<HL>Italy's Commercial Vehicle Sales</HL>

and this below code is not working why ?

       System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
    doc.Load("docs.xml");

    XmlNodeList elemList = doc.GetElementsByTagName("DOC");
    for (int i = 0; i < elemList.Count; i++)
    {
        string docno = elemList[i].Attributes["DOCNO"].ToString();
    }

Using Linq To Xml to parse Xml is much more easier. For example,

var xDoc = XDocument.Load("docs.xml");

var docs = xDoc.Descendants("DOC")
            .Select(x => new{
                DocNo = x.Element("DOCNO").Value,
                Text = x.Element("TEXT").Value
            })
            .ToList();
