[JS] Problem defining an object while grabbing info from xmlElements

Hi,

Here is some piece of code I wrote in order to create an object. This object is expected to contain a property whise name is based on the value of

the "airport_title" tag. I set the value to the page the xmlElement is on.

The XML STructure in Indesign is like this :

When I run this code, I can see that the properties have been defined. However, if I try to access them, it returns undefined.

obj["TXFULLSHEARTexasX09"]//undefined

More confusing is that I place a dummy "toto" property which is available.

obj["toto"] //28500 as expected.

I am out of ideas here. Any hint ?

TIA Loic

PS: I checked the my variable airport_title variableconbstructor and that's a string.

Here is the code

function makePageIndexFromAirportTemplate(aTemplate){
  //var tempDoc=app.open(aTemplate);  
  var tempDoc=app.activeDocument;
  var airportPages = {};
  try{
      var airports_catalogue = tempDoc.xmlElements[0];      
      var airport=airports_catalogue.xmlElements;
      var airportLength = airport.length;
    
    for(var i=0; i<airportLength; i++){
         var theAirport = airport;
         //alert(airport.markupTag.name);
         var bloc_airport = theAirport.xmlElements[0];
         var airportTitle = bloc_airport.contents;
         airportTitle = airportTitle.replace(/[ \-,;()]/g,"");
       
        // alert(bloc_airport.storyOffset.parentTextFrames[0].parentPage.name);
         var pg = bloc_airport.storyOffset.parentTextFrames[0].parentPage.name;
         //airportPages["\""+airportTitle+"\""]=Number(pg);
         //var airportTitle = "\""+airportTitle+"\"";
         
         airportPages[airportTitle]=pg;
      }
        //tempDoc.close();  
        airportPages["toto"]="28500";
        return airportPages;
  }
    catch(e){
       alert(e);
    }
    //tempDoc.close();   
    return false; 
}


var obj = makePageIndexFromAirportTemplate();
obj["toto"];
