What is the recommended way of parsing an XML feed with multiple namespaces with ActionScript 3.0?
- by dafko
I have seen the following methods to be used in several online examples, but haven't found any documentation on the recommended way of parsing an XML feed.
Method 1:
protected function xmlResponseHandler(event:ResultEvent):void
{
var atom:Namespace = new Namespace("http://www.w3.org/2005/Atom");
var microsoftData:Namespace = new Namespace("http://schemas.microsoft.com/ado/2007/08/dataservices");
var microsoftMetadata:Namespace = new Namespace("http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
var ac:ArrayCollection = new ArrayCollection();
var keyValuePairs:KeyValuePair;
var propertyList:XMLList = (event.result as XML)..atom::entry.atom::content.microsoftMetadata::properties;
for each (var properties:XML in propertyList)
{
keyValuePairs = new KeyValuePair(properties.microsoftData::FieldLocation, properties.microsoftData::Locationid);
ac.addItem(keyValuePairs);
}
cb.dataProvider = ac;
}
Method 2:
protected function xmlResponseHandler(event:ResultEvent):void
{
namespace atom = "http://www.w3.org/2005/Atom";
namespace d = "http://schemas.microsoft.com/ado/2007/08/dataservices";
namespace m = "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata";
use namespace d;
use namespace m;
use namespace atom;
var ac:ArrayCollection = new ArrayCollection();
var keyValuePairs:KeyValuePair;
var propertyList:XMLList = (event.result as XML)..entry.content.properties;
for each (var properties:XML in propertyList)
{
keyValuePairs = new KeyValuePair(properties.FieldLocation, properties.Locationid);
ac.addItem(keyValuePairs);
}
cb.dataProvider = ac;
}
Sample XML feed:
<?xml version="1.0" encoding="iso-8859-1" standalone="yes"?>
<feed xml:base="http://www.test.com/Test/my.svc/" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://www.w3.org/2005/Atom">
