Question

我有一个肥皂消息如下所示。我想只获取request元素及其子节点。

<?xml version="1.0" encoding="UTF-8" ?>

        </Inventory>
      </Inventories>
    </OTA_HotelInvCountNotifRQ>
  </soap:body>
</soap:envelope>

当我尝试反序列化上面的消息时，它会给我以下异常：

发生了'System.InvalidOperationException'类型的异常   System.Xml.dll但未在用户代码中处理

其他信息：XML文档中存在错误（2,2）。

这是我的Deserealize方法：

private OTA_HotelInvCountNotifRQ DeserializeResXMl(string xmlbody)
{

    OTA_HotelInvCountNotifRQ ret = null;

    if (xmlbody != null && xmlbody != string.Empty)
    {
        try
        {
            long TimeStart = DateTime.Now.Ticks;

            XmlSerializer serializer;
            serializer = new XmlSerializer(typeof(OTA_HotelInvCountNotifRQ));
            ret = (OTA_HotelInvCountNotifRQ)serializer.Deserialize(new StringReader(xmlbody));
        }
        catch (Exception e)
        {
           ret = null;
        }
   }
   return ret;
}

我该如何解决这个问题？

以下是使用XML Linq的解决方案

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

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);
            var ota_HotelInvCountNotifRQ = doc.Descendants().Where(x => x.Name.LocalName == "OTA_HotelInvCountNotifRQ").Select(y => new OTA_HotelInvCountNotifRQ()
            {
                echotoken = (string)y.Attribute("echotoken"),
                timeStampField = DateTime.Parse((string)y.Attribute("timestamp")),
                versionField = (decimal)y.Attribute("version"),
                sequencenmbr = (int)y.Attribute("sequencenmbr"),
                hotelCode = (string)y.Descendants().Where(z => z.Name.LocalName == "Inventories").FirstOrDefault().Attribute("HotelCode"),
                hotelName = (string)y.Descendants().Where(z => z.Name.LocalName == "Inventories").FirstOrDefault().Attribute("HotelName"),
                start = (DateTime)y.Descendants().Where(z => z.Name.LocalName == "StatusApplicationControl").FirstOrDefault().Attribute("Start"),
                end = (DateTime)y.Descendants().Where(z => z.Name.LocalName == "StatusApplicationControl").FirstOrDefault().Attribute("End"),
                invTypeCode = (string)y.Descendants().Where(z => z.Name.LocalName == "StatusApplicationControl").FirstOrDefault().Attribute("InvTypeCode"),
                _override = (Boolean)y.Descendants().Where(z => z.Name.LocalName == "StatusApplicationControl").FirstOrDefault().Attribute("Override"),
                countType = (int)y.Descendants().Where(z => z.Name.LocalName == "InvCount").FirstOrDefault().Attribute("CountType"),
                count = (int)y.Descendants().Where(z => z.Name.LocalName == "InvCount").FirstOrDefault().Attribute("Count"),
            }).FirstOrDefault();
        }
    }
    public class OTA_HotelInvCountNotifRQ
    {
        public string echotoken { get; set; }
        public DateTime timeStampField { get; set; }
        public decimal versionField { get; set; }
        public int sequencenmbr { get; set; }
        public string hotelCode { get; set; }
        public string hotelName { get; set; }

        public DateTime start { get; set; }
        public DateTime end { get; set; }
        public string invTypeCode { get; set; }
        public Boolean _override { get; set; }

        public int count { get; set; }
        public int countType { get; set; }
    }
}

Answer 3

我试图使用以下结构反序列化XML：

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soapenv:Body>
    <GetCategoryFeaturesResponse xmlns="urn:ebay:apis:eBLBaseComponents">
[...]
    </GetCategoryFeaturesResponse>
  </soapenv:Body>
</soapenv:Envelope>

问题似乎是xmlns声明，导致XmlSerializer导致所描述的错误。

我添加了一个XmlRootAttribute作为构造函数的参数，并删除了不需要的元素。可能不是最干净但快速的解决方案。

public GetCategoryFeaturesResponseType GetCategoryFeatures(int categoryId)
        {
            var apiCall = new GetCategoryFeaturesCall(ApiContext)
            {
                CategoryID = categoryId.ToString()
            };

            try
            {
                apiCall.GetCategoryFeatures();
            }
            catch (Exception e)
            {
                return null;
            }

            var response = apiCall.SoapResponse;

            if (response == null)
                return null;

            response = TrimXml(response, "<GetCategoryFeaturesResponse xmlns=\"urn:ebay:apis:eBLBaseComponents\">",
                "</GetCategoryFeaturesResponse>");

            var responseStream = Helpers.Serialization.CreateStream(response);

            var rootAttribute = new XmlRootAttribute()
            {
                ElementName = "GetCategoryFeaturesResponse",
                Namespace = "urn:ebay:apis:eBLBaseComponents",
                IsNullable = true
            };


            GetCategoryFeaturesResponseType categoryFeatures;
            try
            {
                categoryFeatures =
                    Helpers.Serialization.SerializeToModel<GetCategoryFeaturesResponseType>(responseStream,
                        rootAttribute);
            }
            catch (Exception e)
            {
                return null;
            }

            return categoryFeatures;
        }


private static string TrimXml(string origin, string begin, string end)
        {
            var startIndex = origin.IndexOf(begin, StringComparison.Ordinal);
            var endLength = origin.IndexOf(end, StringComparison.Ordinal);
            endLength = endLength - startIndex + end.Length;

            return origin.Substring(startIndex, endLength);
        }

XML文档中存在错误（2,2）：尝试反序列化此SOAP xml时？
