I am using Preprocessor to change content of a specific tag. The implementation looks like follows,

I will listen for openTag event and when current tag is style, I handle it in a boolean and in the text() callback, I am checking whether current tag is style.

The problem, is in a multi-threaded environment, when openTag set current tag as style and before text() resets the boolean anything called text() is considered as style tag.

I moved the boolean below asnew HtmlStreamEventReceiverWrapper(eventReceiver) { boolean isCurrentTagStyle = false; }and it seems to be working fine. Any better suggestions to handle this without a preprocessor or is there a threadsafe event processor i can use?

(new HtmlStreamEventProcessor() {	boolean isCurrentTagStyle = false; @Override	public HtmlStreamEventReceiver wrap(HtmlStreamEventReceiver eventReceiver) {	return new HtmlStreamEventReceiverWrapper(eventReceiver) {	@Override	public void openTag(String elementName, List<String> attrs) {	if (STYLE.equals(elementName))	isCurrentTagStyle = true;	super.openTag(elementName, attrs);	}	@Override	public void text(String text) {	String textContent = new String(text);	if (isCurrentTagStyle) {	try {	//Change style content here	} catch (Exception e) {	textContent = "";	} isCurrentTagStyle = false;	}	super.text(textContent);	}	};	}	});
