<?xml version="1.0" encoding="utf-8"?>
<villes>

     <ville>
          <nom>paris</nom>
          <region>ile-de-france </region>
          <departement>paris</departement>

...
<mx:httpservice id="service" url="data/villes.xml" />
...
<mx:datagrid id="grid" dataprovider="{service.lastresult.villes.ville}" />
...

 

please not event must display region not on datagrid.

hi,

it's easier work xml data. can save xml data variable or every time call lastresult service.

for geting data want

var villes:xml = xml(service.lastresult.villes);

var regions:xmllist = villes.ville.(nom == "bordeaux").region; // regions. if regions.length()>0 data founded

 <mx:httpservice id="service" url="data/villes.xml" resultformat="e4x"/>
