However, there's one drawback: Since everything goes through a style sheet, you never see what XI generates.

然而，有一个缺点：由于每件事情都要通过样式表，所以您决不会看到xi生成什么。

youdao

In the first versions of XI, you would specify the regex through a pattern attribute associated to the match element.

在XI的第一个版本中，您应该通过与匹配元素相关的模式属性指定正则表达式。

youdao

If you have a sample with n observations, it's the summation I = 1 to n of xi/n--that's the average.
