How do you nest complexType elements in an xsd?
提问by Ian Campbell
I have an xml and xsd file that both validate correctly (tested at http://xsdvalidation.utilities-online.info/).
However, the xml does not validate against the xsd. I think this is because I am incorrectly nesting complexType elements in the xsd, as compared to the xml. The outer element of peopleseems to be causing the problem...
Here is the xml:
我有一个 xml 和 xsd 文件，它们都正确验证（在http://xsdvalidation.utilities-online.info/测试）。
但是，xml 不会针对 xsd 进行验证。我认为这是因为与 xml 相比，我在 xsd 中错误地嵌套了 complexType 元素。的外部元素people似乎导致了问题......
这是xml：
<?xml version = "1.0"?>
<people>
<person>
<firstname>Joe</firstname>
<lastname>Schmoe</lastname>
</person>
<person>
<firstname>Cletus</firstname>
<lastname>Jenkins</lastname>
</person>
</people>
...and here is the xsd:
...这是xsd：
<?xml version = "1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name = "people">
<xs:complexType>
<xs:sequence>
<xs:element name = "person">
<xs:complexType>
<xs:sequence>
<xs:element name = "firstname" type = "xs:string" />
<xs:element name = "lastname" type = "xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Add maxoccurs="unbounded"to the element named "person". It is a sequence of one or more person elements.
添加maxoccurs="unbounded"到名为“person”的元素。它是一个或多个人物元素的序列。

Try this for your XSD:
为您的 XSD 试试这个：
<?xml version = "1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="people" type="people"/>
<xs:complexType name="people">
<xs:sequence>
<xs:element name="person" type="person" maxOccurs="unbounded" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="person">
<xs:sequence>
<xs:element name="firstname" type="xs:string" maxOccurs="1" minOccurs="1"/>
<xs:element name="lastname" type="xs:string" maxOccurs="1" minOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
