正则表达式：忽略特定字符串或跳过/向前看某个括号

Question

I am using this regex to match and extract information from a log line:

^([^(]+)\(([^)]+)\):\s([\w]+)\s([^:]*):\s(.*)\s\[([^\]]+)\]$

It works as expected for

P:\Application\PativeCommon\Cws2essel.h(50): warning C26812: The enum type 'Cws2essel::eVesselSource' is unscoped. Prefer 'enum class' over 'enum' (Enum.3). [P:\PativeFunctionLib.vcxproj]

But fails due to the (x86) in the following line

C:\Program Files (x86)\Microsoft VisualStudio\2021\Community\VC\Tools\MSVC\14.28.29333\include\xmemory(702,82): warning C4244: 'initializing': conversion from 'double' to '_Objty', possible loss of data [G:\agent_work\48\s\Application\FunctionLib.vcxproj]

This is my code:

let rx = /^([^(]+)\(([^)]+)\):\s([\w]+)\s([^:]*):\s(.*)\s\[([^\]]+)\]/
let [, codeFile, codeLine, severity, ruleId, message, project] = logLine.match(rx);

What modifications do I need to parse the line with (x86) too. Is there a way to ignore this particular string or maybe look ahead and match the () closest to :

Please feel free to suggest better/more elegant solutions.

You may use this regex:

^(.+?)\((\d[\d,]*)\):\s(\w+)\s([^:]*):\s(.*)\s\[([^\]]+)\]$

Important changes are in first 2 capture groups:

• ^ : Start
• (.+?) : First capture group to match a string with 1 or more of any characters (lazy match)
• \( : Match opening (
• (\d[\d,]*) : 2nd capture group to match a string starting with a digit followed by 0 or more digit/comma characters
• \) : Match closing )
