Question

我试图获得powershell脚本的解决方案，以便将其从非结构化文本转换为csv格式，而且如果'TechnologyType'包含不同的数据但附加到相同的服务器名称，我将坚持如何重复更新服务器名称。我只发现了直接更新，但是这种非结构化的逐行读取方式有些不同。

来源：

Servername=svr343

TechnologyType=Storage
ID=100
DiskSize=3gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Storage
ID=110
DiskSize=9gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Interface
ID=200
localhostname=svr343
ipaddress=1.1.1.1

TechnologyType=Interface
ID=220
localhostname=svr343
ipaddress=2.2.2.2

Servername=svr400

TechnologyType=Storage
ID=180
DiskSize=5gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Storage
ID=190
DiskSize=15gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Interface
ID=250
localhostname=svr400
ipaddress=5.5.5.5

TechnologyType=Interface
ID=260
localhostname=svr400
ipaddress=6.6.6.6

CSV输出：

"ServerName","TechnologyType","ID","DIskSize","Drive","Type","localhostname","IPAddress"
"svr343","Storage","100","3gb","PhysicalDrive","SCSI","",""
"svr343","Storage","110","9gb","PhysicalDrive","SCSI","",""
"svr343","Interface","200","","","","svr343","1.1.1.1"
"svr343","Interface","220","","","","svr343","2.2.2.2"
"svr400","Storage","180","5gb","PhysicalDrive","SCSI","",""
"svr400","Storage","190","15gb","PhysicalDrive","SCSI","",""
"svr400","Interface","250","","","","svr343","5.5.5.5"
"svr400","Interface","260","","","","svr343","6.6.6.6"

Answer 1

这是一个可能的解决方案。

我选择不对其进行评论，因此，您需要尝试自己理解它。最后使用Export-Csv将数据导出到csv中。

$data = @"
Servername=svr343

TechnologyType=Storage
ID=100
DiskSize=3gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Storage
ID=110
DiskSize=9gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Interface
ID=200
localhostname=svr343
ipaddress=1.1.1.1

TechnologyType=Interface
ID=220
localhostname=svr343
ipaddress=2.2.2.2

Servername=svr400

TechnologyType=Storage
ID=180
DiskSize=5gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Storage
ID=190
DiskSize=15gb
Drive=PhysicalDrive
Type=SCSI

TechnologyType=Interface
ID=250
localhostname=svr400
ipaddress=5.5.5.5

TechnologyType=Interface
ID=260
localhostname=svr400
ipaddress=6.6.6.6

# Convert data
$outData = @()
$data -split 'Servername=' | foreach {

    $_ -match '([\w|\d]+)\s' | Out-Null
    $serverName = $Matches[1]

    $pattern = [Environment]::NewLine+"\s*"+[Environment]::NewLine
    $_ -split $pattern | foreach {

        try {
            $stringData = ConvertFrom-StringData -StringData $_
            $stringData.Add("ServerName", $serverName)
            $outData += $stringData
        } catch { }
    }
}

# Output data
$outData[3]

要读取和解析这样的文件，以下代码应该对您有用：

# read the textfile in as one single string
$serverInfo = Get-Content 'FULL PATH TO THE UNSTRUCTURED TEXT FILE' -Raw
$outputFile = 'FULL PATH TO THE RESULTING CSV FILE'

$result = @()
# match all 'Servername' blocks of text
$regex  = [regex]'(?s)Servername=((?!Servername=).)*'
$serverBlocks = $regex.Matches($serverInfo)
foreach ($server in $serverBlocks) {
    # get the server name from this text block. If missing, call it 'unknown'
    $serverName = if ($server -match 'Servername=(.*)') { $matches[1].Trim() } else { 'unknown' }

    # match all 'Technology' (server details) blocks of text
    $regex = [regex]'(?s)TechnologyType=((?!TechnologyType=).)*'
    $detailsBlocks = $regex.Matches($server.Value)
    foreach ($details in $detailsBlocks) {
        # create an object for output
        $data = "" | Select-Object 'ServerName','TechnologyType','ID','DiskSize','Drive','Type','LocalHostname','IPAddress'
        $data.ServerName = $serverName
        # split the Technology block into separate strings and read the name/value pairs
        $details.Value.Trim() -split '\r?\n' | ForEach-Object {
            $name, $value = $_ -split '=', 2
            $value = $value.Trim()
            switch ($name) {
                'TechnologyType' { $data.TechnologyType = $value; break }
                'ID'             { $data.ID = $value; break }
                'DiskSize'       { $data.DiskSize = $value; break }
                'Drive'          { $data.Drive = $value; break }
                'Type'           { $data.Type = $value; break }
                'localhostname'  { $data.LocalHostname = $value; break }
                'ipaddress'      { $data.IPAddress = $value; break }
            }
        }
        # add the object to the result array
        $result += $data
    }
}
# save the info as CSV
$result | Export-Csv $outputFile -NoTypeInformation

此后，输出CSV文件包含：

"ServerName","TechnologyType","ID","DiskSize","Drive","Type","LocalHostname","IPAddress"
"svr343","Storage","100","3gb","PhysicalDrive","SCSI",,
"svr343","Storage","110","9gb","PhysicalDrive","SCSI",,
"svr343","Interface","200",,,,"svr343","1.1.1.1"
"svr343","Interface","220",,,,"svr343","2.2.2.2"
"svr400","Storage","180","5gb","PhysicalDrive","SCSI",,
"svr400","Storage","190","15gb","PhysicalDrive","SCSI",,
"svr400","Interface","250",,,,"svr400","5.5.5.5"
"svr400","Interface","260",,,,"svr400Servername","6.6.6.6"
