创建System.Xml.XmlDocument，而不是从字符串创建

Question

It is possible to create a System.Xml.XmlDocument without initializing by parsing a string?
I want to create a XmlDocument representing the XML <rootEl />

I known the normal way to initialize an XmlDocument is by string-parsing as below:

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.LoadXml("<rootEl />");

However, is it possible to use the method outlined below?

System.Xml.XmlDocument doc = new System.Xml.XmlDocument("rootEl");    

(I understand System.Xml.Linq seems to be more flexible, but right now I am stuck with oldschool.)

Answer 1

Well, it's not possible to do it with exactly the code you've given. There's no constructor for XmlDocument which takes the content, either as a stream or as a string.

On the other hand, you could write:

XmlDocument doc = new XmlDocument();
doc.AppendChild(doc.CreateElement("rootEl"));

Is that what you want? Please be more specific about what you're trying to achieve.

Answer 2

I think you can't do it the way you want.

Not sure if this is what you need, but you could do it like this:

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
FileStream fs = new FileStream("whatever.xml", FileMode.Create);

XmlWriter writer = XmlWriter.Create(fs);


writer.WriteRaw("<rootEl>");
writer.WriteRaw("<rootEl />");

writer.Flush();
fs.Close();
