XmlDocument 从字符串或文件中读取 XML.

XmlDocument to read an XML from string or from file.

XmlDocument doc = new XmlDocument();
doc.Load("c:\temp.xml");

或

doc.LoadXml("<xml>something</xml>");

然后在它下面找到一个节点，就像这样

then find a node below it ie like this

XmlNode node = doc.DocumentElement.SelectSingleNode("/book/title");

或

foreach(XmlNode node in doc.DocumentElement.ChildNodes){
   string text = node.InnerText; //or loop through its children as well
}

然后像这样读取该节点内的文本

then read the text inside that node like this

string text = node.InnerText;

或读取属性

string attr = node.Attributes["theattributename"]?.InnerText

始终检查 Attributes["something"] 是否为 null，因为如果该属性不存在，它将为 null.

Always check for null on Attributes["something"] since it will be null if the attribute does not exist.
