Question

<?xml version="1.0" standalone="yes"?>
<cells>
  <cell>
    <cell_id>dtxd</cellid>
    <cell_name></cellname>
    <scan_internal>300000</scan_internal>
    <cell_local>0</cell_local>
    <cell_value>ON</cell_value>
  </cell>
   <cell>
    <cell_id>ssdesdl</cellid>
    <cell_name></cellname>
    <scan_internal>400000</scan_internal>
    <cell_local>0</cell_local>
  </cell>
 </cells>
。我要读取scan_internal节点的值，如何读取？ 谢谢！

Answer 1

这种格式可以读取到datateble里面去

Answer 2

创建xml对象
读取xml
循环读取xml对象的节点
判断节点名 
得到相应结果

Answer 3

xmlDocument 里有个 selectNodes吧直接写  名字就会返回一个Nodelist对象 貌似可以

Answer 4

            XmlDocument doc = new XmlDocument();
            doc.Load("c:\\要读取的xml.xml");
            XmlNodeList nodelist = doc.SelectNodes("cells/cell/scan_internal");            foreach (XmlNode node in nodelist)
            {
                Console.WriteLine(node.InnerText);
            }

Answer 5

直接读到dataset里不久可以了吗 
dateSet.ReadXml ( “xml文件的路径”);
                
dataTable = dateSet.Tables [ 0 ]; 

Answer 6

string str="<?xml version="1.0" standalone="yes"?> ";
str+="<cells> ";
str+="<cell> ";
str+="     <cell_id>dtxd </cellid> ";
str+="     <cell_name> </cellname> ";
str+="     <scan_internal>300000 </scan_internal> ";
str+="     <cell_local>0 </cell_local> ";
str+="     <cell_value>ON </cell_value> ";
str+="   </cell> ";
str+="    <cell> ";
str+="     <cell_id>ssdesdl </cellid> ";
str+="     <cell_name> </cellname> ";
str+="     <scan_internal>400000 </scan_internal> ";
str+="     <cell_local>0 </cell_local> ";
dtr+="   </cell> ";
dtr+=  </cells> ";XmlDocument doc = new XmlDocument();
doc.LoadXml("c:\\要读取的xml.xml");
XmlNodeList nodelist = doc.SelectNodes("cells/cell/scan_internal");
foreach (XmlNode node in nodelist)
{
   Console.WriteLine(node.InnerText);
}

不好意思,发错了
string str=" <?xml version="1.0" standalone="yes"?> "; 
str+=" <cells> "; 
str+=" <cell> ";

str+="      <cell_local>0  </cell_local> "; 
dtr+="    </cell> "; 
dtr+=   </cells> "; XmlDocument doc = new XmlDocument(); 
doc.LoadXml(str); 
XmlNodeList nodelist = doc.SelectNodes("cells/cell/scan_internal"); 
foreach (XmlNode node in nodelist) 
{ 
   Console.WriteLine(node.InnerText); 
}
