Question

我正在尝试使用kSoap2将Android应用程序与SOAP Web服务集成。我设法发出一个请求并获取一些数据，但是当响应解析发生时，我有以下RuntimeException：

W/System.err: java.lang.RuntimeException: double ID

实际上，在响应中，我有2个元素，它们的类型不同，但其id属性的值相同。

<ExtrinsicObject home="urn:oid:1.3.6.1.4.1.48336.1" id="urn:uuid:3468543d-5033-4d6b-86a5-f8a52fd0070e"
    isOpaque="false"
    lid="urn:uuid:3468543d-5033-4d6b-86a5-f8a52fd0070e"
    mimeType="text/xml"
    objectType="urn:uuid:7edca82f-054d-47f2-a032-9b2a5b5186c1"
    status="urn:oasis:names:tc:ebxml-regrep:StatusType:Approved">

并且：

<ObjectRef home="urn:oid:1.3.6.1.4.1.48336.1"
    id="urn:uuid:3468543d-5033-4d6b-86a5-f8a52fd0070e" />

我不是自己开发SOAP Web服务，所以我告诉开发人员，我不知道那是不可能的，因为我认为XML规范本身说ID必须是唯一的。这就是他们的回答：

在这种情况下，可能是因为方言“ id”不是数据类型为“ ID”，但数据类型为“ URN”。占卜者指的是注册表中的唯一ID，它不是其自身元素的ID。在此应用程序中，我们使用ebXML注册信息模型默认为3.0版。您可以在以下位置找到更多信息和示例绿洲文件： https://docs.oasis-open.org/regrep/v3.0/specs/regrep-rim-3.0-os.pdf

现在我很困惑。那么在XML文档中是否可以有多个具有相同ID的元素？如果是的话，有没有一种方法可以配置kSOAP2使其忽略该双重ID？

Answer 1

具有重复ID值的XML文档格式正确，但无效。如果XML解析器作为非验证解析器运行，它将成功读取此类文档。

我不知道您要使用哪个库来进行解析，所以我不知道是否可以禁用验证或忽略验证错误。

XML文档是否可以包含2个具有相同ID的元素？
