## 2.5 `(...)` 特征标群
## 2.5 `(...)` 捕获组

特征标群是一组写在 `(...)` 中的子模式. 例如之前说的 `{}` 是用来表示前面一个字符出现指定次数. 但如果在 `{}` 前加入特征标群则表示整个标群内的字符重复 N 次. 例如, 表达式 `(ab)*` 匹配连续出现 0 或更多个 `ab`.

我们还可以在 `()` 中用或字符 `|` 表示或. 例如, `(c|g|p)ar` 匹配 `car` 或 `gar` 或 `par`.

前置约束和后置约束都属于**非捕获组**(用于匹配不在匹配列表中的格式).
前置约束用于判断所匹配的格式是否在另一个确定的格式之后.

例如, 我们想要获得所有跟在 `$` 符号后的数字, 我们可以使用正向向后约束 `(?<=\$)[0-9\.]*`.
