OpenFL, how to check that file exist?

[Mandemon]

How do I check that given file does exist? Right now, I got following function:

public static function readCharacters(file:String = "")
{
   var members:Array<Character> = [];
   var root:Xml = Xml.parse(Assets.getText("init/" + file)).firstElement();
   //trace(root);
   return members;
 }

As you can see, it gets the file from where ever it's called. Now, I know there is a danger here: What if the file does not exist? I tried looking over OpenFL/NME API but I can't find the answer and last time I tried it crashed my program.

So, what is the error return for getText? Is it null or an empty string? I want to know so that if the function gets an file that does not exist, it will return null, which will be interpreted as an error. Once I get that out of the way, I can focus on parsing the interiors and making sure that the file is legit.

It should return null, and print a warning that the file was not found.

You can also use things like "Assets.id" to check for embedded assets, such as "Assets.id.exists ('init/' + file)"

The Haxe API to check if a file exists is FileSystem.exists, but if you're checking for embedded assets, then openfl.Assets should be a better way to go
