Scenario: Need to produce a new xml document with particular node list sorted in ascending/descending order

Code:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"Input.xml");

XmlDocument xmlDocCopy = new XmlDocument();
xmlDocCopy.LoadXml(xmlDoc.OuterXml);
xmlDocCopy.SelectSingleNode("//Links").RemoveAll();

XmlNode node = xmlDoc.SelectSingleNode("//Links");
XPathNavigator navigator = node.CreateNavigator();
XPathExpression selectExpression = navigator.Compile("Link/Title");
selectExpression.AddSort(".", XmlSortOrder.Ascending, XmlCaseOrder.None, "", XmlDataType.Text);
XPathNodeIterator nodeIterator = navigator.Select(selectExpression);
while (nodeIterator.MoveNext())
{
    XmlNode linkNode = xmlDoc.SelectSingleNode("//Link[Title=\"" + nodeIterator.Current.Value + "\"]");
    XmlNode importedLinkNode = xmlDocCopy.ImportNode(linkNode, true);
    xmlDocCopy.SelectSingleNode("//Links").AppendChild(importedLinkNode);
}

xmlDocCopy.Save(@"Output.xml");

Input:

<Section>
    <Links>
        <Link Id="1">
            <Title>Jupiter Line</Title>
            <AddedDate>27/05/2007</AddedDate>

Yeah, its official now. I have received the 2007 Microsoft MVP award for BizTalk Server. It's been a really fun year blogging, writing white paper, launching BizTalk 24 * 7 and just generally getting more involved in the community.

I feel proud and honored to be part of the select few that Microsoft recognizes as community leaders. I'll take this opportunity to thank each and everyone who nominated me for this award behind the scene.

 Nandri!
