Size limit on string passed to new XML(str)

[designchemist]

Is there a size limit on strings passed to a new XML variable during construction?

I have noticed what I think is a hard limit on the size of strings passed as an argument to the constructor of a new XML variable in actionScript3. I noticed it while trying to pass a large string from javascript to a method in AS3. Everything works fine as long as the string is less than about 330,000 characters, but as soon as the string I pass gets a little bigger than that (say 360,0000 or more) I always get a js error somewhere in the ExternalInterface and a ActionScript error when the data is recieved. I am running on IE.
Here is what I am doing:
In javascript I have:

flashPlayer.generateFromXml(text);

Where text is some large string of serialized valid xml.

Then in AS3, I have
ExternalInterface.addCallback("generateFromXml", generateFromXml); (called in initialize handler)

then
public function generateFromXml(serializedXml:String):void
{
var x:XML = new XML(serializedXml);
}

Everything works fine until the string exceeds about 340,000 characters, then I get this js error at this line in adobe code:
function __flash__addCallback(instance, name) {
instance[name] = function () {
return eval(instance.CallFunction("<invoke name=\""+name+"\" returntype=\"javascript\">" + __flash__argumentsToXML(arguments,0) + "</invoke>")); //<<<<<--- line with breakpoint in js debugger
}
}
The ActionScript error I get is the following. I believe it happens on the line "var x:XML = new XML(serializedXml);"
(I think this because if I remove that line, I do not get the error.)

TypeError: Error #1090: XML parser failure: element is malformed.

hello, what is the value of serializedXml variable when the exception occurs?

Hi,
I think you may have an extra 0. We seem to have run up against a 36,000 character limit, when using external interface (Flash Player 9 AS3).
