foreach循环通过Powershell中的csv文件中的一行无法工作

如何解决foreach循环通过Powershell中的csv文件中的一行无法工作

我有一个脚本正在生成一些xml文件，当我在CSV中仅添加2行时，它会按预期运行，当我添加更多行时，它只是组合值而不是循环。示例的最后一行是使用12345678.xml文件保存文件，而是使用所有行中的数字对其进行命名。例 12345678 25789654 45658965 46982268.xml 它使用循环中的所有行执行此操作。 我需要帮助来遍历每一行并每行制作1个文件，而不是梳理所有行中的数据。应该循环执行4次，保存4个文件，而不是合并所有数据的1个文件。

 #Define the source CSV with the list of MAC address and Phone Numbers 
#$sourceCSV = Import-Csv "C:\users\bob\Desktop\phones.csv" 

 
$xmltemp = Get-Content C:\users\bob\Desktop\xmltemp.xml


#Pull first 13 lines of the XML Temp as variable chunk1
$chunk1 = $xmltemp | Select-Object -First 11

#Select lines 15 to 20 of the XML Temp as variable chunk2
$chunk2 = $tdcxmltemp | Select-Object -First 6 -skip 10

#Select lines 22 to 116 of the XML Temp as variable chunk3
$Chunk3 = $tdcxmltemp | Select-Object -First 95 -skip 11

#Select lines 120 to eof of the XML Temp as variable chunk4
$Chunk4 = $tdcxmltemp | Select-Object  -skip 119



#Loop to combine the data,and generate a MACaddress.xml for each MAC listed in the CSV file
Import-Csv "C:\users\bob\Desktop\phones.csv" | ForEach-Object {

    foreach ($phone in $_.PSObject.Properties.mac){

            
                $phonenum = $sourceCSV.number
                $phonemac = $sourceCSV.mac
                $update = $sourceCSV.update_server
                    

# combine the first 13 lines of the script and Append phone number on line 13,add lines 15-20 into variable "xml2"
$xml2 = $chunk1 + ("<!-- Configuration file for Line " + $phonenum + " -->") + $chunk2


#Add Update server to xml2 variable and create xml3 variable,combine with chunk 3
$xml3 = $xml2 + ('          <update_server source="STATIC">' + $updater + "</update_server>") + $Chunk3


#combine xml3 veriable with line 117 - append phone number (line_id) into variable xml4
$xml4 = $xml3 + ('              <line_id>' + $phonenumr + "</line_id>") 


#combine xml4 veriable with line 118 - append phone number (label) into variable xml5
$xml5 = $xml4 + ('              <label>' + $phonenum + "</label>")


#combine xml5 veriable with line 119 - append phone number (sip_name) into variable xml6
$xml6 = $xml5 + ('              <sip_name>' + $phonenumr + "</sip_name>")


#Combine xml6 veriable with chunk4 into variable xml7
$xml7 = $xml6 + $chunk4 


#save the xml file and name with macadress 
$xml7 | Out-File ('C:\users\bob\Desktop\'  + $phonemac  + '.xml')
}
}

CSV文件

    mac,number,update_server
12345678,444-2223,192.168.1.1
25789654,1234567,192.168.1.1
45658965,7654321,192.168.1.1
46982268,99999999,192.168.1.1

解决方法

我不确定，但是我认为不是这个...

Import-Csv "C:\users\bob\Desktop\phones.csv" | ForEach-Object {

    foreach ($phone in $_.PSObject.Properties.mac){

        $phonenum = $sourceCSV.number
        $phonemac = $sourceCSV.mac
        $update = $sourceCSV.update_server

        ...

        #save the xml file and name with macadress 
        $xml7 | Out-File ('C:\users\bob\Desktop\'  + $phonemac  + '.xml')

    }

}

...您可能只想要这个：

Import-Csv "C:\users\bob\Desktop\phones.csv" | ForEach-Object {

    $phonenum = $_.number
    $phonemac = $_.mac
    $update   = $_.update_server

    ...

    #save the xml file and name with macadress 
    $xml7 | Out-File ('C:\users\bob\Desktop\'  + $phonemac  + '.xml')

}

请注意，在您的原始示例中，$sourceCSV.mac是一个数组，其中包含csv文件中每个记录中的mac属性的值-即@(12345678,25789654,45658965,46982268) -因此，当PowerShell评估'C:\users\bob\Desktop\' + $phonemac + '.xml'时，它将获取数组并列出每个项目，并在它们之间留有空格：

$csv = @"
mac,number,update_server
12345678,444-2223,192.168.1.1
25789654,1234567,192.168.1.1
45658965,7654321,192.168.1.1
46982268,99999999,192.168.1.1
"@

$data = $csv | ConvertFrom-CSV

$phonemac = $data.mac
$phonemac
# 12345678
# 25789654
# 45658965
# 46982268

"C:\users\bob\Desktop\"  + $phonemac  + ".xml"
# C:\users\bob\Desktop\12345678 25789654 45658965 46982268.xml

有人告诉我，foreach将$ phone的数据分配给每次迭代。 将$sourceCSV.number更改为$phone.number解决了该问题。 详细信息：

 foreach ($phone in $sourceCSV){

更改

$phonenum = $sourceCSV.number
$phonemac = $sourceCSV.mac
$update = $sourceCSV.update_server

到

 $phonenum = $phone.number
 $phonemac = $phone.mac
 $update = $phone.update_serve

解决了该问题，现在可以正常工作
