Question

I am querying an XMLDocument using SelectNodes(). However, I need the return of the query to be in a particular order based on an element contained inside the nodes being queried. I don’t see any way to do this with SelectNodes method. How can this be accomplished?

Here is my query:

XmlNodeList booksNodes = xmlDoc.DocumentElement.SelectNodes("//BOOKS");

I want to order this by publication date which is an element contained inside the <BOOKS> node.

Try LINQ against your collection of nodes like here:

IOrderedEnumerable<XmlNode> booksNodes = doc.DocumentElement.SelectNodes("//BOOKS")
    .Cast<XmlNode>()
    .OrderBy(node => node.Attributes["title"].Value);
