我需要从包含某个键值的一行文本中提取几条信息。看起来这将是一个相当普遍的情况，但我无法找到很多有用的信息。目前我正在使用选择字符串来查找包含“242200”或“242201”的所有行。一旦确定了这些行，我就会尝试提取部分行并将它们放入数据表中。然后我需要对 DT 的两列求和并将结果导出为 CSV。这是我到目前为止所拥有的：

# Create a datatable to store the values in
$dataTable = New-Object System.Data.DataTable            

$dataTable.Columns.Add("Line Number")  | Out-Null
$dataTable.Columns.Add("Transaction Date")  | Out-Null
$dataTable.Columns.Add("ID")   | Out-Null
$dataTable.Columns.Add("Premium Tax State") | Out-Null            
$dataTable.Columns.Add("Amt1", [double]) | Out-Null            
$dataTable.Columns.Add("Amt2", [double]) | Out-Null            

ForEach($match in Select-String -path $SourceFile -pattern "242200", "242201") {

    # Convert the match OBJECT to a string
    $string = $match.Line

    $row = $datatable.NewRow()
    $row["Line Number"] = $match.LineNumber
    $row["Transaction Date"] = $string.substring(3,8)
    $row["ID"] = "MA4650654" #Need to find this in the string
    $row["Premium Tax State"] = $string.substring(32,34)

    # Determine the type and amount
    if ($string -match "242200") {
        $row["Amt1"] = 0 # Need to extract these amounts and sum them
        $row["Amt2"]  = 0
    }
    else {
        $row["Amt1"] = 0 
        $row["Amt2"]  = 0
    }

    $dataTable.Rows.Add($row)
}

有没有更好的方法可以通过匹配组或其他方式来做到这一点？

尝试这样的事情（更新为在 V2 上工作）：

$str = @"
T0120131107004311         116212OK      0000000300000CYCLE 11/07/2013        JERAIEROKCAR0025593WTM

"@
$str -split "`n" | 
    Select-String -Pattern '^.{3}(.{8}).*?(?:242200|242201)(\w{2}).*?(.{10}).{3}\s*$' |
    Foreach {
        $_.matches | Foreach {$_.groups[1].value} # Date
        $_.matches | Foreach {$_.groups[2].value} # State
        $_.matches | Foreach {$_.groups[3].value} # Term at end
    }

用你的文件替换我正在使用的字符串。
