使用 SOAP 信封和无效的 xsd 地址反序列化 XML 文件

问题描述 投票：0回答：1

我想反序列化这种具有 SOAP 信封和标头中不再存在的无效 .xsd 地址的 XML 文件 (finvoiceack.xsd)。想要在我的 C# 代码中将节点获取到数据集或自己的变量中。但是我在 XML 文件中收到关于无效前缀或错误类型的错误消息。

这里是 XML 文件的示例：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:eb="http://www.oasis-open.org/committees/ebxml-msg/schema/msg-header-2_0.xsd" xmlns:spy="#this address doesn't work anymore#" xmlns:xlink="http://www.w3.org/1999/xlink">

这是我的功能：

        private static void DeserializeXmlFileToList()
        {
            var xmlSerializer = new XmlSerializer(typeof(ACKFile));
       
            using(var reader = new StreamReader(@"C:\ACK\test1.xml")) 
            {
                var ACKFile = (List<ACKFile>)xmlSerializer.Deserialize(reader);
            }
        }

这是我的模型还没有准备好，但我认为如果我有有效的 XML 文件它应该可以工作：

    [Serializable]
    [XmlRoot(Namespace = "example.org/eb", ElementName = "Acknowledgement")]
    public class ACKFile
    {
        [XmlElement(Namespace = "example.org/eb", ElementName = "From")]
        public string From { get; set; }

        [XmlElement(Namespace = "example.org/eb", ElementName = "To")]
        public string To { get; set; }

        [XmlElement(ElementName = "MessageData")]
        public string MessageData { get; set; }

        [XmlElement(ElementName = "Reason")]
        public string Reason { get; set; }
    }

剥离soap header后，可以反序列化为Finvoiceack模型。

我使用 Xml2CSharp 创建模型。我还必须将编码从 ISO-8859-15 更改为 ISO-8859-1 否则我会遇到异常：

System.InvalidOperationException: There is an error in XML document (1, 31).

 ---> System.Xml.XmlException: System does not support 'ISO-8859-15' encoding. Line 1, position 31.

 ---> System.ArgumentException: 'ISO-8859-15' is not a supported encoding name. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method. (Parameter 'name')

我希望这能有所帮助（为可视化添加了 json 序列化）：

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using System.Text.Json;
using System.Xml;
using System.Xml.Serialization;
using Xml2CSharp;

var xml = """

DeserializeXmlFileToList(xml);
