Select XML Nodes by Attribute Value

Select XML Nodes by Attribute Value [C#]

This example shows how to select nodes from XML document by attribute value. Use method XmlNode.Selec­tNodes to get list of nodes selected by the XPath expression. Suppose we have this XML file.
[XML]
<Names>
    <Name type="M">John</Name>
    <Name type="F">Susan</Name>
    <Name type="M">David</Name>
</Names>

To get all name nodes use XPath expression /Names/Name. To get only male names (to select all nodes with specific XML attribute) use XPath expression /Names/Name[@type='M'].

[C#]
XmlDocument xml = new XmlDocument();
xml.LoadXml(str);  // suppose that str string contains "<Names>...</Names>"
XmlNodeList xnList = xml.SelectNodes("/Names/Name[@type='M']");
foreach (XmlNode xn in xnList)
{
  Console.WriteLine(xn.InnerText);
}

The output is:
John
David
