Looping through XML Document

Question

My Method:

if (File.Exists( @"C:\config.xml"))
   {
    System.Xml.XmlDocument xd = new System.Xml.XmlDocument();
    xd.Load( @"C:\config.xml");
    System.Xml.XmlElement root = xd.DocumentElement;
    System.Xml.XmlNodeList nl = root.SelectNodes("/config");
    foreach (System.Xml.XmlNode xnode in nl)
    {
        string name = xnode.Name;
        string value = xnode.InnerText;
        string nv = name + "|" + value;
        Send(nv);
        }

My Xml Doc

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<config>
<bla>D</bla>
<def>300</def>
<ttOUT>34000</ttOUT>
<num>3800</num>
<pw>help</pw>
<err>1</err>
....and so on
</config>

Now my method returns the first 2 and nothing else. What am i doing wrong...

Answer 1

use the System.Xml namespace to avoid long type qualifications ie...

    using System.Xml;

Then try something like this..

    XmlNodeList nl = xd.SelectNodes("config");
    XmlNode root = nl[0];

    foreach (XmlNode xnode in root.ChildNodes)
    {
        string name = xnode.Name;
        string value = xnode.InnerText;
        string nv = name + "|" + value;
        Send(nv);
    }

I believe there is something wrong with your method.

a) I don't think SelectNodes should take the /config argument, rather it should take config.

b) After selecting the first (and only - XML files in .Net must have one and only one root node) root node you need to iterate through the ChildNodes of the root.

Answer 2

root is the <config> tag, so I don't understand how root.SelectNodes("/config") should work at all. Use root.Childnodes instead.
