I want to fetch attributes from the different elements including the nested ones.我想从包括嵌套元素在内的不同元素中获取属性。 I want to create an object with the values.我想用这些值创建一个对象。
Main:主要的：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;
namespace Mini_Project_Tour_De_France.TourDeFranceModel
{
public class XmlParser
{
public string fileName { get; set; } = "Cycling.xml";
public List<Cyclist> participants { get; set; } = new List<Cyclist>();
public string typeOfSport { get; set; }
public XDocument doc { get; set; }
public DateTime startDate { get; set; }
public DateTime endDate { get; set; }
public XmlParser()
{
doc = XDocument.Load(fileName);
getParticipants();
getEventStartDate_EndDate();
getTypeOfSport();
}
The method PARSING XML:方法解析 XML：
public void getParticipants()
{
if (fileName != null)
{
IEnumerable<Cyclist> decendants = from c in doc.Descendants("event_participant")
select new Cyclist()
{
Name = c.Element("participant").Attribute("name").Value,
gender = c.Element("participant").Attribute("gender").Value,
type = c.Element("participant").Attribute("type").Value,
countryFK = int.Parse(c.Element("participant").Attribute("countryFK").Value),
enetID = int.Parse(c.Element("participant").Attribute("enetID").Value),
enetSportID = (c.Element("participant").Attribute("enetSportID").Value),
del = c.Element("participant").Attribute("del").Value,
n = int.Parse(c.Element("participant").Attribute("n").Value),
id = int.Parse(c.Element("participant").Attribute("id").Value),
// This ut is a dateType. It's an attribute inside the element <result> which is inside <results> which is inside <event_participant>.
//How can i get it?
ut = Convert.ToDateTime(c.Element("results").Element("result").Attribute("ut").Value),
// Same problem here.
rank = c.Element("results").Element("result").Attribute("result_code").Value
};
participants = decendants.ToList();
}
}
Here i'm trying to create a cyclist object with all the data it needs.在这里，我试图用它需要的所有数据创建一个骑自行车的对象。 I am having a hard time trying to explain what i want to happen.我很难解释我想要发生的事情。 Maybe one of you can see what i'm trying to do?也许你们中的一个人可以看到我在做什么？ If not, tell me and i will try and explain it better.如果没有，请告诉我，我会尝试更好地解释它。
Cylist class:圆柱类：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Mini_Project_Tour_De_France.TourDeFranceModel
{
public class Cyclist
{
public string Name { get; set; }
public string gender { get; set; }
public string type { get; set; }
public int countryFK { get; set; }
public string enetSportID { get; set; }
public int enetID { get; set; }
public int n { get; set; }
public string del { get; set; }
public DateTime ut { get; set; }
public int id { get; set; }
public string resultTime { get; set; }
public string rank { get; set; }
public override string ToString() {
return string.Format("Name: {0} gender: {1} type: {2}+ countryFK: {3} enetSportID: {4} enetID: {5} n: {6} del: {7} ut:{8} id:{9} resultTime:{10} rank: {11}"
,Name,gender,type,countryFK,enetSportID,enetID,n,del,ut,id,resultTime,rank)
;
}
}
}
Thanks!谢谢！ :) :)

Try following :尝试以下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication7
{
class Program
{
const string FILENAME = @"c:\temp\test.xml";
static void Main(string[] args)
{
new XmlParser(FILENAME);
}
}
public class Cyclist
{
public string Name { get; set; }
public string gender { get; set; }
public string type { get; set; }
public int countryFK { get; set; }
public int enetID { get; set; }
public string enetSportID { get; set; }
public string del { get; set; }
public int n { get; set; }
public int id { get; set; }
public DateTime ut { get; set; }
public List<Result> results { get; set; }
}
public class Result
{
public int event_participantsFK { get; set; }
public int result_typeFK { get; set; }
public string result_code { get; set; }
public string value { get; set; }
public string del { get; set; }
public int n { get; set; }
public DateTime ut { get; set; }
public int id { get; set; }
}
public class XmlParser
{
public List<Cyclist> participants { get; set; }
public string typeOfSport { get; set; }
public XDocument doc { get; set; }
public DateTime startDate { get; set; }
public DateTime endDate { get; set; }
public XmlParser(string fileName)
{
doc = XDocument.Load(fileName);
getParticipants();
//getEventStartDate_EndDate();
//getTypeOfSport();
}
public void getParticipants()
{
if (doc != null)
{
participants = doc.Descendants("event_participant").Select(c => new Cyclist() {
Name = (string)c.Element("participant").Attribute("name"),
gender = (string)c.Element("participant").Attribute("gender"),
type = (string)c.Element("participant").Attribute("type"),
countryFK = (int)c.Element("participant").Attribute("countryFK"),
enetID = (int)c.Element("participant").Attribute("enetID"),
enetSportID = (string)c.Element("participant").Attribute("enetSportID"),
del = (string)c.Element("participant").Attribute("del"),
n = (int)c.Element("participant").Attribute("n"),
id = (int)c.Element("participant").Attribute("id"),
ut = (DateTime)c.Element("participant").Attribute("ut"),
results = c.Descendants("result").Select(y => new Result() {
event_participantsFK = (int)y.Attribute("event_participantsFK"),
result_typeFK = (int)y.Attribute("result_typeFK"),
result_code = (string)y.Attribute("result_code"),

del = (string)y.Attribute("del"),
n = (int)y.Attribute("n"),
ut = (DateTime)y.Attribute("ut"),
id = (int)y.Attribute("id")
}).ToList()
}).ToList();
}
}
}
}
