XMLTextWrite类的一点简单的代码，

 

string fileName = @"d:\open.xml";

XmlTextWriter xmlw = new XmlTextWriter(fileName,System.Text.Encoding.Default);

xmlw.Formatting = Formatting.Indented;

 

xmlw.WriteStartDocument(true);

xmlw.WriteDocType("MyDef",null,null,"<!ENTITY I 'Italy'><!ENTITY I-Capital  'Rome'>");

 

                            xmlw.WriteStartElement("Cities");

                            xmlw.WriteStartElement("City");

                            xmlw.WriteAttributeString("Zip","201818");

 

                            xmlw.WriteStartAttribute("State",null);

                            xmlw.WriteEntityRef("I");

                            xmlw.WriteEndAttribute();

 

                            xmlw.WriteEntityRef("I-Capital");

 

                            xmlw.WriteEndElement();

                            xmlw.WriteEndElement();

 

                            xmlw.WriteEndDocument();

 

xmlw.Close();

 

输出的结果如下：

<?xml version="1.0" encoding="gb2312" standalone="yes" ?>

  <!DOCTYPE MyDef (View Source for full doctype...)>

- <Cities>

      <City Zip="201818" State="Italy">Rome</City>

  </Cities>

很明显，属性和元素的区别。
State="Italy"是属性定义，Rome属于元素定义也就是节点。
