Question

我试图遍历一系列txt文件，将信息提取到基于：分隔符的数组中。

我从文本文件中获取的所有值都适合一行，除了一行。（“广告文字”值）。这将切断最终输出中第1行之后的信息。当我事先卸下滑架并中断时，没有正确输入任何字段。

如何指定希望我的数组接受“广告文字”字段的多行输入？

下面是我正在使用的代码：

$files = ls "*.txt" 
$dictionary = @{} 
[System.Collections.Generic.List[String]]$list = @() 

foreach($f in $files){$in = Get-Content $f
 $in.Split([Environment]::NewLine) | ForEach-Object { $key,$value = $_.Split(':') 
 $dictionary[$key] = $value 
 }

[void]$list.Add( $dictionary['Ad ID'] + ',' + $dictionary['Ad Text'] + ',' + $dictionary['Ad Landing Page'] + ',' + $dictionary['Ad Targeting Location'] + ',' + $dictionary['Age'] + ',' + $dictionary['Language'] + ',' + $dictionary['Placements'] + ',' + $dictionary['Interests'] + ',' + $dictionary['Behaviors'] + ',' + $dictionary['Ad Impressions'] + ',' + $dictionary['Ad Clicks'] + ',' + $dictionary['Ad Spend'] + ',' + $dictionary['Ad Creation Date'] + ','+ $dictionary['Friends'] + ',' + $dictionary['Ad End Date'] + ',' + $dictionary['Excluded Connections'] + ',' + $dictionary['Image'] + ',' + $dictionary['Ad Targeting Location']+','+$dictionary[‘File Name’] ) 
} 


$list | Out-File -FilePath '.\trial.csv' -Append

假设Ad Text:前缀行之后的其他行本身不包含:字符：

# Create sample text file t.txt
@'
Ad ID:10
Ad Text:one
two
Ad Landing Page:http://example.org
'@ > t.txt

# Split the lines into field names and values by ":" and
# build a dictionary.
$dict = [ordered] @{}
$i = 0
(Get-Content -Raw t.txt) -split '(?m)^([^\n:]+):' -ne '' | ForEach-Object {
  if ($i++ % 2 -eq 0) {
    $key = $_
  } else {
    $dict[$key] = $_
  }
}

# Output the dictionary, showing each entry as a list.
$dict | Format-List

输出如下，显示Ad Text条目包括两行：

Name  : Ad ID
Value : 10


Name  : Ad Landing Page
Value : http://example.org


Name  : Ad Text
Value : one
        two
