我有两个csv文件：
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
我需要根据匹配的描述将来自rules.csv的类别和主题附加到records.csv文件中。
当我运行以下代码时，它可以工作，但会将rules.csv中的整行附加到一个字段中。我需要将它附加到单独的列中。
$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}"
有什么办法吗？
