我有一个如下的XSD文件:
<element name="finder-def" minOccurs="0" maxOccurs="unbounded">
<complexType>
<attribute name="name" type="string" use="required"></attribute>
<attribute name="description" type="string"></attribute>
<attribute name="class" type="string" use="required"></attribute>
</complexType>
</element>
<complexType name="Dimension">
<sequence>
<element name="finder" type="Finder" minOccurs="0" maxOccurs="1"/>
</sequence>
</complexType>
<complexType name="Finder">
<attribute name="name" type="String" use="required"/>
</complexType>
XML文件对应上面的XSD文件如下:
<finder-def name="circleFinder" description="Finds circle based on msisdn" class="com.onmobile.reporting.etl.processor.common.propertyplugins.CircleIdPropertyPlugin" />
<dimension name="circleId">
<finder name="circleFinder" />
</dimension>
所以,我在这里定义了一个finder-def
,即circleFinder
,然后想要引用此finder-def
到finder
元素。
问题是如何验证finder
circleFinder
finder-def
的定义是否有定义
答案 0 :(得分:2)
在架构中使用ID和IDREF类型的另一种方法。 例: 示例XML:
<?xml version="1.0" encoding="UTF-8"?>
<f:root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:f="http://test.com/finder" xsi:schemaLocation="http://test.com/finder finder.xsd">
<f:finder-def name="circleFinder" description="Finds circle based on msisdn"
class="com.onmobile.reporting.etl.processor.common.propertyplugins.CircleIdPropertyPlugin"/>
<f:dimension name="circleId">
<f:finder name="circleFinder"/>
</f:dimension>
</f:root>
XSD架构(我已将其格式化以进行验证)
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://test.com/finder"
xmlns:tns="http://test.com/finder"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xsd:element name="root">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="finder-def" type="tns:finder-def" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element name="dimension" type="tns:Dimension" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="finder-def">
<xsd:attribute name="name" type="xsd:ID" use="required"/>
<xsd:attribute name="description" type="xsd:string"/>
<xsd:attribute name="class" type="xsd:string" use="required"/>
</xsd:complexType>
<xsd:complexType name="Dimension">
<xsd:sequence>
<xsd:element name="finder" type="tns:Finder" minOccurs="0" maxOccurs="1"/>
</xsd:sequence>
<xsd:attribute name="name" type="xsd:string"/>
</xsd:complexType>
<xsd:complexType name="Finder">
<xsd:attribute name="name" type="xsd:IDREF" use="required"/>
</xsd:complexType>
</xsd:schema>
