我们有一个从mac用户计算机导出的大型.vcf

导出联系人的过程产生了一个.vcf文件，该文件将所有联系人集中到一个文件中。我使用notepad++将“BEGIN:”的所有实例替换为“\nBEGIN:”，这样我今晚就可以睡觉了

计划是将每个匹配到我的reg表达式的字符串放入一个数组中，然后将每个字符串输出到许多唯一命名的.vcf文件中

（我计划稍后将字符串“BEGIN:VCARD”和“END:VCARD”添加回每个文件的开头和结尾。）

这是我们正在处理的数据的剪报：

$Regex = [Regex]::new("(?<=BEGIN:VCARD)(.*?)(?=END:VCARD)")            
$Match = $Regex.Match($String)            
if($Match.Success)

    $Match.Value            
}

$String=cat C:\temp\contacts.txt
$Regex=[Regex]：：new（（？您只要求在发布的每个代码块中进行一次匹配。

使用非消耗正则表达式将输入拆分为块
使用开始：VCARD
它检查内部是否有UID，并相应地命名输出文件
所有其他名称均命名为NoUID#0000.vcf
，并带有递增计数器


编辑简化变量，仅为输出文件名提供一个计数器
## Q:\Test\2018\06\02\SO_50659915.ps1
$InFile = '.\sample.vcf'
$Delimiter = 'BEGIN:VCARD'
$Split     = "(?!^)(?=$Delimiter)"
(Get-Content $InFile -Raw) -split $Split | ForEach-Object {$I=0}{
    $I++
    $_ | Out-File -FilePath ("Whatever{0:0000}.vcf" -f $I) -Encoding UTF8
}


##Q:\Test\2018\06\02\SO_50659915.ps1

$Delimiter='BEGIN:VCARD'
#如果分隔符包含将被解释为特殊RE字符的字符
#需要手动或使用以下命令对它们进行转义
#$Escape=[regex]：：Escape（$Delimiter）
$Split=“（？！^）（？=$Delimiter）”
（获取内容$infle-Raw）-split$split | ForEach对象{$I=0}{
如果（$匹配'UID:（？[0-9a-f\-]{32}））{
