如果在XSD文件中有条件 [英] if condition in XSD file

问题描述

是否可以对xml文件使用xsd架构，该文件以下列方式验证xml文件：



1.如果Attibute1值为XYZ那么Attibute2值应该是ABC？

如果Attibute1值是WXYZ那么Attibute2值应该是DEF？



当前xsd示例：

 <   xs：attribute     name   =   Attribute1   使用  =  required   表单  = 不合格   >  
 <   xs：simpleType  >  
 <   xs：restriction     base   =  xs：string >  
 <   xs：枚举    value   =  XYZ    /  >  
 <   xs：enumeration     value   =  WXYZ    /  >  
 <   / xs：restriction  >  
 <   / xs：simpleType  >  
 <   / xs：attribute  >  
 
 <   xs：attribute    名称  =  Attribute2   使用  =  required    form   = 不合格   >  
 <   xs：simpleType  >  
 <   xs：restriction     base   =  xs：string >  
 <   xs：enumeration    值  =  ABC    /  >  
 <   xs：enumeration     value   =  DEF    /   >  
 <   xs：enumeration     value   =  GHI     /  >  
 <   / xs：restriction  >  
 <   / xs：simpleType  >  
 <   / xs：attribute  >  

我添加了以下schematron代码：

 <   xs：element     name   =  ImageView    maxOccurs   =  unbounded    minOccurs   =  1    type   =  ImageView_Type   >  
 <   xs：annotation  >  
 <   xs：appinfo  < span class =code-keyword>>  
 <   sch：pattern     name   = 属性标题上的共现约束    xmlns：sch   =  http：//purl.oc lc.org/dsdl/schematron\">  
 <！ -    < sch：rule context =ImageView>    - > ;   
 <   sch：rule     context   =  * [@ Attribute1] >  
 <   sch：assert     test   = （@ Attribute1 ='XYZ'和@ Attribute2 ='ABC'） > ; 如果Attribute1为XYZ，那么Attribute2必须为ABC。<   / sch：断言 >  
  <   / sch：rule  >  
 <   / sch：pattern  >  
 <   / xs：appinfo  >  
 <   / xs：annotation  >  

但仍然没有执行验证，我使用MSXML4进行xml验证。

解决方案

 <   xs：element     name   =  ImageView    maxoccurs   =  unbounded    minoccurs   =  1    type   =  ImageView_Type    xmlns：xs   = ＃unknown >  
 <   xs：annotation  >  
 <   xs：appinfo  >  
 <   sch：pattern     name   = 属性标题上的共现约束    xmlns：sch  < span class =code-keyword> =  http://purl.oclc.org/dsdl/schematron >  
 <！ -    < sch：rule context =ImageView>    - >   
 <   xs：attribute    名称  =  Attribute1   使用  =  required    form   = 不合格 >  
 <   xs：simpletype  >  
 <   xs：restriction     base   =  xs：string >  
 <   xs：枚举    value   =  XYZ     /  >  
 <   xs：enumeration     value   =  WXYZ    /  >  
 <   / xs：restriction  >  
 <   / xs：simpletype  >  
 &l t;   / xs：attribute  >  
 
 <   xs：attribute     name   =  Attribute2   使用  =  required   表格  = 不合格 >  
 <   xs：simpletype  >  
 <   xs：r estriction     base   =  xs：string >  
 <   xs：enumeration     value   =  ABC    /  >  
 <   xs：enumeration     value   =  DEF    /  >  
 <   xs：enumeration     value   =  GHI    /  >  
 <   / xs：restriction  >  
 <   / xs：simpletype  >  
 <   / xs：attribute  >  
 <   sch：rule     context   =  * [@ Attribute1] >  
 <   sch：assert     test   = （@ Attribute1 ='XYZ'和@ Attribute2 ='ABC'） > 如果Attribute1为XYZ则Attribute2必须是ABC。<   / sch：assert  >  
 <   / sch：rule  >  
 <   / sch：pattern  >  
 <   / xs：appinfo  >  
 <   / xs：annotation  >  
 <   / xs：element   >  

Is it possible to use a xsd schema against an xml file that validates the xml file in the following ways:

1. if Attibute1 value is "XYZ" then Attibute2 value should be "ABC"?
if Attibute1 value is "WXYZ" then Attibute2 value should be "DEF"?

current xsd sample:

<xs:attribute name="Attribute1" use="required" form="unqualified" >
            <xs:simpleType>
                <xs:restriction base="xs:string">
                    <xs:enumeration value="XYZ" />
                    <xs:enumeration value="WXYZ" />
                </xs:restriction>
            </xs:simpleType>
        </xs:attribute>

        <xs:attribute name="Attribute2" use="required" form="unqualified" >
            <xs:simpleType>
                <xs:restriction base="xs:string">
                    <xs:enumeration value="ABC" />
                    <xs:enumeration value="DEF" />
                    <xs:enumeration value="GHI" />
                </xs:restriction>
            </xs:simpleType>
        </xs:attribute>

I added the following schematron code:

<xs:element name="ImageView" maxOccurs="unbounded" minOccurs="1" type="ImageView_Type" >
<xs:annotation>
    <xs:appinfo>
        <sch:pattern name="Co-occurrence constraint on attribute Title" xmlns:sch="http://purl.oclc.org/dsdl/schematron">
        <!--<sch:rule context="ImageView">-->
        <sch:rule context="*[@Attribute1]">
        <sch:assert test="(@Attribute1 = 'XYZ' and @Attribute2 = 'ABC')">If the Attribute1 is "XYZ" then the Attribute2 must be "ABC".</sch:assert>
        </sch:rule>
        </sch:pattern>
    </xs:appinfo>
</xs:annotation>

but still it is not performing the validation , i am using MSXML4 for xml validation.

解决方案

<xs:element name="ImageView" maxoccurs="unbounded" minoccurs="1" type="ImageView_Type" xmlns:xs="#unknown">
    <xs:annotation>
        <xs:appinfo>
            <sch:pattern name="Co-occurrence constraint on attribute Title" xmlns:sch="http://purl.oclc.org/dsdl/schematron">
                <!--<sch:rule context="ImageView">-->
                <xs:attribute name="Attribute1" use="required" form="unqualified">
                    <xs:simpletype>
                        <xs:restriction base="xs:string">
                            <xs:enumeration value="XYZ" />
                            <xs:enumeration value="WXYZ" />
                        </xs:restriction>
                    </xs:simpletype>
                </xs:attribute>
            
                <xs:attribute name="Attribute2" use="required" form="unqualified">
                    <xs:simpletype>
                        <xs:restriction base="xs:string">
                            <xs:enumeration value="ABC" />
                            <xs:enumeration value="DEF" />
                            <xs:enumeration value="GHI" />
                        </xs:restriction>
                    </xs:simpletype>
                </xs:attribute>
                <sch:rule context="*[@Attribute1]">
                    <sch:assert test="(@Attribute1 = 'XYZ' and @Attribute2 = 'ABC')">If the Attribute1 is "XYZ" then the Attribute2 must be "ABC".</sch:assert>
                </sch:rule>
            </sch:pattern>
        </xs:appinfo>
    </xs:annotation>
</xs:element>
