我尝试生成一个xml，但我得到一个错误：FatalErrorException in 6955f07d83b93bb8aa89577b116866e228e0c155.php line 1 syntax error, unexpected 'version' (T_STRING).
我不知道我在代码中做错了什么。
我的控制器功能是：

public function feed($gallery_id){
        $products = Products::select("id","title","brand","url","path")->where("gallery_id",$gallery_id)->get();

        foreach ($products as $product) {
            $product->path = url($product->path);
        }
        return response()->view('xml.gallery', compact('products'))->header('Content-Type', 'text/xml');

    }

我的刀片（xml.gallery）：

<?xml version="1.0"?>
