C# code

    public static bool IsSelectNode(string xmlPath, string node)
    {
        using (XmlReader reader = XmlReader.Create(xmlPath))
        {
            while (reader.Read())
            {
                if (reader.Name == node && reader.NodeType == XmlNodeType.Element)
                    return true;
            }
        }
        return false;
    }
