmlDocument doc = new XmlDocument(); doc.LoadXml('<Doc1></Doc1>'); // Add nodes here with insert, etc... 

Once I get the document started, how do I get the namespace and schema into the Doc1 element? If I start with the namespace and schema in the Doc1 element by including them in the LoadXml(), then all of the child elements have the namespace on them — and that’s a no-no. The document is rejected.

So in other words, I have to produce it EXACTLY as shown. (And I’d rather not just write text-to-a-file in C# and hope it’s valid XML).

You should try it that way

  XmlDocument doc = new XmlDocument();      XmlSchema schema = new XmlSchema();   schema.Namespaces.Add('xmlns', 'http://www.sample.com/file');    doc.Schemas.Add(schema); 

Do not forget to include the following namespaces:

using System.Xml.Schema; using System.Xml;
