我有下面这个列表：

originalscrape,scrapeDate,userId,username,full_name,is_private,follower_count,following_count,media_count,biography,hasProfilePic,external_url,email,contact_phone_number,address_street,isbusiness,Engagement %,MostRecentPostDate,AvgLikes,AvgComments,category,businessJoinDate,businessCountry,businessAds,countryCode,cityName,isverified

我只想获取 userId，如下所示：

189389157
51807820
194962598
4182106610
8957742561

我用过^(?:[^,\r\n]*,){3}([^,\r\n]+).*但它给我“用户名”，我想要的是用户ID。

我希望有人可以帮助我找到正确的正则表达式来仅提取用户。

谢谢

利用时间优势AM/PM格式存在before每个 ID 以及 ID 都被包围"人物：

(?:AM|PM),=\"(\d+)\"
