How to change stylesheet tag in an xml in .NET

Is there a way for me to change the stylesheet tag in an xml. Is there a way to do that.... ex if I receive

<?xml version="1.0" encoding="us-ascii"?>
<?xml-stylesheet type="text/xsl" href="www.somecompany.com/stylesheet.xsl"?>
<MedicalRecord>
......
......
</MedicalRecord>

I want to make it

<?xml version="1.0" encoding="us-ascii"?>
<?xml-stylesheet type="text/xsl" href="mystylesheet.xsl"?>
<MedicalRecord>
......
......
</MedicalRecord>

Note the href tag value has changed.

At it's simplest based on a straight replace:

XmlDocument doc = new XmlDocument();
doc.Load("XMLFile1.xml");
XmlProcessingInstruction pi = 
    (XmlProcessingInstruction)
         doc.SelectSingleNode("/processing-instruction('xml-stylesheet')");

// Replace href with the one we want
Regex r = new Regex("href=[\"']?((?:.(?![\"']?\\s+(?:\\S+)=|[>\"']))+.)[\"']?", 
                              RegexOptions.IgnoreCase | RegexOptions.Singleline);       
pi.Data = r.Replace(pi.Data, "href=\"mystyle.xsl\"", 1, 0);
