如何创建这样的XML文档？
<body>
<level1>
<level2>text</level2>
<level2>other text</level2>
</level1>
</body>
使用XmlDocument在C#

关于什么:
#region Using Statements
using System;
using System.Xml;
#endregion
class Program {
static void Main( string[ ] args ) {
XmlDocument doc = new XmlDocument( );
//(1) the xml declaration is recommended, but not mandatory
XmlDeclaration xmlDeclaration = doc.CreateXmlDeclaration( "1.0", "UTF-8", null );
XmlElement root = doc.DocumentElement;
doc.InsertBefore( xmlDeclaration, root );
//(2) string.Empty makes cleaner code
XmlElement element1 = doc.CreateElement( string.Empty, "body", string.Empty );
doc.AppendChild( element1 );
XmlElement element2 = doc.CreateElement( string.Empty, "level1", string.Empty );
element1.AppendChild( element2 );
XmlElement element3 = doc.CreateElement( string.Empty, "level2", string.Empty );
XmlText text1 = doc.CreateTextNode( "text" );
element3.AppendChild( text1 );
element2.AppendChild( element3 );
XmlElement element4 = doc.CreateElement( string.Empty, "level2", string.Empty );
XmlText text2 = doc.CreateTextNode( "other text" );
element4.AppendChild( text2 );
element2.AppendChild( element4 );
doc.Save( "D:\\document.xml" );
}
}
(1)有效的XML文件是否需要xml声明？
(2)String.Empty和""(空字符串)有什么区别？
结果是:
<?xml version="1.0" encoding="UTF-8"?>
<body>
<level1>
<level2>text</level2>
<level2>other text</level2>
</level1>
</body>
但我建议你使用LINQ to XML,它更简单,更易读,如下所示:
#region Using Statements
using System;
using System.Xml.Linq;
#endregion
class Program {
static void Main( string[ ] args ) {
XDocument doc = new XDocument( new XElement( "body",
new XElement( "level1",
new XElement( "level2", "text" ),
new XElement( "level2", "other text" ) ) ) );
doc.Save( "D:\\document.xml" );
}
}
