据我所知,以下XML应该对其下面的XSD进行验证,因为所有“symbolName”值都是唯一的。但是,当我尝试验证它时,我收到以下错误

身份约束'xxxxxxsdfsdfsdfsdf'的字段'symbolName'在元素'symbols'范围内匹配9次

<levelSymbolCollection>
    <levelName>Simple</levelName>
    <symbols>
        <symbolName>Letter-A</symbolName>
        <symbolName>Letter-B</symbolName>
        <symbolName>Letter-C</symbolName>
        <symbolName>Letter-D</symbolName>
        <symbolName>Letter-E</symbolName>
        <symbolName>Letter-F</symbolName>
        <symbolName>Letter-I</symbolName>
        <symbolName>Letter-O</symbolName>
        <symbolName>Letter-U</symbolName>
    </symbols>
</levelSymbolCollection>

<xs:element name="levelSymbolCollection" maxOccurs="unbounded">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="levelName" type="requiredString"/>
            <xs:element name="symbols">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="symbolName" type="requiredString" maxOccurs="unbounded"/>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
    <xs:unique name="xxxxxxxxsdfsdfsdfsdf">
        <xs:selector xpath="symbols"></xs:selector>
        <xs:field xpath="symbolName"></xs:field>
    </xs:unique>
</xs:element>

将“symbolName”添加到选择器,设置字段xpath =“。”

<xs:element name="levelSymbolCollection" maxOccurs="unbounded">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="levelName" type="requiredString"/>
            <xs:element name="symbols">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="symbolName" type="requiredString" maxOccurs="unbounded"/>
                    </xs:sequence>
                </xs:complexType>
                <xs:unique name="xxxxxxxxsdfsdfsdfsdf">
                  <xs:selector xpath="symbolName"></xs:selector>
                  <xs:field xpath="."></xs:field>
                </xs:unique>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:element>

你显然对xs的含义有一些误解:唯一。您的声明表明每个symbolName必须具有唯一值,实际上,每个symbolName都具有唯一值。
