[SOLVED] XSD aggegation of other elements
Posted: Thu Sep 16, 2004 6:14 am
Hi,
Hope this is the right forum to post XML-related questions.
Is it possible to define an XSD (XML Schema) element so that it is an aggregation of two other elements within the same Schema. For example:
So in the above example, in an instance ducument of this schema, if staff-name is jean-yves and week-commencing is 01-Jan-2005, then the aggregate key would be jean-yves~01-Jan-2005
This is required for a particular bit of Excel jiggery-pokery. Dont ask, just don't ask! The whole thing should be in Access anyway, but there you go.
Many thanks,
Jean-Yves

<xs:element name="company-name" type="xs:string"/>
<xs:element name="status" type="xs:string"/>
<xs:element name="week-commencing" type="xs:date"/>
<xs:element name="aggregate-key" type="xs:string">

<xs:documentation>value = staff-name + "~" + "week-commencing"</xs:documentation>
