从C＃中的xml文件获取元素

Question

I have an xml file which contains an element . i am storing the content of that xml file as string in csv in one of my projects.i am reading the content of that xml from csv and i want the data of the tag which exists in the content of xml file I tried like this.

XmlDocument doc = new XmlDocument();
doc.LoadXml(Convert.ToString(dataRow["XML"]));
var temp = doc.GetElementsByTagName("Mail");

but I am not getting the value of Mail into temp.what should i do?

Answer 1

GetElementsByTagName returns XmlNodeList . MSDN Reference

// Display all the book titles.
XmlNodeList elemList = doc.GetElementsByTagName("title");

for (int i=0; i < elemList.Count; i++)
{   
    Console.WriteLine(elemList[i].InnerXml);
}  

Linq solution:

var xDoc = XDocument.Load(dataRow["XML"].ToString());

var mailList = xDoc.Descendants("Mail")
                   .Select(x => new
                    {
                        MailID = x.Element("MailID").Value
                    })
                    .ToList();

UPDATE :

XmlDocument doc = new XmlDocument();
doc.LoadXml(Convert.ToString(dataRow["XML"]));
var temp = doc.GetElementsByTagName("Mail");

// loop through all retrieved "Mail" elements 
foreach(XmlElement xElem in temp)
{
     string sMailText = xElem.InnerText;
}
