找不到元素声明 'xtce:SpaceSystem'

Question

我创建了以下基于 XTCE 标准的 XML 文件。但是，当我尝试验证它时，我看到一条错误消息，

Cannot Find The Declaration Of Element 'xtce:SpaceSystem'., Line '3', Column '81'

我不明白为什么，因为 SpaceSystem 元素作为根元素是 XSD 模式文件和 XTCE 文档的一部分。元素的头部或link到XSD方案是否有问题？以及如何更新文件以使其有效？

Answer 1

两个问题¹ 正在阻止 XML 与 XSD 相关联：

xsi:schemaLocation 的值应该是 space-separated 对 XML 命名空间及其关联的 XSD URI，
您的 XML 根元素的命名空间必须与管理 XSD.
的目标命名空间相匹配

所以改变

xsi:schemaLocation="https://www.omg.org/spec/XTCE/20180204/SpaceSystem.xsd">

到

xsi:schemaLocation="http://www.omg.org/spec/XTCE/20180204
                    https://www.omg.org/spec/XTCE/20180204/SpaceSystem.xsd">

提示验证器在 https://www.omg.org/spec/XTCE/20180204/SpaceSystem.xsd 中查找 http://www.omg.org/spec/XTCE/20180204 命名空间中的组件。

并改变

xmlns:xtce="http://www.omg.org/space/xtce"

到

xmlns:xtce="http://www.omg.org/spec/XTCE/20180204"

将根元素放置在管理 XSD 的目标命名空间中。

Answer 2

正如@kjhughes 正确指出的那样，命名空间处理不正确。

我调整了你的 XML 命名空间声明。

它仍然有一些错误。但现在您可以轻松修复它们。
