    // if the nodes you want are identified by 'tag', use this:
    var nameNodeList = doc.GetElementsByTagName("name");

    // if you know the xpath to the specific node you want, use this:

    // if there are several nodes that have the same xpaths, use this:
    var selectNameList = doc.SelectNodes("the/xpath/that/may/match/many/nodes");

    // getting the value depends on the if you have an XmlNode, XmlElement or XmlNodeList
    // if you have a single XmlElement or XmlNode you can get the value one of these ways depending on the layout of your document:
    var name = nameElement.InnerText;
    name = nameElement.InnerXml;

    // if you have an XmlNodeList, you'll have to iterate through the nodes to find the one you want, like this:
    foreach (var node in nameNodeList)
    {
        // here use some condition that will determine if its the element/node you want or not (depends on your xml layout)
        if (node is XmlNode n)
