xml - 从 CSV Laravel-Excel 导出到 XML

Question

我正在使用Laravel-Excel (version-3) 将数据导入/导出为各种格式。但是我在导出到 XML 时遇到了麻烦。当我导出到 xml 时发生以下错误No writer found for type Xml。我没有任何线索或资源来解决这个问题。导出为其他格式（csv、xlsx）工作正常。谁能帮我解决这个问题！谢谢你。

这是我的代码： 在控制器中：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Exports\LoanInfoExport;

class HomeController extends Controller
{
    public function storeLoanInfo(Request $request)
    {
        $path = $request->file('upload_loan_info')->getRealPath();
        $data = \Excel::toArray('', $path, null, \Maatwebsite\Excel\Excel::TSV)[0];

        $loanInfoForExport = [];
        foreach ($data as $key => $value) {
            $disbursedValue = str_replace(',', '', $value[6]);
            $outstandingValue = str_replace(',', '', $value[7]);

            if (!empty($value[1])) {
                array_push($loanInfoForExport, [
                    'disbursed_date' => $value[0],
                    'borrower' => $value[1],
                    'loan_product' => $value[2],
                    'loan_id' => $value[3],
                    'interest' => $value[4],
                    'duration' => $value[5],
                    'disbursed' => $disbursedValue,
                    'outstanding' => $outstandingValue,
                    'status' => $value[8],
                ]);
            }
        }

        return (new LoanInfoExport($loanInfoArray))->download('invoices.xml', \Maatwebsite\Excel\Excel::XML);

    }
}

然后是 LoanInfoExport.php：

<?php

namespace App\Exports;

use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\WithStrictNullComparison;

class LoanInfoExport implements FromCollection, WithHeadings, WithStrictNullComparison
{
    use Exportable;

    public function __construct($data)
    {
        $this->data = $data;
    }

    public function collection()
    {
        return collect($this->data);
    }

    public function headings(): array
    {
        return [];
    }
}

我的意图是读取 csv 文件并将其转换为 XML。因此，如果有人对此有更好的选择，您也可以提出建议。
