可是我要用xmldocument.load()
方法load这个xml文件阿
可使我把<?xml-stylesheet?>先写进去后
load的时候就抱错说是无法解析<?xml-stysheet?>指令
能不能先 load后
然后把 <?xml-stylesheet?>指令写进去呢
谢谢立刻揭帖

关键的地方在于： Writer.WriteProcessingInstruction("Read","Information");//写出在名称和文本之间带有空格的处理指令，可用来指出用什么文件来解析此XML

/* String PItext="type='text/xsl' href='book.xsl'";
writer.WriteProcessingInstruction("xml-stylesheet", PItext);

* */

XmlTextWriter Writer=new XmlTextWriter("sample.xml",System.Text.Encoding.Default);//会以gb2312的格式写XML
Writer.Formatting=Formatting.Indented;//设置缩进

Writer.WriteStartDocument();
Writer.WriteComment("特别说明：这是使用ASP.NET的好处呀！");//写注译
Writer.WriteProcessingInstruction("Read","Information");//写出在名称和文本之间带有空格的处理指令，可用来指出用什么文件来解析此XML

/* String PItext="type='text/xsl' href='book.xsl'";
writer.WriteProcessingInstruction("xml-stylesheet", PItext);

* */

Writer.WriteStartElement("i","Info","urn:Info");

Writer.WriteStartElement("Name","");
Writer.WriteString("黄海呀！");
Writer.WriteEndElement();

Writer.WriteStartElement("Address","");
Writer.WriteString("深圳市南山区前海路北大附中南山分校");
Writer.WriteEndElement();

Writer.WriteEndDocument();

Writer.Close();
