How can I write an XmlElement to an XmlTextWriter, where the element may have children

Question

Hi all;

Is there an easy (single call) way in .NET to write an XmlElement to a XmlTextWriter where that element is written out in full to the output?

Where the XmlElement may have many child elements and they have children, etc. And where it explicitly adds namespaces as needed.

thanks - dave

XmlElement and XmlDocument both inherit XmlNode, and both of them have WriteTo() method. You should be able to call XmlElement.WriteTo(XmlWriter) Method to solve your problem.
In addition, you don't need to care whether it has children, c# will handle it correctly.
A simple code example for my test:

        static void Main(string[] args)  
        {  
            XmlDocument doc = new XmlDocument();  
            doc.PreserveWhitespace = true;  
            doc.Load(@"D:\test\xml\booksData.xml");  
  
            XmlElement root = doc.DocumentElement;  
            
            XmlElement elem = doc.CreateElement("price");  
            elem.InnerText = "19.95";  
            root.AppendChild(elem);  
              
            using (XmlTextWriter w = new XmlTextWriter(@"d:\test\xml\out.xml", Encoding.UTF8))  
            {  
                root.WriteTo(w);  
            }  
        }
