正则表达式:在括号之间找到一个数字

Question

我需要一个正则表达式,在下面找到以粗体显示的数字:

20(LBDD你好312312)马铃薯1651(98)

20(LBDD你好312312兔子)马铃薯1651(98)

20(312312)马铃薯1651(98)

((\ d +))找到数字98

当括号中有其他字符时,我不知道该怎么办

Answer 1

这仅匹配第一个捕获组中的312312:

^.*?\([^\d]*(\d+)[^\d]*\).*$

Regexplanation:

^        # Match the start of the line
.*?      # Non-greedy match anything
\(       # Upto the first opening bracket (escaped)
[^\d]*   # Match anything not a digit (zero or more)
(\d+)    # Match a digit string (one or more)
[^\d]*   # Match anything not a digit (zero or more)
\)       # Match closing bracket
.*       # Match the rest of the line
$        # Match the end of the line

在这里看到它.
