XPath Query

[Mark]

Hi,

I have a web service that returns some XML based on a query made by the
client. The order of this data is important and as such I use the following
code to achieve this:

XPathNavigator xpnNavigator;
xpnNavigator = xpdEventDocument.CreateNavigator();
xpnNavigator.MoveToRoot();

XPathExpression xpeEventExpression =
xpnNavigator.Compile("event_service/event");
xpeEventExpression.AddSort("@type", XmlSortOrder.Descending,
XmlCaseOrder.None, "", XmlDataType.Text);

XPathNodeIterator xpiEventIterator =
xpnNavigator.Select(xpeEventExpression);

The problem is that I have not found an easy way to return the data in XML
format. At the moment I have a few helper methods that loop through the
XPathNodeIterator and append the results to a string. Is there a better was
to do this?

Many thanx in advance,

Mark
