Moving an XML node up or Down

Hi,

Can anyone tell me how to move a node up or down in an xml document? For
example:

<root>
<field name="1"/>
<field name="2"/>
<field name="3"/>
</root>

I would like to move the field node name="3" up one position.

TIA

Ben

You might want to do a search for

Xml to Xml Transformation

...

This takes one Xml, uses an Xsl, to make another Xml (as opposed to an
output html file).

That might be the hint you're looking for.

DOM manipulation with InsertBefore can do that e.g.

     XmlDocument xmlDocument = new XmlDocument();
     xmlDocument.PreserveWhitespace = false;
     xmlDocument.Load(@"file.xml");

     XmlNode fieldNode = xmlDocument.SelectSingleNode(
@"/root/field[@name = '3']");

     if (fieldNode != null) {
       fieldNode.ParentNode.InsertBefore(fieldNode,
fieldNode.PreviousSibling);
     }

     // save changes somewhere
     // in this example simply the console to show changes
     xmlDocument.Save(Console.Out);

Note that white space can be an issue when deciding what "up one
position" means.
