计算XML元素值

Question

Im试图对Team Element中的值进行计数时，会抛出所有Xml节点，并以以下格式将其填充到“列表”框中：Team1，Count3。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);   

            }

        }

我在这里尝试按值计算元素。

这是我的xml模板。

Answer 1

如果我们假设您xml是这样的：<Root><Team name="team1">&nbsp;<Participants>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <Participant>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </Participant>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <Participant>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </Participant>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<Participant>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </Participant>&nbsp;</Participants></Team><Team name="team2">&nbsp;<Participants>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <Participant>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </Participant>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <Participant>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </Participant>&nbsp;</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){&nbsp; &nbsp; var firstElement = team.Elements();//Get all elements, here is only one element&nbsp; &nbsp; var participants = firstElement.Elements();&nbsp; &nbsp; int teamCount = participants.Count();&nbsp; &nbsp; var teamName = team.FirstAttribute.Value;&nbsp; &nbsp; Console.Out.WriteLine("{0} contains {1} member(s)...", teamName, teamCount);&nbsp;}Console.ReadLine();笔记：1-每个xml文件中最多只能有一个根元素，这里是<Root>。2-我认为每个team元素中只有一个元素，所以team.Elements()给您所有元素。3-我想每个team命名name的元素都有一个属性，所以team.FirstAttribute.Value给您元素的nameof team，否则您应该使用类似team.Attributes("name")get属性的方法。
