如何使用 c# 为所有类似节点提供一致的值

我正在尝试为其中的所有相似节点插入一些一致的值。示例 XML 如下所示：

 <DrWatson>

我想替换<foundinBuild>标签的值。另外，请注意，我不想保存编辑，而是在运行时使用编辑后的 xml 以进一步在我的代码中。请提出一些解决方法。

      var doc = new XmlDocument();
            doc.Load("Your XML Path");
            XmlElement root = doc.DocumentElement;
            XmlNodeList nodes = root.SelectNodes("Bugs/Bug");                
            foreach (XmlNode node in nodes)
            {                 
                    node["foundInBuild"].InnerText = "Your New Value";                   
            }
