XSD - 内容无效。
我正在尝试使用 Nokogiri Ruby 解析器读取 XSD 文件，但它抛出以下错误 Nokogiri::XML::SyntaxError (Element '{http://www.w3.org/2001/XMLSchema}element': 内容无效。预期为 (注释？, ((simpleType | complexType)?, (unique | key | keyref)*)).)：
有谁知道 xsd 出了什么问题吗？

I am trying to read an XSD file using Nokogiri Ruby parser and it throws following error
Nokogiri::XML::SyntaxError (Element '{http://www.w3.org/2001/XMLSchema}element': The content is not valid. Expected is (annotation?, ((simpleType | complexType)?, (unique | key | keyref)*)).):
Does any one know what is wrong with the xsd?

您收到此错误是因为不允许将
xsd:restriction作为xsd:element的子项。尝试将xsd:restriction添加到xsd:simpleType，然后在xsd:element中指定该类型。您可以将
xsd:simpleType直接添加到xsd:element中，但由于您使用相同的限制 3 次，因此会产生更多将其放在元素之外的 simpleType 中是有意义的。这是一个例子。我将 simpleType 命名为“stackOverflowTest”：
希望这会有所帮助。
You're getting the error because
xsd:restrictionis not allowed as a child ofxsd:element. Try adding yourxsd:restrictionto anxsd:simpleTypeand then specifying that type in yourxsd:element.You could add the
xsd:simpleTypedirectly to thexsd:element, but since you're using the same restriction 3 times, it makes more sense to put it in a simpleType outside of the elements.Here's an example. I named the simpleType "stackOverflowTest":
Hope this helps.
