所有,我有一个XML文档,我无法控制,我需要创建一个xsd来验证。 XML文档有多种事务类型,其中一些需要特定次数,有些则不需要。父元素只是< transaction>,子元素可以是< ControlTransaction>或者< RetailTransaction>。问题是我需要一个< transaction>以< ControlTransaction>存在使用< ReasonCode>值为“Register Open”的元素和值为“Register Close”的另一个元素如下:
<?xml version="1.0" encoding="UTF-8"?>
<RegisterDay xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:cp="urn:register">
<Transaction>
<SequenceNumber>1</SequenceNumber>
<ControlTransaction>
<ReasonCode>Register Open</ReasonCode>
</ControlTransaction>
</Transaction>
<Transaction>
<SequenceNumber>2</SequenceNumber>
<RetailTransaction>
...stuff..
<Total>9.99</Total>
</RetailTransaction>
</Transaction>
<Transaction>
<SequenceNumber>3</SequenceNumber>
<ControlTransaction>
<ReasonCode>Register Close</ReasonCode>
</ControlTransaction>
</Transaction>
</RegisterDay>
我最好的尝试是在我的架构中使用类型,但得到“具有相同名称和相同范围的元素必须具有相同的类型”。我不知道怎么解决这个问题。
<?xml version="1.0"?>
<xs:schema
xmlns:cp="urn:register"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
attributeFormDefault="unqualified"
elementFormDefault="qualified">

<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="1" name="Transaction" type="TransactionRegisterOpen_type"/>
<xs:element minOccurs="1" maxOccurs="unbounded" name="Transaction" type="RetailTransaction_type"/>
<xs:element minOccurs="1" maxOccurs="1" name="Transaction" type="TransactionRegisterClose_type"/>

有没有人碰到这个和/或有任何建议?我很难过。
答案 0 :(得分:0)
也许是枚举?
