InnerText和InnerXml的区别
InnerText无格式显示里面的所有内容，InnerXml含有格式的显示；应该和InnerText和InnerHtml是一样的。
XmlDocument doc = new XmlDocument();
doc.LoadXml("<root>" +
"<elem>some text<child/>more text</elem>" +
"</root>");
XmlNode elem = doc.DocumentElement.FirstChild;
// Note that InnerText does not include the markup.
Console.WriteLine("Display the InnerText of the element...");
Console.WriteLine(elem.InnerText);
//来源MSDN
// InnerXml includes the markup of the element.
Console.WriteLine("Display the InnerXml of the element...");
Console.WriteLine(elem.InnerXml);
// Set InnerText to a string that includes markup.
// The markup is escaped.
elem.InnerText = "Text containing <markup/> will have char(<) and char(>) escaped.";
Console.WriteLine(elem.OuterXml);
// Set InnerXml to a string that includes markup.
// The markup is not escaped.
elem.InnerXml = "Text containing <markup/>.";
Console.WriteLine(elem.OuterXml);
Console.Read();
输出：
Display the InnerText of the element...
some textmore text
Display the InnerXml of the element...
some text<child />more text
<elem>Text containing <markup/> will have char(<) and char(>) escape
d.</elem>
<elem>Text containing <markup />.</elem>
