Uniqueness

[gnomff]

Hi,

I'm new to creating schemas, and I would like to make an attribute unique. What I currently have looks like this:


<xs:element name="Tick" type="TickType" maxOccurs="unbo unded" minOccurs="0">
<xs:unique name="Tick">
<xs:selector xpath="Tick"/>
<xs:field xpath="@count"/>
</xs:unique>
</xs:element>

<xs:complexTy pe name="TickType" >
<xs:attribute name="count" type="xs:int"/>
</xs:complexType>

The problem is that files with multiple Ticks with the same count are not failing like they should.

Example:
<Tick count="1">

</Tick>

<Tick count="1">

</Tick>

FYI I'm using xsv.exe to do the validation

Move the unique constraint to the parent element containing the Tick elements.

Move the unique constraint to the parent element containing the Tick elements.

Tried it, no luck. I also tried variations on the xpath selector like "./Tick" and "*/Tick" with no success.

Post the rest of your schema.

<xs:attributeGr oup name="ActionTyp eAttributes">
<xs:attribute name="type" type="xs:string "/>
<xs:attribute name="name" type="xs:string "/>
<xs:attribute name="source" type="xs:int"/>
<xs:attribute name="destinati on" type="xs:int"/>
</xs:attributeGro up>

<xs:complexTy pe name="ActionTyp e">
<xs:attributeGr oup ref="ActionType Attributes"/>
</xs:complexType>

<xs:complexTy pe name="TickType" >
<xs:sequence>
<xs:element name="Action" type="ActionTyp e"/>

<xs:attribute name="count" type="xs:int"/>
</xs:complexType>


<xs:element name="somthing" >

<xs:field xpath="@count"/>
</xs:unique>
</xs:element>
</xs:sequence>
</xs:complexType>

</xs:element>

The file i'm validating looks like this

<Tick count="1">
<Action type="FileTrans fer"
name="/fs/smUmmPeasGood.j pg"
source="1"
destination="2" />
</Tick>

<Tick count="1">
<Action type="FileTrans fer"
name="/fs/smUmmPeasGood.j pg"
source="1"
destination="2" />
</Tick>

[code=xml]
<xs:element name="somthing" >
<xs:complexType >
<xs:sequence>
<xs:element name="somthinge lse" type="xs:long"/>
<xs:element name="Tick" type="TickType" maxOccurs="unbo unded" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
<xs:unique name="Tick">
<xs:selector xpath="Tick"/>
<xs:field xpath="@count"/>
</xs:unique>
</xs:element>
[/code]

[gnomff]

[code=xml]
<xs:element name="somthing" >
<xs:complexType >
<xs:sequence>
<xs:element name="somthinge lse" type="xs:long"/>
<xs:element name="Tick" type="TickType" maxOccurs="unbo unded" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
<xs:unique name="Tick">
<xs:selector xpath="Tick"/>
<xs:field xpath="@count"/>
</xs:unique>
</xs:element>
[/code]

It's still passing even when I use that code. I've tried several different validators now to see if maybe xsv didn't have unique implemented, but with no success.

Can you post your full xml? Perhaps there's something in the structure I'm missing.
