XSD with "required" attribute option related query

Post by rajneesh » Fri Feb 21, 2020 12:56 pm

Hello All,

I am new to XSD and XML and need to explore if there is option to make sure that any one attribute in a set of attributes within same element is required.

Example:

<xs:element name="where" maxOccurs="1" minOccurs="0">
<xs:complexType>
<xs:sequence>
<xs:element name="condition" maxOccurs="unbounded" minOccurs="1">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute type="xs:string" name="alias1" use="required"/>
<xs:attribute type="xs:string" name="col1" use="required"/>
<xs:attribute type="xs:string" name="operator" use="required"/>
<xs:attribute type="xs:string" name="string" use="optional"/>
<xs:attribute type="xs:string" name="number" use="optional"/>
<xs:attribute type="xs:string" name="date" use="optional"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>

Here I want to ensure that minimum one attribute in a set of 3 attributes (mentioned as optional in above) are required. All can not be optional , however any one (can be more than one also) is required.

Thanks,
Rajneesh

Hi,

I'm afraid, there is no other way than to write a XML reader and obtain the list of attributes and their values from code. I would suggest to start with these posts:

Thank you, One more help please:
Is it possible to impose required constraint at value level?

for example in below xml, I wnt to make sure value for alias1, coli1 and operator is always populated in condition element within where element.


functionalView name="CLAIMS_FV" description="Learning Purpose">
<columns>
<column name="CLAI.CODE" columnAlias="CODE" description="The code of the claim" />
<column name="CLLI.CODE" columnAlias="LINE_CODE" description="The code of the claim line" />
<column name="PROC.CODE" columnAlias="PROC_CODE" description="The code of the claim line procedure" />
</columns>
<fromviews>
<fromview name="CLAIMS_V" alias="CLAI" />
<fromview name="LINES_V" alias="CLLI" />
<fromview name="PROC_V" alias="PROC" />
<fromview name="PROV_V" alias="PROV" />
<fromview name="FORMS_V" alias="CLFO"/>
<fromview name="FORMTYPES_V" alias="CFTY"/>
</fromviews>
<joins>
<join alias1="CLLI" col1="CLAI_ID" condition="=" alias2="CLAI" col2="ID"/>
<join alias1="CLFO" col1="ID" condition="=" alias2="CFTY" col2="CLFO_ID"/>
<join alias1="CFTY" col1="ID" condition="=" alias2="PROC" col2="CFTY_ID"/>
<leftouterjoin alias1="PROV" col1="ID" condition="=" alias2="CLAI" col2="PROVIDER_ID"/>
</joins>
<where>
<condition alias1="CFTY" col1="CODE" operator="=" string="" number="" date= "" />
</where>
</functionalView>
