[Interest] Extract only src attribute of an image tag into XmlRole with XPath functions

​Hi Gianluca,

depending on the full XML you can query for the description tag and than
query for the first img tag with "[1]", something like this:

         XmlListModel {

            id: model

            query: "(/path/to/description/img)[1]"

            XmlRole { name: "img"; query: "@src/string()" }



Here I defined a role for the "src" attribute as a string.
Hope that helps.
