I have seen a similar article at
http://stackoverflow.com/questions/19281773/reading-multiple-xml-attributes-with-qml

However, it is still tricky to form the tree architecture that xml has in
the ListModel in QML. I also has a problem in interpreting my xml data. For
example:

<result>
<status>OK</status>
<total_count>40</total_count>
<count>20</count>
<businesses>
<business>
<business_id>7288959</business_id>

I want to have the “name/photo_url" and also the details of the "'deals"
(in which "deal" varies depending on the business). How can we combine them
together into a single ListModel element? This is a a little bit tricky for
me.

Thanks & best regards,
XiaoGuo
