Select Top XML Nodes using XPath in C#

Wed, Dec 2, 2009

Following exampel demonstrates how can we select Top N nodes from an XML document.
We can use method XmlNode.SelectNodes and Pass XPath expression as a parameter to select Xml Node.

Sample XML file

<Names>
    <Name>James</Name>
    <Name>Wyane</Name>
    <Name>Green</Name>
    <Name>Ballack</Name>
    <Name>Gallass</Name>
    <Name>Rahul</Name>
    <Name>Cashmen</Name>
</Names>

We can get all nodes by using this XPath expression:

 /Names/Name.

We can get only top 5 nodes by using XPath expression:

 /Names/Name[position() <= 5]

Sample Code

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
XmlNodeList nodes = doc.SelectNodes("/Names/Name[position() <= 5]");
foreach (XmlNode node in nodes)
{
  Console.WriteLine(node.InnerText);
}

OUTPUT:

Frank
Wyane
Green
Ballack
Gallass
