ActionScript function to convert XML into Array

To allow the grouping and summary rows in DataGrid, I decided to convert existing report (old fashion DataGrid) to AdvancedDataGrid, which is a new feature of Flex 3. And which is turned out that raw XML I receive from backend returns an error. I needed more control of the data. As a part of the fix I wrote the conversion function which returns associated array collection based on input xml. Enjoy:

1. private function xml2array(xml:XMLDocument):ArrayCollection {  
2.     var ac:ArrayCollection = new ArrayCollection();  
3.     var xmlNodes:ArrayCollection = new ArrayCollection(xml.childNodes);  
4.     for (var i:int = 0; i < xmlNodes.length; i++) {  
5.         var thisRecord:Dictionary = new Dictionary();  
6.         var rowObj:Object = xmlNodes[i].childNodes;  
7.         for (var j:int = 0; j < rowObj.length; j++) {  
8.             var thisNodeName:String = rowObj[j].localName;  
9.             var thisNodeValue:String = ”;  
10.             if (rowObj[j].childNodes && rowObj[j].childNodes.length > 0) {  
11.                 if (rowObj[j].childNodes[0].nodeValue)  
12.                     thisNodeValue = rowObj[j].childNodes[0].nodeValue;  
13.                 else   
14.                     thisNodeValue = ”;  
15.             }  
16.             thisRecord[thisNodeName] = thisNodeValue;  
17.         }  
18.         ac.addItem(thisRecord);  
19.     }  
20.     return ac;  
21. }
