Looks nice to me. In connection with the PREG_LENGTH_CAPTURE option floated in a previous post, this would easily let the wikimedia/remex-html package parse HTML in a streaming fashion; it would fill up a buffer array and then do an incremental parse, stopping as soon as a (hard) partial match was found, then move the prefix returned to the start of the buffer, wait for the buffer to fill more, then restart. --scott
