Answer 1

已知有一个XML文件（bookstore.xml）如下：   
    
  <?xml   version="1.0"   encoding="gb2312"?>   
  <bookstore>   
      <book   genre="fantasy"   ISBN="2-3631-4">   
          <title>Oberon's   Legacy</title>   
          <author>Corets,   Eva</author>   
          <price>5.95</price>   
      </book>   
  </bookstore>   
      1、往<bookstore>节点中插入一个<book>节点：   
    
            
    
  XmlDocument   xmlDoc=new   XmlDocument();   
        xmlDoc.Load("bookstore.xml");   
        XmlNode   root=xmlDoc.SelectSingleNode("bookstore");//查找<bookstore>   
        XmlElement   xe1=xmlDoc.CreateElement("book");//创建一个<book>节点   
        xe1.SetAttribute("genre","李赞红");//设置该节点genre属性   
        xe1.SetAttribute("ISBN","2-3631-4");//设置该节点ISBN属性   
      
        XmlElement   xesub1=xmlDoc.CreateElement("title");   
        xesub1.InnerText="CS从入门到精通";//设置文本节点   
        xe1.AppendChild(xesub1);//添加到<book>节点中   
        XmlElement   xesub2=xmlDoc.CreateElement("author");   
        xesub2.InnerText="候捷";   
        xe1.AppendChild(xesub2);   
        XmlElement   xesub3=xmlDoc.CreateElement("price");   
        xesub3.InnerText="58.3";   
        xe1.AppendChild(xesub3);   
      
        root.AppendChild(xe1);//添加到<bookstore>节点中   
        xmlDoc.Save("bookstore.xml");

我现在是要在已有节点下插入子节点的内容哦
------------------------------------
非得一条一条写出来吗?不是已经告诉你创建节点.添加节点内容跟属性了吗?你获取节点之后用appendchild都不会吗?

Answer 3

目前对xml文档的操作不是很熟练,不过可以用另一种方法实现,先将此xml文件的内容存入一个dataSet中,然后遍历dataRow,这样你就能够修改了,等到你修改完了,然后在writeXML就行了,你要的效果肯定是能够实现的.也不是很麻烦啊 

Answer 4

可以用DOM+Xpath技术, 不用全部遍历

Answer 6

我的XML结构是从SQL数据库读出来的修改之后要写入SQL中哪位高手有实践经验 麻烦传授下哦

Answer 7

XmlDocument doc = new XmlDocument();
doc.LoadXml(strXml);XmlNodeList steps = doc.SelectNodes("/DataStore/Flows/Flow[@FlowKey='cslc']/Step");
foreach(XmlNode step in steps)
{
    if (step.Attributes["Name"] == "流程环节1")
    {
        SetNameAndNoInfo(step,"你要改的Name","你要改的No");    
    }
    if (step.Attributes["Name"] == "流程环节3")
    {
        SetNameAndNoInfo(step,"你要改的Name","你要改的No");    
    }
}
string outerXML = doc.OuterXml;
//把这个字符串传到数据库就OK~~~~~private void SetNameAndNoInfo(XmlNode step,string name,string no)
{
    XmlNode node1 = step.SelectSingleNode("Executes/Exceute/ExecutorName");    
    node1.InnerText = name;    
    XmlNode node2 = step.SelectSingleNode("Executes/Exceute/ExecutorNo"); 
    node2.InnerText = no;    
}这些基本的操作可以参考MSDN就可以了~~~~~
