Set Root Namespace Prefix in an XDocument

Question

I currently have:

XNamespace xmlns = "XSDName";<br>
XNamespace xsi = @"http://www.w3.org/2001/XMLSchema-instance";<br>
XNamespace schemaloc = @"XSDName XSDName.xsd";
XDocument xdoc = new XDocument(
    new XElement("BaseReport",
    new XAttribute(xsi + "schemaLocation", schemaloc),
    new XAttribute(XNamespace.Xmlns+"ns1", xmlns),
    new XAttribute(XNamespace.Xmlns + "xsi", xsi));

This gives me:

BaseReport xsi:schemaLocation="XSDName XSDName .xsd" xmlns:ns1="XSDName" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

How can I have BaseReport read ns1:BaseReport?

Answer 1

The below code will give you the output that you want. The key is adding the defined namespace before the name and letting .NET figure out the correct prefix.

XNamespace xmlns = "XSDName";
XNamespace xsi = @"http://www.w3.org/2001/XMLSchema-instance";
XNamespace schemaloc = @"XSDName XSDName.xsd";
XDocument xdoc = new XDocument(
    new XElement(xmlns + "BaseReport",
    new XAttribute(xsi + "schemaLocation", schemaloc),
    new XAttribute(XNamespace.Xmlns + "ns1", xmlns),
    new XAttribute(XNamespace.Xmlns + "xsi", xsi)));
