Question

我试图计算Team Element中的值，抛出所有Xml节点并以此格式填充到List框：Team1，Count 3。 Thnx寻求帮助

    XmlNodeList nodeList = xmlDoc.GetElementsByTagName("Team");
        foreach (XmlNode xNode in nodeList)
        {
            foreach (var item in xNode)
            {
                lstRegPartiData.Items.Add(xNode.InnerText + item);   
            }
        }

这里我尝试按值计算元素。

这是我的xml模板。

           <Participants>
              <Participant>
                <DateTime>21.04.2018</DateTime>
                <FullName>N1</FullName>
                <Email>email@gmail.com</Email>

                <MainWeaponChrono>120-130 m\s</MainWeaponChrono>
                <WeaponClass>C1</WeaponClass>
                <Comment>Hello World</Comment>
              </Participant>
              <Participant>

                <Team>Team1</Team>
                <MainWeapon>T1</MainWeapon>
                <MainWeaponChrono>120-130 m\s</MainWeaponChrono>
                <WeaponClass>C1</WeaponClass>
                <Comment>My Comment</Comment>
              </Participant>
               <Participant>

                <DateOfBirth>00/00/1988</DateOfBirth>
                <Team>Team1</Team>
                <MainWeapon>T1</MainWeapon>
                <MainWeaponChrono>120-130 m\s</MainWeaponChrono>
                <WeaponClass>C1</WeaponClass>
                <Comment>Hello World</Comment>
              </Participant>
            </Participants>

Answer 1

如果我们假设您的xml类似于：

<Root>
<Team name="team1">
 <Participants>
              <Participant> 
              </Participant>
              <Participant>

              </Participant>
               <Participant>

              </Participant>
 </Participants>
</Team>
<Team name="team2">
 <Participants>
              <Participant> 
              </Participant> 
              <Participant> 
              </Participant>
 </Participants>
</Team>
</Root>

然后将您的代码更改为：

XDocument xdoc = XDocument.Load(@"your xml path");
var teams = xdoc.Descendants("Team");
foreach (XElement team in teams)
{
    var firstElement = team.Elements();//Get all elements, here is only one element
    var participants = firstElement.Elements();
    int teamCount = participants.Count();
    var teamName = team.FirstAttribute.Value;
    Console.Out.WriteLine("{0} contains {1} member(s)...", teamName, teamCount); 
}
Console.ReadLine();

注释：

1-每个xml文件必须不包含一个根元素，此处为<Root>。

2-我认为每个team元素中都有一个元素，因此team.Elements()会为您提供所有元素。

3-我认为每个名为team的{{1}}元素都有一个属性，因此name会为team.FirstAttribute.Value提供name元素，否则你应该使用类似team的内容来获取属性。

Answer 2

也许你可以做这样的事情

XmlDocument readDoc = new XmlDocument();
readDoc.Load(@"XML.xml");
var Node = readDoc.SelectNodes("Participants/Participant/Team");
Dictionary<string, int> teamList = new Dictionary<string, int>();
foreach (XmlNode n in Node)
{
    if (teamList.ContainsKey(n.InnerText))
        teamList[n.InnerText]++;
    else
        teamList.Add(n.InnerText, 1);
}

我知道它看起来不太好但是应该可行
