通过标签读取XML并在foreach循环 例如通过XML标签写入

Question

读取XML：

<users> 
<user> 
    <id>12345567</id> 
    <name>Ronsna Stedinberg</name> 
</user> 
<user> 
    <id>12345568</id> 
    <name>Sonsna Dtedinberg</name> 
</user> 
</users> 

现在我想给一个标签保存到一个新的文件，其所有的子标签

Answer 1

这是你将如何循环用户节点

string xml = @"<users><user><id>12345567</id><name>Ronsna Stedinberg</name></user><user><id>12345568</id><name>Sonsna Dtedinberg</name></user></users>"; 
XmlDocument doc = new XmlDocument(); 
doc.LoadXml(xml); 

XmlNodeList nodeList = doc.SelectNodes("//users/user"); 
foreach (XmlNode node in nodeList) 
{ 
    string id = node.SelectSingleNode("id").InnerText; 
    string name = node.SelectSingleNode("name").InnerText; 
} 

Answer 2

一个LINQ到XML的方法：

// Assuming your xml is named data.xml 
XDocument xml = XDocument.Load("data.xml"); 

var tags = from x in xml.Descendants("user")      
       select new 
       { 
        id = x.Element("id").Value, 
        name = x.Element("name").Value 
       }; 

foreach (var tag in tags) 
{ 
    Console.WriteLine(tag.id); 
    Console.WriteLine(tag.name); 
}
