Getting an XML Nodes by its Attribute Value in C#

We will use method XmlNode.SelectNodes to get list of nodes selected by the XPath expression. Suppose we have this XML file.

To get all name nodes,we will use XPath expression /Names/Name.
To get only male names or to select all nodes with specific XML attribute,we will use XPath expression /Names/Name[@type='M'].
Import System.Xml namespace at the top of code-behind page.

using System.Xml;

string str_xml_node = string.Empty;
str_xml_node = "<Names><Name type='M'>Vishal</Name><Name type='F'>Vaishali</Name><Name type='M'>Neeraj</Name><Name type='M'>Kumar</Name></Names>";
XmlDocument emp = new XmlDocument();
emp.LoadXml(str_xml_node);

//For getting Male values
XmlNodeList xn_list = emp.SelectNodes("/Names/Name[@type='M']");
foreach (XmlNode xn in xn_list)
{
    Response.Write(xn.InnerText + "<br/>");
}

//For getting Female values
xn_list = emp.SelectNodes("/Names/Name[@type='F']");
foreach (XmlNode xn in xn_list)
{
    Response.Write(xn.InnerText + "<br/>");
}

Output:-
Vishal
Neeraj
Kumar
Vaishali
