这是我正在使用的正则表达式似乎不匹配。任何人都可以找出原因吗？

if ($allData =~ /(\d+)\s+(\d+|[N])\s+(\[\d+\])(.+)\s+(\[\d+\])(.+)\s+(\$\.+)\s+(\-|\+\d+\.\d+%|\-\d+\.\d+%)\s+(\d+)\s+(\-\d+|\-|\+\d+)\s+(\$\.+)\s+(\$\.+)\s+(\.+)\s+(\d+)/g)
{

$current[$i] = $1;
$last[$i] = $2;
$title[$i] = $4;
$week[$i] = $7;
$cume[$i] = $12;

printf("%-4s%-4s%-35s%-10s%-10s", $current[$i], $last[$i], $title[$i], $week[$i], $cume[$i]);

if ($last[$i] ne '-'){
    $gain = $last[$i] - $current[$i];
}

if ($gain < $bigloss){
    $bigloss = $gain;
    $losstitle = $title[$i];
}

if ($gain > $biggain){
    $biggain = $gain;
    $gaintitle = $title[$i];
}

if ($last[$i] eq '-'){

    if ($current[$i] < $bigdebut){
        $bigdebut = $current[$i];
        $bigdebuttitle = $title[$i];
    }

    if ($current[$i] > $weakdebut){
        $weakdebut = $current[$i];
        $weakdebuttitle = $title[$i];
    }
}
$i++;
}

Answer 1

试试这个正则表达式：

\d\s[A-Z0-9]\s\[\d\d\][A-Z][a-z]+(\s\b\w+\b){0,}\s(\(\d+\)\s)?\[\d\d\][A-Z]+[a-z]*\s(\(\w+\)\s)?\$(\d{1,3},){2}\d{3}\s-\s?\d+[,.]\d+((%\s\d,\d{1,3}\s-\s?\$?\d{1,3}(,\d{1,3}\s)?)|\s-\s\$\d{1,3},\d{1,3}\s)\s?\$\d{1,3},\d{1,3}(,\d{1,3})*\s\$\d{1,3}(,\d{1,3})*(\.\d+)?(\s\$\d+(\.)?\d+)?\s\d
