在使用PowerShell搜索了另一个名为Base的特定模式后，我试图在不同的行中找到一组特定的字符串，如Test2、Test3和Test4。为了同时生成Base、Test2、Test3和Test4行内容的报告，我编写了如下代码：然而，它并不总是得到所需的输出。文件数据如下所示

Base: some text
some line here
some line here
Test2: another text 
Test3: other text
Test4: different text
some lines here
some lines here
some lines here
Base: some text
some line here
some line here
Test2: another text 
Test3: other text
Test4: different text
some lines here
some lines here
some lines here
some lines here
.............

$data = Get-Content $file
$req_data = $data |where {$_.Contains("Base") -or $_.Contains("Test2") -or $_.Contains("Test3") -or $_.Contains("Test4")}
$bases_data = $data |where {$_.Contains("Base")}
foreach ($basedata in $bases_data)
{
   $find_alias = ($req_data |select-string "^${basedata}$" -context (0.10)).Context.PostContext
   $final_data = "" | select Base, Test2, Test3, Test4
   $temp.Base = $basedata
   $temp.Test2 = ($find_alias |select-string "Test2").Tostring()
   $temp.Test3 = ($find_alias |select-string "Test3").Tostring()
   $temp.Test4 = ($find_alias |select-string "Test4").Tostring()
   $temp
}

预期产出应为：

Base                Test2                Test3              Test4
Base line data     Test2 line data      Test3 line data     Test4 line data
......             .........            .......             ....
