放分求一个XML遍历操作的最基础例子,谢谢大家!!
<?xml version="1.0" encoding="UTF-8" ?> 
<response>
<result>
  <Acc>
  <row id="1">
  <fie value="f1">a1</fie> 
  <fie value="f2">a2</fie>
  </row>
  <row id="2">
  <fie value="f1">b1</fie> 
  <fie value="f2">b2</fie>
  </row>
  ……
  </Acc>
</result>
</response>
以上是XML文档,要求遍历每个row,把row下的每个fie节点value值为"f2"的值如"a2,b2"等提取出来放到字符串中,如str = "a2,b2,……"

麻烦各位给个例子,谢谢了!!!!!

------解决方案--------------------
StringBuilder build = new StringBuilder ();
XmlDocument doc = new XmlDocument ();
doc.load(@"D:\1.xml");
XmlNodeList list = doc.DocumentElement.GetElementByName("row");
for(int i=0;i<list.count;i++)
{
for(int j=0;j<list[i].ChildNodes.count ;j++)
{
if(list[i].ChildNodes[j].Attributs["value"].value="f2")
{
build.Append( list[i].ChildNodes[j].innerText);
build.Append(","); 
}
}

}
String s = build.ToString();

C# code

            string str = @"<?xml version=""1.0"" encoding=""UTF-8"" ?>
<response>
<result>
  <Acc>
    <row id=""1"">
      <fie value=""f1"">a1 </fie>
      <fie value=""f2"">a2 </fie>
    </row>
    <row id=""2"">
      <fie value=""f1"">b1 </fie>
      <fie value=""f2"">b2 </fie>
    </row>
  </Acc>
</result>
</response> ";
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(str);
            StringBuilder sb = new StringBuilder();
            foreach(XmlNode rowNode in doc.GetElementsByTagName("row"))
            {
                if (rowNode.HasChildNodes)
                {
                    foreach (XmlNode fieNode in rowNode.ChildNodes)
                    {
                        if (fieNode.Name == "fie" && fieNode.Attributes["value"].Value == "f2")
                            sb.Append(fieNode.InnerText + ",");
                    }
                }
            }
            Console.WriteLine(sb.ToString().TrimEnd(','));
