Question

My xml file:

<?xml version="1.0" encoding="utf-8"?>
<layout name="layout">
  <section name="Header">
    <placeholder name="headers" width="30" class="header">sam,pam</placeholder>
  </section>
  <section name="Content">
    <placeholder name="RightA" width="55">location</placeholder>
  </section>
</layout>

I want to replace whole node if its contain sam.Means if node contains sam I want to rewrite node:

<placeholder name="headers" width="4,5,91">sam,sam2,pam</placeholder>

instead of:

<placeholder name="headers" width="30" class="header">sam,pam</placeholder>

In c#:

XmlDocument doc = new XmlDocument();
string sFileName = @"FileNameWithPath";
doc.Load(sFileName );
foreach (XmlNode ....... )
{
    //Need help hear how to loop and replace.
}

Thanks.

XmlDocument xmlDoc = new XmlDocument();
 xmlDoc.Load("Path");
 XmlNodeList nodeList = xmlDoc.SelectNodes("section") ;

 foreach (XmlNode node in nodeList)
   {
      XmlNode childNode = node.SelectSingleNode("placeholder");
        if (childNode.Value.Contains("sam"))
          {
              childNode.Value = "sam,pam,sam2";
              childNode.Attributes["width"].Value = "4,5,91";

           }
   }

 xmlDoc.Save("Path");
