XML 模式命名空间 - 出现验证错误

Question

我正在尝试根据架构验证 XML 文件。我对此非常陌生，但我几乎 100% 都与命名空间有关。问题是，命名空间让我感到困惑：/。有人可以解释如何设置它以便验证吗？

我的 XML：

<?xml version="1.0" encoding="UTF-8"?>

还有我的 XSD：

Answer 1

您的架构指定 vc:minVersion="1.1"。它不使用任何 XSD 1.1 功能，因此请尝试删除此属性或将其设置为 1.0。

我能够通过使用 Saxon 运行您的验证而不启用 -xsdversion:1.1 来重现该问题。在这种情况下，您将 Saxon 作为 1.0 处理器运行，而 1.0 处理器（如果它完全识别 vc:minVersion）将跳过需要 1.1 的部分模式。

因此，另一种方法是使用 -xsdversion:1.1 运行 Saxon。

验证仍然失败，出现：

Validation error on line 27 column 34 of test.xml:
  FORG0001: In content of element <tvGuide>: The content model does not allow element
  <Provider> to appear immediately after element <ChannelDetails>. Expected <ChannelDetails>
  or nothing. 

但这是一个合理的错误：如果您希望序列（Provider、ListingDetails、ChannelDetails）是可重复的，那么您的第一个 xs:sequence 元素应该被赋予一个 maxOccurs="unbounded" 属性。
