XMLSerializer 无法反序列化 xml 文档

发布于 2024-09-29 02:45:13 字数 6488 浏览 8 评论 0原文

我是 C# 的新手。我有一个 java REST 服务，它返回 xml 响应，我正在尝试使用 C# XmlSerializer 反序列化 xml 文档。下面粘贴了示例 xml 文档响应。

<?xml version="1.0" encoding="UTF-8"
 standalone="yes" ?>  <ns2:Document
 xmlns:ns2="http://hxps.honeywell.com/model/impl"
 xmlns:ns3="http://hxps.honeywell.com/datatypes/impl"
 type="PS">
 <docId>SamplePSDocument1</docId> 
 <fields
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:ns5="http://jaxb.dev.java.net/array"
 xsi:type="ns5:anyTypeArray">   <item
 xsi:type="ns3:scalarFieldImpl"
 key="Name">
      <value xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xsi:type="xs:string">HXPS A4</value>
 </item>   <item
 xsi:type="ns3:scalarFieldImpl"
 key="Creation Date">
       <value xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xsi:type="xs:string">20 April
 2007</value>    </item> </fields>
 <id>fb92f871-1f3d-4fa4-ba24-5ae3af0a493f</id>
 <revision>1-c75f688e212fb5341ebdbd22a3867c14</revision>

 - <version>   <majorVersionNumber>1</majorVersionNumber>
 <minorVerisonNumber>5</minorVerisonNumber>
 </version> </ns2:document>

当我将此 xml 文档反序列化为 Document 对象时，它工作正常。我的文档类粘贴在下面

        set
        {
            this._id = value;
        }
    }
}
}

在我的主程序中，当我尝试

Array fields = (Array)doc.Fields;

在服务器端 java REST 服务实现中时，我得到一个 xmlNodes 数组，字段实际上是一个数组列表，其中包含接口的三个实现的实例。 （列表可能包含 ScalarFieldImpl 或 ArrayFieldImpl，它们是自定义业务对象）。

我想使用 XmlSerializer 将此 xml 字段反序列化为 ScalarFieldImpl 或 ArrayFieldImpl。我想知道是否可以？如果是这样，我该怎么做？

I am a newbie to C#. I have a java REST service which returns a xml response and I am trying to deserialize the xml document using C# XmlSerializer. A sample xml document response is pasted below.

<?xml version="1.0" encoding="UTF-8"
 standalone="yes" ?>  <ns2:Document
 xmlns:ns2="http://hxps.honeywell.com/model/impl"
 xmlns:ns3="http://hxps.honeywell.com/datatypes/impl"

 <fields
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:ns5="http://jaxb.dev.java.net/array"
 xsi:type="ns5:anyTypeArray">   <item
 xsi:type="ns3:scalarFieldImpl"
 key="Name">
      <value xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xsi:type="xs:string">HXPS A4</value>
 </item>   <item

It works fine when I deserialize this xml document into Document object. My document class is pasted below

    {
        get
        {
            return this._revision;
        }
        set
        {
            this._revision = value;
        }
    }
    /// <summary>
    ///  (no documentation provided)
    /// </summary>
    [System.Xml.Serialization.XmlElementAttribute(ElementName = "id", Namespace = "")]
    [System.Xml.Serialization.SoapElementAttribute(ElementName = "id")]
    public string Id
    {
        get
        {
            return this._id;
        }
        set
        {
            this._id = value;
        }
    }
}
}

In my main program, I get an array of xmlNodes when I try

Array fields = (Array)doc.Fields;

In the server side java REST service implementation, fields is actually a arraylist which will contain instances of three implementations of an interface. (List may contain ScalarFieldImpl or ArrayFieldImpl which are custom business objects).

I want to deserialize this xml fields into ScalarFieldImpl or ArrayFieldImpl using XmlSerializer. I want to know whether it is possible? If so, how do I do that?

据我所知，ootb xml（反）序列化程序不可能做到这一点，我认为您必须 编写您自己的 XmlSerializer。或者尝试使用 LINQ to XML。

As far as I know this isn't possible with the ootb xml (de-)serializer, I think you'll have to write your own XmlSerializer. Or try to use LINQ to XML.

我得到了这个工作。我在 PSDocument 类中做了一些更改。

私有对象_fields； ->私有ArrayList_fields；

我还更改了 get/set 方法并添加了新的元数据

[System.Xml.Serialization.XmlArray(ElementName = "fields", Namespace = "")]
[System.Xml.Serialization.XmlArrayItem(ElementName="item")]

公共 ArrayList 字段
{
得到
{
返回这个._fields；
}
放
{
this._fields = 值；
}
以前，

我的 PSDocument 类中有以下几行

[System.Xml.Serialization.XmlElementAttribute(ElementName = "fields", Namespace = "")]
[System.Xml.Serialization.SoapElementAttribute(ElementName = "字段")]
公共对象字段
{
得到
{
返回这个._fields；
}
放
{
this._fields = 值；
}
因此

，在反序列化 PSDocument 中的字段时，我得到一个以项目作为元素的数组列表。
希望这对某人有帮助。

I got this working. I did few changes in my PSDocument class.

private object _fields; -> private ArrayList _fields;

Also I changed get/set method and added new metadata

[System.Xml.Serialization.XmlArray(ElementName = "fields", Namespace = "")]
[System.Xml.Serialization.XmlArrayItem(ElementName="item")]

public ArrayList Fields
{
get
{
return this._fields;
}
set
{
this._fields = value;
}
}

Previously I had the following lines in my PSDocument class

[System.Xml.Serialization.XmlElementAttribute(ElementName = "fields", Namespace = "")]
[System.Xml.Serialization.SoapElementAttribute(ElementName = "fields")]
public object Fields
{
get
{
return this._fields;
}
set
{
this._fields = value;
}
}

So while deserializing fields in PSDocument, I get an arraylist with items as elements.
Hope this helps someone.
