Bandingkan-Objek multi nilai PowerShell
tolong, bisakah Anda membantu saya menemukan solusi untuk menangani file csv dengan beberapa kolom bidang
File1.csv
Teams,Category,Members
Team1,A,Smith;Johnson
Team1,C,Jones;Miller;Garcia
Team3,E,Wilson;Martinez
Team4,A,Martin;Jackson;White;Williams
File2.csv
Teams,Category,Members
Team1,A,Smith;Johnson
Team2,C,Jones;Miller;Garcia
Team3,E,Wilson;Martinez;Gonzalez;Hall
Team4,A,Martin;Jackson;Williams
Diff:
- Tambahkan Gonzalez dan Hall di tim 3
- Hapus Putih di Tim-4
$1 = Import-Csv -Path ".\File1.csv" -Delimiter ',' $2 = Import-Csv -Path ".\File2.csv" -Delimiter ','
Compare-Object $1 $2 -Property Members -PassThru
Hasil:
Teams Category Members SideIndicator
Team3 E Wilson;Martinez;Gonzalez;Hall =>
Team4 A Martin;Jackson;Williams =>
Team3 E Wilson;Martinez <=
Team4 A Martin;Jackson;White;Williams <=
apa yang diharapkan:
Teams Category Members SideIndicator
Team3 E Gonzalez and Hall =>
Team4 A White <=
Jawaban
Saya akan membandingkan objek terlebih dahulu untuk menemukan perbedaan (perhatikan bahwa saya membandingkan dua properti: Tim dan Anggota untuk menghindari entri yang hilang jika keanggotaan tim yang berbeda cocok) dan kemudian membandingkan array yang dibuat dari objek yang cocok:
$1 = Import-Csv -Path ".\File1.csv" -Delimiter ',' $2 = Import-Csv -Path ".\File2.csv" -Delimiter ','
$comparisonRes = Compare-Object $1 $2 -Property Teams,Members -PassThru foreach ($obj in $comparisonRes | Where-Object SideIndicator -eq "=>") { # $obj = ($comparisonRes | Where-Object SideIndicator -eq "=>")[0] $matchingEntry = $1 | Where-Object {$_.Teams -eq $obj.Teams} $matchingEntryMembers = $matchingEntry.Members -split ";" $currentEntryMembers = $obj.Members -split ";" $diffMembers = Compare-Object $matchingEntryMembers $currentEntryMembers
# Uncomment to log
# $diffMembers # Do something with $diffMembers here
}
Anda mungkin ingin menggunakan json daripada csv yang mendukung array dan angka. Jika tidak, tim terlihat seperti dua string yang dipisahkan titik koma.
file1.json
[
{"Teams":"Team1","Category":"A","Members":["Smith","Johnson"]},
{"Teams":"Team1","Category":"C","Members":["Jones","Miller","Garcia"]},
{"Teams":"Team3","Category":"E","Members":["Wilson","Martinez"]},
{"Teams":"Team4","Category":"A","Members":["Martin","Jackson","White","Williams"]}
]
file2.json
[
{"Teams":"Team1","Category":"A","Members":["Smith","Johnson"]},
{"Teams":"Team2","Category":"C","Members":["Jones","Miller","Garcia"]},
{"Teams":"Team3","Category":"E","Members":["Wilson","Martinez","Gonzalez","Hall"]},
{"Teams":"Team4","Category":"A","Members":["Martin","Jackson","Williams"]}
]
$1 = cat file1.json | convertfrom-json $2 = cat file2.json | convertfrom-json
Compare-Object $1 $2 -Property Members -PassThru
Teams Category Members SideIndicator
----- -------- ------- -------------
Team3 E {Wilson, Martinez, Gonzalez, Hall} =>
Team4 A {Martin, Jackson, Williams} =>
Team3 E {Wilson, Martinez} <=
Team4 A {Martin, Jackson, White, Williams} <=
Inilah jawaban yang lebih dekat. Jalankan bandingkan-objek pada anggota hanya satu baris pada satu waktu, lalu tambahkan tim dan kategori ke dalamnya.
$1 = cat file1.json | convertfrom-json $2 = cat file2.json | convertfrom-json
for($i = 0; $i -lt $1.length; $i++) {
compare-object $1[$i].members $2[$i].members |
select @{n='Teams'; e={$1[$i].teams}},
@{n='Category'; e={$1[$i].Category}},
@{n='Members'; e={$_.inputobject}},
sideindicator
}
Teams Category Members SideIndicator
----- -------- ------- -------------
Team3 E Gonzalez =>
Team3 E Hall =>
Team4 A White <=
Berikut cara lain menggunakan fungsi zip PowerShell / CLI: "Foreach" loop dengan beberapa array pada kedua daftar objek.
$1 = cat file1.json | convertfrom-json
$2 = cat file2.json | convertfrom-json function Zip($a1, $a2) { # function allows it to stream while ($a1) {
$x, $a1 = $a1 # $a1 gets the tail of the list
$y, $a2 = $a2 [tuple]::Create($x, $y) } } zip $1 $2 | % { $whole = $_ # will lose this $_ in the select
compare-object $whole.item1.members $whole.item2.members |
select @{n='Teams'; e={$whole.item1.teams}}, @{n='Category'; e={$whole.item1.Category}},
inputobject,sideindicator
}
Teams Category InputObject SideIndicator
----- -------- ----------- -------------
Team3 E Gonzalez =>
Team3 E Hall =>
Team4 A White <=
