XSD 架构只有一个元素出现多次,而 xs:all [英] XSD schema only one element appears multiple times while xs:all
问题描述
我有一个如下所示的架构:
I have a schema which looks like:
<xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Contacts">
<xs:complexType>
<xs:sequence>
<xs:element name="Contact" maxOccurs="unbounded">
<xs:complexType>
<xs:all>
<xs:element name="Id">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minLength value="1"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="Name">
<xs:simpleType>
<xs:restriction base="xs:token">
<xs:pattern
value="[a-z\-_]+"
/>
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="Mobile">
<xs:simpleType>
<xs:restriction base="xs:Integer">
<xs:minLength value="1"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:all>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
现在的要求是我们可以为每个联系人添加多个手机号码,即一个xml,如下所示:
Now the requirement is that we can add multiple Mobile phone numbers for each contact i.e. a xml as follows:
<?xml version="1.0" encoding="UTF-8"?>
<Contacts>
<Contact>
<Id>1</Id>
<Name>Rebecca</Name>
<Mobile>1234</Mobile>
<Mobile>4567</Mobile>
</Contact>
</Contacts>
因为 xsd 中的 Contact 元素使用 xs:all,所以不允许添加多个 Mobile 元素.有没有办法允许多个 Mobile 元素但只出现其余元素?名称 &Id 应该只在 xml 中出现一次.
Because the Contact element in xsd uses xs:all, it doesn't allow adding multiple Mobile elements. Is there a way to allow multiple Mobile elements but only single occurrence of rest of the elements? Name & Id should have one occurrence only in xml.
推荐答案
这是可能的,但您必须更改
元素的模型,尤其是关于元素的顺序.
It is possible but you have to change the model of the <Contact>
element, especially regarding the order of the elements.
如果您确定
排在最前面,然后是
,那么至少有一个
>,那么这可以是一个解决方案:
If you are sure that <Id>
comes first, followed by <Name>
, then at least one <Mobile>
, then this can be a solution:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="qualified">
<xs:element name="Contacts">
<xs:complexType>
<xs:sequence>
<xs:element name="Contact" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="Id">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minInclusive value="1"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="Name">
<xs:simpleType>
<xs:restriction base="xs:token">
<xs:pattern value="[A-Za-z\-_]+"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="Mobile" maxOccurs="unbounded">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:minInclusive value="1"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
此外,
不允许作为 xs:integer
的限制方面.我以为你的意思是
.
Also, the <xs:minLength>
is not allowed as a restriction facet for xs:integer
. I assumed you meant <xs:minInclusive>
.
