Hi Abdalhmed, AM> Hi all, AM> Thanks for explanations. And thanks Kevin. I needed to do something like AM> that and repeating the FormID key in the Field element was the only way AM> i found and i was not sure whether something like that is acceptable. In AM> fact, I need to do a little bit more than repeating keys. AM> Here is your IDs code :- AM> <IDs> AM> <Form FormID="FORM_1"> AM> <Field FieldID="FIELD_1" FormID="FORM_1"/> AM> <Field FieldID="FIELD_2" FormID="FORM_1"/> AM> </Form> AM> <Form FormID="FORM_2"> AM> <Field FieldID="FIELD_1" FormID="FORM_2"/> AM> </Form> AM> </IDs> AM> <xs:key name="..."> AM> <xs:selector xpath="Form/Field" /> AM> <xs:field xpath="@FormID" /> AM> <xs:field xpath="@FieldID" /> AM> </xs:key> AM> <IDs> AM> <Form FormID="1"> AM> <Field FieldID="1" FormID="1"/> AM> <Field FieldID="2" FormID="1"/> AM> </Form> AM> <Form FormID="2"> AM> <Field FieldID="1" FormID="2"/> AM> </Form> AM> <Form FormID="3"> AM> <Field FieldID="1" FormID="3"/> AM> <Field FieldID="2" FormID="3"/> AM> </Form> AM> <Description DescID="1"> AM> <Paragraph ParID="1" DescID="1"/> AM> <Paragraph ParID="2" DescID="1"/> AM> <Paragraph ParID="3" DescID="1"/> AM> </Description> AM> <Description DescID="2"> AM> <Paragraph ParID="1" DescID="2"/> AM> </Description> AM> </IDs> AM> <xs:key name="FormKey"> AM> <xs:selector xpath="Form/Field" /> AM> <xs:field xpath="@FormID" /> AM> <xs:field xpath="@FieldID" /> AM> </xs:key> AM> <xs:keyref name="RefToFormKey" refer="FormKey"> AM> <xs:selector xpath="Form/Description" /> AM> <xs:field xpath="@ParID" /> AM> <xs:field xpath="@DescID" /> AM> </xs:key> If you are trying to do what I think you are trying to do (make the attributes of Description/Paragraph reference those of Form/Field), then the <keyref> selector should be "Description/Paragraph" and the @DescID field should be before the @ParID field. (I am assuming order is significant here) So, try putting these on the <IDs> element: <xs:key name="FormKey"> <xs:selector xpath="Form/Field" /> <xs:field xpath="@FormID" /> <xs:field xpath="@FieldID" /> </xs:key> <xs:keyref name="RefToFormKey" refer="FormKey"> <xs:selector xpath="Description/Paragraph" /> <xs:field xpath="@DescID" /> <xs:field xpath="@ParID" /> </xs:key> -- groovy baby, Kevin mailto:xmldude@burieddreams.com ++++++++++++ Cool music - http://burieddreams.com/marshan ++++++ Attitude Webzine - http://burieddreams.com/attitude
