使用 XSD 验证 XML - 意外的子错误

如何解决使用 XSD 验证 XML - 意外的子错误

我是 XML 验证的新手，但遇到了一个我不明白的问题。 我正在使用 Python xmlschema 库根据我使用 MS xsd 工具生成的 XSD 文件验证 XML 文件。在创建了许多运行良好的 XSD 模式后，我在最新的 XSD 中遇到了以下问题

XML 文件 C:/Users/xxxxxxxxxx/XMLfiles/AdamIntegration/google\RLS22770.manifest.xml 无效：验证 与 XsdGroup(model='sequence',出现=[1,1]):

原因：在位置 1 处带有标签“app1:displayName”的意外子级。 需要标记 mstns:displayName。

架构：

实例：

首映

路径：/manifest:MediaManifest/manifest:Source/manifest:ServiceProvider

我该如何解决这个错误？

更新：它似乎在 http://www.movielabs.com/schema/manifest/v1.8/manifest 中寻找“displayName”，而据我所知，它实际上在 http://www.movielabs.com/schema/md/v2.7/md

XSD 文件 #1 episode_manifest.xsd

  </xs:element>
  <xs:element name="Format" msdata:Prefix="md" type="xs:string" fixed="SCC" />
  <xs:element name="Purpose" msdata:Prefix="md" type="xs:string" fixed="thumbnail" />
  <xs:element name="Width" msdata:Prefix="md" type="xs:string" />
  <xs:element name="Height" msdata:Prefix="md" type="xs:string" />
  <xs:element name="country" msdata:Prefix="md" type="xs:string" />
</xs:schema>

解决方法

md:DisplayName 元素显然位于错误的命名空间中。

您没有显示足够的架构让我们知道它应该在哪个命名空间中：我们需要查看包含 targetNamespace 的 elementFormDefault 和 xs:schema 属性元素。
