Perl 将多维哈希转换为csv

我有一个多维散列，我正在屏幕上打印，我想把散列转换成CSV格式的数据。 我的脚本的示例输出

$VAR1 = {
          '1' => {
                   'EVENT_NAME' => '"x1"',

负责将文件遍历为哈希的代码：

my $i=0;
open my $cap1, $file or die "Could not open $file: $!";
while( my $line = <$cap1>)  {
        my @pairs;
        my $name;
        my $value;
        if($line ne ''){
                @pairs = split / = /, $line;
                $name = $pairs[0];
                chomp($name);
                $value = $pairs[1];
                chomp($value);
        }
        if($name ne '' && $name !~ /^Status_/){
                $data{$i}{$name} = $value;
        }
        if($name =~ /^RawCaptureTimeStamp/){
                $i++;
        }
}
print Dumper \%data;

my$i=0；
打开我的$cap1，$文件或死亡“无法打开$file:$！”；
while（我的$line=）{
我的@pairs；
我的$name；
我的美元价值；
如果（$ne行“”）{
@pairs=split/=/，$line；
$name=$pairs[0]；
chomp（$name）；
$value=$pairs[1]；
咀嚼（价值）；
}
如果（$name-ne''&&$name！~/^Status\）{
$data{$i}{$name}=$value；
}
如果（$name=~/^rawCaptureTimstamp/）{
$i++；
}
}
打印转储文件\%数据；

提示：每组散列中的列不是固定的。它是动态的。

但是，我在另一个数组中得到了所有可能的列名。因此，您可以假设我在一个数组文件中有所有列（事件名称、事件类型……）。使用它，我需要将现有哈希转换为CSV。

自己找到了解决方案：

foreach my $j (sort keys %data) {
        foreach (@uniqueNames) {
                if(exists($data{$j}{$_})){
                        print "$data{$j}{$_},";
                }
                else{
                        print "\"\"",;
                }
        }
        print "\n";
}

其中，@uniqueNames是一个数组，包含原始哈希表中所有可能的唯一列。

请小心引用，如果您的值包含引号，则应根据您在CSV格式中选择的引号字符正确转义。@ChatterOne
