<Kms_Section>ffffff</Kms_section>

Any reason you need to use the "old" XML API? With LINQ to XML you can just use NextNode... — Jon Skeet

You could use this code to get to the next kms_section2:

XmlNode FoundNode = null;
while (node.NextSibling != null && FoundNode == null)
{
    node = node.NextSibling;
    if (node.Name == "kms_section2")
    {
         FoundNode = node;
    }
}
if (FoundNode != null)
{
    //Do whatever you want.
}

I think you can use my earlier example. Instead of doing

XmlNodeList nodes =  doc.DocumentElement.SelectNodes("/KMS_doc/KMS_section");

you do

XmlNode parent = doc.DocumentElement.SelectSingleNode("KMS_doc");

and then you go with

XmlNodeList nodes = parent.SelectNodes("KMS_section");

you process all elements inside of nodes and then you go with

nodes = parent.SelectNodes("KMS_dataSection");

and process those elements.

The XmlNode object has a property that is called NextSibling. It is the next node under the parent node for the specified node. But I think you just want the next node in the XmlNodeList. You can loop through them like this:

foreach (XmlNode node in nodes)
{
  //Do whatever you want.
}
