我正在尝试使用 kSoap2 将 Android 应用程序与 SOAP 网络服务集成。我设法发出请求并取回一些数据，但是当响应解析发生时，我有以下 RuntimeException：

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

事实上，在响应中，我有 2 个类型不同但 id 属性值相同的元素。

<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">

和：

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

我自己不开发 SOAP Web 服务，所以我告诉开发人员我不明白这怎么可能，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，这是可能的，因为属性“id”不是数据类型“ID”而是数据类型“URN”。属性是指注册表中的唯一 id，它不是它自己的元素的 id。在此应用程序中，我们默认使用 ebXML 注册表信息模型版本 3.0。您可以在 oasis 的文档中找到更多信息和示例： https ://docs.oasis-open.org/regrep/v3.0/specs/regrep-rim-3.0-os.pdf

现在我很困惑。那么在一个 XML 文档中是否可以存在多个具有相同 ID 的元素？如果是的话，有没有办法配置 kSOAP2 让它忽略那个双 ID？

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。

我不知道您用来进行解析的库，所以我不知道是否可以禁用验证或忽略验证错误。
