如何在数据库中导入XML数据？ （PHP）

I'm trying to import XML data into our database(mariadb). I'm very new to php.

Our XML structure:

    <?xml version="1.0" encoding="UTF-8"?>
     <webexport>
       <article key="98112" status="active">
         <productattributes>
           <group1>
             <feature key="number">
               <en name="Number" value="98112"></en>
               <fr name="Nombre" value="98112"></fr>
               <ger name="Nummer" value="98112"></ger>
            </feature>             
            <feature key="description">
               <en name="Item description" value="VKK-12-8m-11"></en>
               <fr name="Désignation" value="VKK-12-8m-11"></fr>
               <ger name="Artikelbezeichnung" value="VKK-12-8m-11"></ger>
             </feature>
           </group1>
         </productattributes>
       </article>
     </webexport>

This is what I want to have in our database:

+----+---------------+-----------+------+--------------------+--------------+
| id | articleid_des | articleid | lang | description_des    | description  |
+----+---------------+-----------+------+--------------------+--------------+
|  1 | Number        |     98112 | en   | Item description   | VKK-12-8m-11 |
|  2 | Nombre        |     98112 | fr   | Désignation        | VKK-12-8m-11 |
|  3 | Nummer        |     98112 | de   | Artikelbezeichnung | VKK-12-8m-11 |
+----+---------------+-----------+------+--------------------+--------------+

This is my current function, I'm trying to get the attributes and put it in my variables ($en_des, $en_val). But after that I don't know how to get these variables correctly in our database structure.

<?php

$xml=simplexml_load_file("exported.xml");

foreach($xml->children() as $article) {
  foreach($article->children() as $productattr) {
    foreach($productattr->children() as $group) {
      foreach($group->children() as $feature) {
        foreach($feature->children() as $en) {
          $en_des=$en['name'];
          $en_val=$en['value'];
          echo $en_des;
          echo "
";
          echo $en_val;
          echo "
";
        }
      }
    }
  }
}

This is the output of my function:

Number 98112 Nombre 98112 Nummer 98112 Item description VKK-12-8m-11 Désignation VKK-12-8m-11 Artikelbezeichnung VKK-12-8m-11
