我正在嘗試爲XML創建XSD並試圖強制實施約束,但它沒有強制實施約束。我究竟做錯了什麼?XSD中的唯一元素未強制執行
這裏是XSD
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:vc="http://www.w3.org/2007/XMLSchema-versioning"
elementFormDefault="qualified"
attributeFormDefault="unqualified"
vc:minVersion="1.1"
xmlns:o="http://www.osames.org/osamesorm">
<xs:element name="DATA">
<xs:annotation>
<xs:documentation>Element that contain data</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:sequence>
<xs:element name="ACCOUNTID" type="xs:string"/>
<xs:element name="CONTACTS" type="CONTACTType"/>
</xs:sequence>
</xs:complexType>
<xs:unique name="unique-contactid">
<xs:selector xpath="o:CONTACT"/>
<xs:field xpath="@ID"/>
</xs:unique>
</xs:element>
<xs:element name="CONTACT">
<xs:annotation>
<xs:documentation>
Contact Element contain one contact configuration/data
</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:all>
<xs:element name="ID" type="xs:int"/>
<xs:element name="TITLE" type="xs:string"/>
<xs:element name="TYPE" type="xs:int"/>
<xs:element name="CONTACTSTRING" type="xs:string"/>
</xs:all>
</xs:complexType>
</xs:element>
<xs:complexType name="CONTACTType">
<xs:annotation>
<xs:documentation>Complex Contect Type</xs:documentation>
</xs:annotation>
<xs:sequence>
<xs:element ref="CONTACT" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
,這裏是一個XML,應該是無效的,因爲2個觸點有相同的ID(0)
<?xml version="1.0" encoding="UTF-8"?>
<DATA xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="Untitled4.xsd">
<ACCOUNTID>String</ACCOUNTID>
<CONTACTS>
<CONTACT>
<ID>0</ID>
<TITLE>String</TITLE>
<TYPE>0</TYPE>
<CONTACTSTRING>String</CONTACTSTRING>
</CONTACT>
<CONTACT>
<ID>0</ID>
<TITLE>String</TITLE>
<TYPE>0</TYPE>
<CONTACTSTRING>String</CONTACTSTRING>
</CONTACT>
</CONTACTS>
</DATA>
現在知道什麼我做錯了。
謝謝。完美工作 –
