XML schema: duplicate element occurences

[John Jørgensen]

Hi

How do I express - in XSD - that an element can contain a sequenced list of elements, and one of these elements may occur (0-n times) at BOTH sequence position x AND y?

Example:
<PRIORITY sorting="900"/>
<NAMEINFO>
subtags and data
</NAMEINFO>
<EXTRA_LINE>
subtags and data
</EXTRA_LINE>
<EXTRA_LINE>
subtags and data
</EXTRA_LINE>
<ADDRINFO>
subtags and data
</ADDRINFO>
<PHONEINFO>
subtags and data
</PHONEINFO>
<EXTRA_LINE>
subtags and data
</EXTRA_LINE>

Currently, my schema looks something like:
<xs:complexType>
<xs:sequence>
<xs:element name="PRIORITY" maxOccurs="1" minOccurs="1"> blablabla </xs:element> <xs:element name="NAMEINFO" minOccurs="0"> blablabla </xs:element> <xs:element name="LOGO" minOccurs="0"> blablabla </xs:element> <xs:element name="EXTRA_LINE" maxOccurs="10" minOccurs="0"> blablabla </xs:element> <xs:element name="ADDRINFO"> blablabla </xs:element> <xs:element name="PHONEINFO"> blablabla </xs:element> <xs:element name="EXTRA_LINE" maxOccurs="10" minOccurs="0"> blablabla </xs:element> </xs:complexType> </xs:element>

Validation says: Duplicated definition for: 'EXTRA_LINE'

I know I can just rename one of my EXTRA_LINE groups or add an extra level somewhere, but I'm not too keen on that...

Any suggestions?

Regards

That's not a very helpful error message, I agree, but _if_ the blablabla that you have edited out is <xs:complexType> .. . . </xs:complexType> then there is indeed a problem. You're not allowed to have the same element with two different type definitions in the same content model. If your two EXTRA_LINE elements actually have (textually) the _same_ type definition, move it out to the top level, give it a name, and change your model above to use

<xs:element name="EXTRA_LINE" ref="[your type]" min=0 max=10/>

and you should be fine.

The "<xs:element name="EXTRA_LINE" ref="[your type]" min=0 max=10/>" was excatly what I needed...

Thanks a lot!!!
