getting "null" value for xml

Question

in this xml

<Roots>
   <Root Name="cab">element_list</Root>
</Roots>

I want to get the value of attribute Name which is cab and element_list

I have this code

XmlDocument doc = new XmlDocument();
doc.LoadXml("<Root Name=\"cab\">element_list</Root>");
XmlElement root = doc.DocumentElement;
var values = doc.Descendants("Roots").Select(x => new { Name = (string)x.Attribute("Name"), List = (string)x }).ToList();

What I get when I run the debugger is

values>  Name = "null",  List = "element_list"

I am not understanding why I am getting a null value when I should be getting cab for the attribute Name

Your `"element_list"` does not have `.Descendants("Roots")`. — GSerg, Oct 19 '22 at 23:46

Introduce a `` so that it could be found by `.Descendants("Roots")`? Change `.Descendants("Roots")` to something else so that it would find what there actually is? — GSerg, Oct 20 '22 at 00:27
The XML string you're passing to `doc.LoadXml()` is not the same as the XML document at the beginning of the question. That's significant. — Lance U. Matthews, Oct 20 '22 at 00:32
*In this XML* contains the `` element, while you try to load XML with the XML string without `` element, so which is the **real** XML data should be? — Yong Shun, Oct 20 '22 at 00:32

XDocument is much easier to work with compared to XmlDocument. Perhaps consider switching to it?

    public static void ParseXml()
    {
        string str = "<Roots><Root Name=\"cab\">element_list</Root></Roots>";

        using TextReader textReader = new StringReader(str);
        XDocument doc = XDocument.Load(textReader);

        var val = doc.Element("Roots").Element("Root").Attribute("Name").Value;

    }
