如何根据起始行将一段文本分割成多行记录？

Question

如何将其拆分为单独的字符串/数组/等，以便我可以分别迭代每个字符串？目标是将它们分开，以便我可以解析每个记录并将其插入到 PSCustomObject 中。

我有以下代表超过 1 次扫描的文本块。每个扫描记录都以“根扫描路径”行开始，以“可疑文件”行结束。

我能得到的最接近的是以下行，它可以工作，但随后我丢失了“根扫描路径”行，因为它是分隔符。

$String -Split "Root Scan Path: C:\\"

扫描记录也可能超过 2 条。

Root Scan Path: C:\

Answer 1

我会在换行符上进行拆分，并将第一次出现的冒号替换为唯一字符（例如等号），然后使用

ConvertFrom-String

来获取正确的 PowerShell 对象。

'@ -split "\r?\n" |
    ForEach-Object {
        $_ -replace ':(?=\s|$)',' ='
    } | ConvertFrom-StringData -Delimiter '='

输出如下所示：
