Powershell文本字符串转换为CSV

Question

I initially thought this problem more complex than it actuially is but after digging around I still cant seem to find a solution that I can re-purpose. I'm trying to use wildcards but perhaps I'm going about this the wrong way

I have a text file as below:

SQL*Plus: Release 11.2.0.1.0 Production on Wed Aug 13 14:20:22 2014

EXTERNAL ID

--------------------------------------------------------------------------------

'M1

---


12345678-1

M07


18765432-1

M14

19638527-1

M14



EXTERNAL ID

--------------------------------------------------------------------------------

'M1

---


17418529-1

M07

I would like a single CSV with 2 columns such as:

EXTERNAL ID     M01

12345678-1      M07

18765432-1      M14

19638527-1      M14

17418529-1      M07

Any insight or help is appreciated

Answer 1

Here is something that I think will do what I want. It could probably be made more efficient and smaller but I went for easy to read and comprehend instead:

$res = @()
$content = get-content SomeFile.txt | ?{($_ -ne 'EXTERNAL ID') -AND (-NOT $_.StartsWith('"-')) -AND ($_ -ne "'M1") -AND (-NOT $_.Startswith('SQL*')) -AND ($_ -ne '')}

for($count = 0; $count -lt $content.Count; $count = $count + 2){
    $id = $content[$count]
    $m = $content[$count + 1]
    $temp = New-Object PSCustomObject -Property @{'External ID' = $id;
                                                  'M01' = $m;
    }
    $res += $temp
}
$res | Export-CSV .\Som\Path\Name.csv -NoTypeInformation

Similar to EBGreen's answer, but simpler I think.

$Col2=$false
gc c:\temp\test.txt |Select -skip 6| ?{![string]::IsNullOrEmpty($_) -and $_ -notmatch "^(---|External|'M1)"} | %{
    If($Col2){
        [PSCustomObject][Ordered]@{
            'External ID'=$Col1
            "'M1"=$_}
        $Col2=$false
        }else{
            $Col1=$_
            $Col2=$true
        }
    } | Export-Csv C:\temp\New.csv -NoTypeInformation
