我懷疑我會回答，然後你會發表評論「我的真實數據完全不同，我該如何匹配？」。讓我們來看看。

# Here is your log line 
$logLine = 'This is a test 2016/01/23 This is test 04:05 AM this is a test Success Login at 01.33 sec' 

# Here is my regex which matches 
#   * date   * time AMPM * Success Login  time  * 
$myRegex = '.*(\d{4}/\d\d/\d\d).*(\d\d:\d\d \S\S).*Success Login at ([0-9.]+ \S+).*' 

# Here is the test and output building 
if ($logLine -match $myRegex) { 
    Write-Host "($($matches[1]) $($matches[2]) Success $($matches[3]))" 
} else { 
    Write-Host "Log doesn't match" 
}
