使用Ruby regex查找两个字符串之间的所有匹配项

Question

如何在

等文本中扫描*|和|*之间的所有字符串

Today is *|date|*. Weather is *|weather_description|*.

使用Ruby "string...".scan(...)。

我想获得一系列匹配项：["date", "weather_description"]。

Answer 1

"Today is *|date|*. Weather is *|weather_description|*.".scan(/\*\|(.*?)\|\*/).flatten
# => ["date", "weather_description"]
