Xml.DocumentSource Will Not Load With Physical Path

Problem
ASP.NET Xml control will not load with physical path when XML file is not part of website. The following error is thrown:

Server Error System.Web.HttpException: 'c:\MyFolder\MyFile.xml' is a physical path.

Property System.Web.UI.WebControls.Xml.DocumentSource may not be a physical path to the requested XML file. It must be a virtual path that is a relative or root relative URL.

Solution
Tested on .NET Framework version 1.1.

1) Instantiate an XmlDocument using physical path.
2) Assign XmlDocument to Xml control

Example using a physical path:

<asp:xml id="xmlControl" transformsource="style.xslt" runat="server"></asp:xml>

...

protected System.Web.UI.WebControls.Xml xmlControl;

System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
xmlDoc.Load("C:\MyFolder\MyFile.xml");

xmlControl.Document = xmlDoc;

Example using a website path:

<asp:xml id="xmlControl" transformsource="style.xslt" runat="server"></asp:xml>

...

protected System.Web.UI.WebControls.Xml xmlControl;

xmlControl.DocumentSource = "/MyWebSiteFolder/MyXml.xml";
