PowerShell foreach 循环，所有迭代的日期相同

Question

我正在尝试通过目录解析 .txt 文件（这部分没问题）。 这些文件是报告并包含序列号列表，我也成功检索到好的列表。 每个文件包含许多序列号和一个日期，我想构建一个数组，其中第一列是序列号，第二列是重复日期，这就是我失败的地方。 如何为所有连续剧重复此日期并将其排列在 CSV 文件中？

要解析的文件示例：文件名：[Calibrage - Vérification][Sonde T Cryo][17-01-2019 14h51mn24].txt

Début de <<Calibrage / Vérification>>,  <<Sonde T Cryo>> Le 17-01-2019  14h51mn24

我想得到的是： 第一行的日期 并且只有“Les appareils ci-dessous sont Calibrés Et Vérifiés.”和“Les appareils ci-dessous n'ont pas passés le test de calibrage”之间的连续剧。

        $data = 'C:\Users\user\Desktop\DEV\2019\2019_01 Janvier\*.txt'

$regex = ($replace | % {[regex]::Escape($_)}) -join '|'
Get-ChildItem $data -recurse |
  Where-Object { $_.Name -match $RegEx} |
    Rename-Item -NewName {$_.Name -replace $RegEx, '_'}

(Get-ChildItem $data -recurse).FullName |
  Foreach-Object {
   (Get-Content $_ -Raw).
        Replace('** Les appareils ci-dessous sont Calibrés Et Vérifiés.                      **','§').
        Replace("Le seuil de tolerance est:+/-0,2°C",' ').

        $date = [regex]::matches($File,'\d{2}-\d{2}-\d{4}').value

         }
        $serial_temp = $FileContent -ireplace "^[^\[]*\[\s*","" -ireplace "\s*\][^\[]*\[\s*","`r`n" -ireplace "\]"

    Write-Host $Serial $date    

    }

Answer 1

现在您已经给我们提供了一个可以使用的示例，我认为这会对您有所帮助。

代码解析文件并导出一个包含四列的 CSV 文件：Serial、Date、Model，第四列显示“Sonde”是否通过了名为Status 的校准测试。
（当然你可以不考虑那个，但你可能会认为所有设备都可以正常工作..）

$folders = 'C:\Users\user\Desktop\DEV\2019\2019_01 Janvier'
$files   = Get-ChildItem -Path $folders -Filter '*.txt' -Force -Recurse 
$result  = @()

foreach ($file in $files) {
    # read the file as single string (-Raw) and split into 3 text blocks
    $content = Get-Content -Path $file.FullName -Raw

    # get the date from the file name
    $date = [regex]::Matches($file.Name,'\d{2}-\d{2}-\d{4}').Value
    if (!$date -and $content -match '\d{2}-\d{2}-\d{4}') {
        # if date from file name failed, try and get it from the content
        $date = $matches[0]
    }
    else {
        # if still not date is found, take it from the file itself
        $date = '{0:dd-MM-yyyy}' -f $file.LastWriteTime
    }

    # get the model number at the end of the 'Commentaire' line if any
    $model = if ($content -match 'Commentaire\s*:.*\s(\d+)[\r?\n]') { $matches[1] } else { '' }

    # split the content into text blocks and select the last two
    $content  = $content -split 'Les appareils ci-dessous' | Select-Object -Last 2

    $re = [regex]'\[\s*(?<serial>\w+)'
    foreach ($block in $content) {
        if ($block -match 'Calibrés Et Vérifiés') {
            $match = $re.Match($block)
            while ($match.Success) {
                $result += [PSCustomObject]@{
                    Serial = $match.Groups['serial'].Value
                    Date   = $date
                    Model  = $model
                    Status = 'Passed'
                }
                $match = $match.NextMatch()
            } 
        }
        elseif ($block -match "n'ont pas passés") {
            $match = $re.Match($block)
            while ($match.Success) {
                $result += [PSCustomObject]@{
                    Serial = $match.Groups['serial'].Value
                    Date   = $date
                    Model  = $model
                    Status = 'Failed'
                }
                $match = $match.NextMatch()
            } 
        }
    }
}

$result | Export-Csv "C:\Users\user\DEV\somefile.csv" -Append -NoTypeInformation

使用您的示例文件，生成的 CSV 文件将包含：

"Serial","Date","Model","Status"
"AE190150013","17-01-2019","12199","Passed"
"AE190150014","17-01-2019","12199","Passed"
"AE190150017","17-01-2019","12199","Passed"

"AE190150015","17-01-2019","12199","Passed"
"AE190150020","17-01-2019","12199","Passed"
"AE190150012","17-01-2019","12199","Passed"
"AE190150016","17-01-2019","12199","Passed"
"AE190150011","17-01-2019","12199","Passed"
"AE190150019","17-01-2019","12199","Passed"
"AE190150001","17-01-2019","12199","Passed"
"AE190150002","17-01-2019","12199","Passed"
