Powershell的比较的CSV

1）Records.csv

Account,TransactionDate,Description,Amount 
Acct1,1/1/2015,Shopping at Kohls,($35.00) 
Acct1,1/1/2016,Shopping at Target,($25.22) 
Acct1,1/1/2016,Shopping at Target,($60.00) 
Acct2,4/5/2015,Subway,($9.12) 
Acct2,1/1/2016,Jimmy Johns,($11.00) 
Acct3,1/1/2016,Shopping at Kohls,($35.00) 
Acct1,1/1/2016,Shopping at Kohls,$35.00 
Acct1,1/1/2016,Shopping at Target,($60.00) 
Acct2,4/5/2015,Subway,($9.12) 
Acct2,1/1/2016,Jimmy Johns,($11.00) 
Acct2,1/1/2016,Jimmy Johns,($11.00) 
Acct3,1/1/2016,Shopping at Kohls,($35.00) 
Acct3,1/1/2016,Kroger,($27.00)

和2）rules.csv：

Description,Category,Topic 
Shopping at Kohls,Misc,Clothing 
Subway,Food,Restaurants 
Jimmy Johns,Food,Restaurants 
Shopping at Target,Misc,Home 
Kroger,Food,Groceries

我需要附加类别并根据匹配的描述将rules.csv中的主题转换为records.csv文件。

当我运行以下代码时，它可以工作，但将rules.csv中的整行附加到一个字段中。我需要将它追加到单独的列中。

$rules = import-csv "rules.CSV" 
import-csv "Records.csv" | % { 
    $desc=$_.Description 
    $_ | Add-Member NoteProperty "Category" ($rules | select-string -SimpleMatch $desc) -PassThru 
} | export-csv "output.csv" -notype

输出看起来像这样，但我需要拆分最后一列。

"Account","TransactionDate","Description","Amount","Category" 
"Acct1","1/1/2015","Shopping at Kohls","($35.00)","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct1","1/1/2016","Shopping at Target","($25.22)","@{Description=Shopping at Target; Category=Misc; Topic=Home}" 
"Acct1","1/1/2016","Shopping at Target","($60.00)","@{Description=Shopping at Target; Category=Misc; Topic=Home}" 
"Acct2","4/5/2015","Subway","($9.12)","@{Description=Subway; Category=Food; Topic=Restaurants}" 
"Acct2","1/1/2016","Jimmy Johns","($11.00)","@{Description=Jimmy Johns; Category=Food; Topic=Restaurants}" 
"Acct3","1/1/2016","Shopping at Kohls","($35.00)","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct1","1/1/2016","Shopping at Kohls","$35.00 ","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct1","1/1/2016","Shopping at Target","($60.00)","@{Description=Shopping at Target; Category=Misc; Topic=Home}" 
"Acct2","4/5/2015","Subway","($9.12)","@{Description=Subway; Category=Food; Topic=Restaurants}" 
"Acct2","1/1/2016","Jimmy Johns","($11.00)","@{Description=Jimmy Johns; Category=Food; Topic=Restaurants}" 
"Acct2","1/1/2016","Jimmy Johns","($11.00)","@{Description=Jimmy Johns; Category=Food; Topic=Restaurants}" 
"Acct3","1/1/2016","Shopping at Kohls","($35.00)","@{Description=Shopping at Kohls; Category=Misc; Topic=Clothing}" 
"Acct3","1/1/2016","Kroger","($27.00)","@{Description=Kroger; Category=Food; Topic=Groceries}"

有没有办法做到这一点？

您需要_“分裂的最后一列，“_ 怎么样？你希望'Category'和'Topic'也被抽出？ “描述”看起来已经完好无损并且呈现，所以您还可以提供一些您期望*输出的内容，以节省每个人的时间和任何困惑？ :) – gravity

@gravity谢谢。是的，我需要的类别和主题匹配的描述拉出。列标题可以是类别和主题。我不想在上面显示的这个数组表示法中使用它。再次感谢。 –

*编辑：如果你不想使用其他脚本，这应该也行

foreach ($record in $a) { 
    foreach ($obj in $b) { 
     if ($obj.description -eq $record.description) { 
      $record | select *, @{n='Category';e={$obj.Category}}, @{n='Topic';e={$obj.Topic}} 
     } 
    } 
}

谢谢 - 这似乎正是我所需要的。但是，我是一个新手，我甚至不知道如何导入PS文件以使这些功能可用。使用谷歌搜索，并在一小时内尝试 - 现在在Mac上，并在其他东西上工作。谢谢。 –

找到了包含.ps1文件的方法。基本上。。\ MyFunctions.ps1即将尝试。谢谢。 –

再次感谢您的帮助。倾向于较小的脚本。我试过了，除了没有匹配“规则”的“记录”之外，它效果很好。我尝试了一个“其他”的声明，但没有得到我想要的结果。基本上，如果规则csv中没有匹配的描述，我们应该得到一个空的类别和主题。希望这是有道理的。谢谢！！ –
