用这个标示怎么判断？

Answer 1

用这个<Number>1</Number>去判断

Answer 2

为什么不将数据读到table 列表之类的里面去，然后再通过条件查找，筛选要比处理这个XML好吧。

Answer 3

XmlDocument doc = new XmlDocument();
doc.LoadXml("XML文件");
 pram1 = doc.SelectSingleNode("/Number"); 

Answer 4

你这个xml是不能直接创建xml对象的，必须有跟节点。
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.LoadXml(@"<Root>
  <DiscountInfo>
  <Number>1</Number>
  <FlightNO>ZH9683</FlightNO>
  <Class>Z</Class>
  <Discount>55</Discount>
  <Nums>A</Nums>
  <Price>380</Price>
  <ClassType>常规</ClassType>
  <PolicyID />
  <IsPAT>0</IsPAT>
  <PATCmd />
  <Area />
  <IsChild>0</IsChild>
  </DiscountInfo>
  <DiscountInfo>
  <Number>1</Number>
  <FlightNO>ZH9683</FlightNO>
  <Class>G</Class>
  <Discount>51</Discount>
  <Nums>A</Nums>
  <Price>350</Price>
  <ClassType>常规</ClassType>
  <PolicyID />
  <IsPAT>0</IsPAT>
  <PATCmd />
  <Area />
  <IsChild>0</IsChild>
  </DiscountInfo>
  <DiscountInfo>
  <Number>2</Number>
  <FlightNO>ZH9683</FlightNO>
  <Class>V</Class>
  <Discount>45</Discount>
  <Nums>A</Nums>
  <Price>310</Price>
  <ClassType>常规</ClassType>
  <PolicyID />
  <IsPAT>0</IsPAT>
  <PATCmd />
  <Area />
  <IsChild>0</IsChild>
  </DiscountInfo>
</Root>");
            XmlNodeList nodes = xmlDoc.SelectNodes("//DiscountInfo[./Number = '1']");
            foreach (XmlNode node in nodes)
            {
                MessageBox.Show(node.InnerXml);
            }

Answer 6

其实 我就是想取DiscountInfo不同<Number>1</Number>节点下Price、
我想先取所有<Number>1</Number> 的字符串
str   //这里不知道怎么取了
然后
string a = XDocument.Parse(str).Descendants("DiscountInfo").OrderBy(x => Convert.ToInt32(x.Element("Price").Value)).First().ToString();
就可以了

Answer 7

DiscountInfo不同<Number>1</Number>节点下最小Price、

Answer 8

用Xpath直接找Price节点不就好了吗？
XmlNodeList nodes = xmlDoc.SelectNodes("//DiscountInfo[./Number = '1']/Price");再对这个nodes遍历取最小值即可。
