How to go to brother node in xml file, i want to go step back to parent node and then go step forward to brother node

<Kms_Section>ffffff</Kms_section>  
<Kms_Description>bbbb</kms_description>

Answer 1

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.
}

Answer 2

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.
} 

Answer 3

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.
