I don’t know of any links off-hand. I would simply create a class with the set of properties you are interested in, then take the XML and parse it into instances of that class.
You can try to get XMLDecoder to do it, but sometimes it is more efficient just to write your own converter.

My data is coming from a .NET backend and most of it are in XML format and parsed into XMLListCollection. Would appreciate some more info on this.

Average collection size is 200 rows of XML (shown below) 10 columns in the datagrid with a unique item renderer for each. 1 Column can display 1 of 10 embedded images depending on an xml attribute. AS3-only Renderers are highly optimized. Average visible rows = 30 (simultaneously visible rows / meaning at least 300 renderers being recycled when scrolling?

Googling consensus shows that XMLListCollection is not the optimal dataprovider in this scenario and that XML in general is not the best choice if it can be avoided. Can anybody shed any light on a better way to improve scrolling performance based upon this scenario? Thanks in advance. -- Alex Harui Flex SDK Team Adobe System, Inc. http://blogs.adobe.com/aharui
