C#操作Xml节点

见过不少人、经过不少事、也吃过不少苦,感悟世事无常、人心多变,靠着回忆将往事串珠成链,聊聊感情、谈谈发展,我慢慢写、你一点一点看......

1、增加节点

public static bool AppendChild(string filePath, string xPath, XmlNode xmlNode){
  
  	try	{
  
  		XmlDocument doc = new XmlDocument();		doc.Load(filePath);		XmlNode xn = doc.SelectSingleNode(xPath);		XmlNode n = doc.ImportNode(xmlNode, true);		xn.AppendChild(n);		doc.Save(filePath);		return true;	}	catch	{
  
  		return false;	}}

2、修改节点

public static bool UpdateNodeInnerText(string filePath, string xPath, string value){
  
  	try	{
  
  		XmlDocument doc = new XmlDocument();		doc.Load(filePath);		XmlNode xn = doc.SelectSingleNode(xPath);		XmlElement xe = (XmlElement)xn;		xe.InnerText = value;		doc.Save(filePath);	}	catch	{
  
  		return false;	}	return true;}

3、查询节点

public static XmlNodeList ReadNodes(string filePath, string xPath){
  
  	try	{
  
  		XmlDocument doc = new XmlDocument();		doc.Load(filePath);		XmlNode xn = doc.SelectSingleNode(xPath);		XmlNodeList xnList = xn.ChildNodes;  		return xnList;	}	catch	{
  
  		return null;	}}
