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);
}
};
}
});
