I am pretty new to regex and a little confused with my example :
I have titles like theses :
What I want to do is match whatever HD or (HD) that will be at the end of the title and also the "," or " " that is just before.
Typically here with my example, I want to match everything but the "Superman" and match nothing in the last 2 titles.
I am trying something like that :
[\s,HD|\(HD\))]
But it's also matching all the other "H" "D" "," and " ".
Can anyone give a small help ?
您需要在正则表达式中使用行尾标记$
,并使其他字符为可选:
/\s*,?\(?HD\)?$/
For your example, please try this pattern:
/(?<=\bSuperman)(\s*,?(?:HD|\(HD\)))/g
EXPLANATION:
(?<=\bSuperman) # positive lookbehind to assert 'Superman' is behind
\s* # match 0 or more spaces
,? # match literal , 0 or one time
(?:HD|\(HD\)) # the ending could be 'HD' or '(HD)'
If it's everything after the superman then use this positive lookbehind:
(?<=Superman).*
If it's just HD or (HD) with or without , then:
(?<=Superman)\s?,?HD|\(HD\)
