如何将平面重复 xml 属性读取到单独的对象中

Question

我有一个 XML 文件，其中包含一些我需要读入单独对象的结果。我的问题是数据包含在单个节点中。

我需要读取的属性也会根据不同的结果而变化，所以它不像使用TAKE之类的东西那么简单。

这是一个结果：

<AnalyteCode>HEM</AnalyteCode>
<AnalyteName>HEM</AnalyteName>
<Result>18.0</Result>
<ResultText>0</ResultText>

但是，这也是：

<AnalyteCode>ALP</AnalyteCode>
<AnalyteName>ALP SerPl-cCnc</AnalyteName>
<Result>52.0</Result>
<Units>U/L</Units>
<LowRange>20.0</LowRange>
<HighRange>150.0</HighRange>

为简洁起见，我省略了一些 XML

Answer 1

如果每个结果总是以一个属性开头（例如；"AnalyteCode"），那么您可以使用它作为 "starting" 分隔符来解析每个组。

我创建了一些示例代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Xml;

namespace Test_20191203
{
    public class LabResultItem
    {
        public string AnalyteCode { get; set; }
        public string AnalyteName { get; set; }
        public string Result { get; set; }
        public string ResultText { get; set; }
        public string Units { get; set; }
        public string LowRange { get; set; }
        public string HighRange { get; set; }
        public string Notes { get; set; }
    }

    public class Program
    {
        static void Main(string[] args)
        {
            string startProperty = nameof(LabResultItem.AnalyteCode);

            XmlDocument doc = new XmlDocument();
            doc.LoadXml(input);

            List<LabResultItem> results = new List<LabResultItem>();
            LabResultItem currentItem = new LabResultItem();
            foreach (XmlNode node in doc.SelectSingleNode("/LabResults/LabResult/LabResultItems/LabResultItem").ChildNodes)
            {
                if (node.Name == startProperty)
                {
                    results.Add(currentItem);
                    currentItem = new LabResultItem();
                }

                var prop = typeof(LabResultItem).GetProperty(node.Name);
                if(prop == null)
                {
                    throw new Exception($"Invalid node found in xml: '{node.Name}', property must be a part of {nameof(LabResultItem)}");
                }
                prop.SetValue(currentItem, node.InnerText, null);
            }

            foreach(var result in results)
            {
                // iterate through results
            }
        }

        const string input = @"<LabResults>
