Sort XML with C# Before Write

Question

I have an xml document that I am creating using the loop below and the XML writer from C#. It currently works fine, but I wanted to implement a solution where every time the XML is written it automatically sorts it ascending using the driveStart field. I know people say you should do this in XSLT but I am having a hard time finding a good example to follow. Anyone have any experience in this that I can use? Any help is greatly appreciative.

XmlDocument doc = new XmlDocument();
XmlElement rn = doc.CreateElement("DriveLayout");
XmlElement dn = null;
XmlAttribute xa, xa1, xa2, xa3, xa4, xa5, xa6;
doc.AppendChild(rn);

foreach (GridItem item in this.fileSystemGrid.Items)
{
  dn = doc.CreateElement("Drive");
  xa = doc.CreateAttribute("driveTime");
  xa.Value = item["DriveTime"].ToString();
  xa1 = doc.CreateAttribute("driveStart");
  xa1.Value = item["DriveStart"].ToString();
  xa2 = doc.CreateAttribute("driveEnd");
  xa2.Value = item["DriveEnd"].ToString();
}

dn.SetAttributeNode(xa);
dn.SetAttributeNode(xa1);
dn.SetAttributeNode(xa2);
rn.AppendChild(dn);

return doc.InnerXml;

Answer 1

Why do you want to sort it? How will it be used? Normally, XML is just data, and isn't sorted just to make it look pretty.

Answer 2

Sort your collection by their DriveStart before using the xml writer.
