娱乐一下：

$s = @'
sss A=
 Key 1
sss Av=
 Hello 1
 World 1
Av.fff 

sss B=
 Key 2
sss Bv=
 Hello 2
 
 World 2
Bv.fff

sss C=

[regex]::Replace($s, "(?sm)(?:(?!Key).)*Key\s*(\d+)(?:(?!\w+\s*\1).)*(?<m>(?:(?!\r?\n\s*\w+v\.fff).)*)","Key `$1`r`n-`r`n`${m}`r`n---`r`n") -replace '(?s)\r?\n?\s*(---)(?:(?!\1).)*$' -replace '(?m)^ +(\w+)','$1';

或
([regex]::Matches($s,"(?is)Key(?:(?!\r?\n?\w+v\.fff).)*").Value -join "`r`n---`r`n") -replace '(?m)(?:(?!v=).)*v=','-' -replace '(?m)^ +(\w+)','$1';

或 自己弄
