in your xml example you're not using the array operator to resolve a string to an object. you have a string in your xml file that matches the _sceneClass string.

you always need a string when using array notation to resolve a property using array notation. it might not look like a string (like in your example), but it is a string.

with an object you can use:

obj.var1

is the same as

obj["var1"]

but you couldn't use

obj[var1].

you could use:

var2 = "var1";
obj[var2];

so, if _contentXML is your xml object and it's a child of tl, you could use:

I had been trying to use the bracket notation, but incorrectly, and thinking it was futile. You gave me a huge help with it, thanks very much.

Also, I found I can reference the object does not have to be the child of some parent object. For instance, where _contentXml is my xml object, and _sceneClass is an ever-changing String that will be part of the xml path I want access to:
