How is the property alias feature used to select multiple nodes?
Forum topic: Submitted by tim.hallwyl on 5. February 2008 - 13:02.
The last remark of section 8.2.6:
"Multiple nodes may be selected with this <vprop:propertyAlias> feature. However, those selections may be then filtered in the rest of expression and result in one node returned."
I cannot figure out what this means... I do not see how a query within a property alias may return multiple nodes, as it should conform with the type specified in the property. Further, the query should be evaluated the same way as a query in an assignment, according to section 7.3. In assignments a query cannot return multiple values.
Could someone provide an example of how the property alias feature is used to select multiple nodes?
Thank you.
