XmlRole - how to get values from query AND from parent element

[uruselfei]

hi,

I have an XML like this:
@<services>
<service id="1">
<option id="1" value="1"/>
<option id="2" value="2"/>
</service>
<service id="2">
<option id="1" value="1"/>
<option id="2" value="2"/>
</service>
</services>@

I need to get list with options values AND with service IDs, like (service, option id, value):
1, 1, 1
1, 2, 2
2, 1, 1
2, 2, 2

I was trying to set query to "/services/service/option". this gives all options, but i can't get service ID from parent element.
XmlRole { name: "serviceId"; query: "../@id/string()" } -- gives empty result. also tried several other XPath tricks, still nothing.

unfortunately, i can't change XML, so, it is needed to solve this issue with other possibilities (preferably with standard QML)

thanks in advance

I think the query should only “/services/service" with

@XmlRole { name: “service”; query: “@id/string()” }
XmlRole { name: “option”; query: “@id[1]/string()” }
XmlRole { name: “option”; query: “@value[1]/string()” }@

yep, this would work if i need only one service. but i need them all..

currently i made workaround (not sure if they are correct from rules point of view, but anyway they work for me)

1. i get only "/services/service" and pass model to ListView. in ListView delegate i have another model with
   @
   property string serviceId
   query: "/services/service[@id=" + serviceId + "]/options"
   @
   this is like "loop-in-loop"
