XML文档中存在错误（0,0）

标签： c# xml soap ssis deserialization

我花了无数个小时研究这个问题，并尝试了很多不同的事情。一些背景...我在SSIS模块中使用C＃代码来尝试反序列化SOAP XML流。我以前能够反序列化XML流，但是这个比我之前参与的那些要复杂得多。

我已经确认我用来填充我的流的字符串对于结果是正确的，并且我到达了我的绳子的末尾。

这是我用来尝试反序列化的方法。您可以看到我已经包含了几个已注释掉的部分，以展示我用来尝试实现此功能的其他一些方法：

private Envelope GetWebServiceResultFromStream(StreamReader str)
{

    bool b = true;
    Envelope xmlResponse = null;
    String xmlPayload = "";

   //Deserialize our XML
    try
    {
        //System.Runtime.Serialization.Formatters.Soap.SoapFormatter soapFormatter = new System.Runtime.Serialization.Formatters.Soap.SoapFormatter();

        //using (Stream savestream = str.BaseStream)
        //{
        //    xmlResponse = (Envelope)soapFormatter.Deserialize(savestream);
        //}


        System.Xml.Serialization.XmlSerializer sr = new System.Xml.Serialization.XmlSerializer(typeof(Envelope));

        using (Stream savestream = str.BaseStream)
        {
            StreamReader streamreader = new StreamReader(savestream, Encoding.UTF8);
            xmlPayload = streamreader.ReadToEnd();

            //xmlPayload = System.Security.SecurityElement.Escape(xmlPayload);

            //xmlPayload = xmlPayload.Replace("&", "&");
            //xmlPayload = xmlPayload.Replace("&", "&");
            xmlPayload = xmlPayload.Replace("'", "'");
            //xmlPayload = xmlPayload.Replace("soap:Envelope", "Envelope");


            File.WriteAllText(@"myxml.xml",xmlPayload);



            byte[] byteArray = Encoding.UTF8.GetBytes(xmlPayload);
            MemoryStream secondstream = new MemoryStream(byteArray);
            secondstream.Position = 0;

            xmlResponse = sr.Deserialize(secondstream) as Envelope;

            //xmlResponse = (Envelope)DeserializeFromXml<Envelope>(xmlPayload);

            //XmlDocument doc = new XmlDocument();
            //doc.Load(secondstream);
            //XmlNodeReader reader = new XmlNodeReader(doc);
            //using (reader)
            //{
            //    xmlResponse = sr.Deserialize(reader) as Envelope;
            //}


            //System.Runtime.Serialization.Formatters.Soap.SoapFormatter soapFormatter = new System.Runtime.Serialization.Formatters.Soap.SoapFormatter();


            //xmlResponse = (Envelope)soapFormatter.Deserialize(secondstream);


        }

        //XmlDocument xmlSoapRequest = new XmlDocument();
        //using (Stream savestream = str.BaseStream)
        //{
        //    using (StreamReader readStream = new StreamReader(savestream, Encoding.UTF8))
        //    {
        //        xmlSoapRequest.Load(readStream);
        //        xmlPayload = xmlSoapRequest.SelectSingleNode("//Envelope/Body/GetRequisitionByDateResponse/").InnerText;
        //    }
        //}

    }
    catch (Exception ex)
    {
        DumpException(ex);
        this.ComponentMetaData.FireInformation(54, "", "Failed to deserialize: " + ex.Message + " Inner: " + ex.InnerException + " Source: " + ex.Source, "", 43, ref b);
    }

    return xmlResponse;

}

public static T DeserializeFromXml<T>(string xml)
{
    T result;

    var ser = new XmlSerializer(typeof(T));
    using (var tr = new StringReader(xml))
    {
        result = (T)ser.Deserialize(tr);
    }
    return result;
}

我正在使用通过将响应提供给XML到C＃转换器（http://xmltocsharp.azurewebsites.net/）而生成的c＃类。不幸的是，似乎这些类太复杂而无法放在这里（帖子有30k字符限制），所以它已被粘贴在这里： http://txt.do/d91eo

我还贴了一个示例回复： http://txt.do/d91eb

我已经咨询了wsdl，看起来许多DateTime字段正在通过转换器读取为字符串。我不确定这是否是一个问题，但我已尽力替换这些数据类型并且错误仍然存​​在。

以下是我的错误的屏幕截图： http://imgur.com/a/objJq

我尝试过的其他事情：

替换整个xml文档中的无效字符（我发现它已经这样做了，除了一些“'”字符的情况）。

删除了名称空间。

将所有类标记为Serializable。

SSIS中的Web服务对象（抛出错误并且不允许我输入要发送的任何变量）。

使用返回结果的多个变体重新生成类列表。

答案 0 :(得分：1)

找到它

首先将UTF8添加到StreamReader：new StreamReader（FILENAME，Encoding.UTF8）;

这是你的根类

 [XmlRoot(ElementName = "Envelope", Namespace = "http://www.w3.org/2003/05/soap-envelope")]
    public class Envelope
    {
    }

这是你的第一行XML 

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

比较命名空间

答案 1 :(得分：1)

以下代码正在运行，没有例外。由于尺寸限制，我不能包括类。注意Class Envelope的命名空间我用“/”替换了“ - ”。构造类Envelope但所有属性都为null，因为命名空间与xml不一致。
