求翻译：1947年11月，那时候的伊丽莎白公主（现在的伊丽莎白二世），嫁给希腊的菲利普王子(也就是后来的爱丁伯格公爵)，当时他们的婚礼就在这个大教堂举行。她是第10个在这个教堂举行婚礼的王室公主，她的父母于1923年4月26日也在这里举行的婚礼。当时由于二战刚刚结束两年，考虑到一些安全问题，婚礼现场只额外增添了很少量的座位，大约有2000位客人参加了观礼。是什么意思？

In November 1947, the then Princess Elizabeth (now Elizabeth), married to Greece's Prince Philippe (that is, later Duke of aidingboge), their wedding was held in the Cathedral. She is the 10th Princess celebrated in the Church of the Royal family, her parents wedding held here on April 26, 1923. At that time since the second world war had just ended a two-year, taking into account the number of security issues, wedding site extra adds only a small amount of seating about 2000 guests attended the ceremony.
