XML Parsing memory leak

Hello,

I've a GWT application that's used on mobile devices either as a web-app or installed application with PhoneGap. I noticed that whenever you use XMLParser.parse("XML stuff") it will use a "significant" amount of memory and is almost never released fully. I tested this by putting a taphandler on a button that does nothing but parses a  430 line XML file. like this:

taskListButton.addTapHandler(new TapHandler() {

@Override

public void onTap(TapEvent event) {

XMLParser.parse("XML FILE as String...");

}

});

When I pressed that button 5-10 times it would increase memory usage by ~1MiB. As my application uses a lot of XML-messages it will increase memory usage continuously, it might release some after a while when the memory usage is already high. I don't know what triggers the memory release.

I tested this on Chrome Desktop and I can see on the Debugger Tools Timeline that document count increases by 1 and DOM node count by ~800 with each click of the button. With 25mins testing it did clear all of these from the DOM (at ~2min), but after that they were not cleaned. Can I somehow manually remove this from memory or trigger cleaning?
