If i do the processing of FOs in endBlock, i have to suppress the processing within nested blocks. Or the nested blocks will be processed twice.

Or the nested blocks will be processed twice. I think you can flush the queue each time a nested block starts and each time a block ends. The start of a new block forces a new line, so you can finish the current line, including whitespace processing. J.Pietschmann

All i do is ignoring all event handler functions until endBlock is called for a not-nested Block. Then i iterate recursively through its children an call all appropriate event handlers. For this purpose i have implemented a reference counter. Eachtime startBlock is entered the counter is incremented. Eachtime endBlock is entered the counter is decremented. So when the reference counter reachs 0, a not-nested block is finished and i can process all deferred FOs. Works quite good.
