How Remove extra tag in xml in php

Here I generate on xml dynamically but in this i got the xml but in the last extra two tags came.

Here My xml 

<Main>
<Mainrow>
<code>xxxx</code>
<itemname>AAAAA</itemname>
<qty>5.000</qty>
</Mainrow>
</Main>/Mainrow></Main>

My loop 

$stock_txt = '<Main>';
            foreach($results as $key => $datas){
                   $stock_txt .= '<Mainrow>';
                    foreach($datas as $val=>$res){
                        $stock_txt .= '<'.$val.'>'.$res.'</'.$val.'>';
                    }
                        $stock_txt .= '</Mainrow>';
                }
           $stock_txt .= '</Main>';
           $dom->loadXML($stock_txt);
           $dom->save($myFile); // myFile -- my path to save file
           fwrite($fh, $stock_txt);

how to trim the last

/Mainrow and Main

I tried

substr($stock_txt,-22); but failed to get the XML generation

Thanks in advance

Do not create XML as text, use DOM or XMLWriter methods to create/add the nodes. You load your XML string into DOM and save it. So why not use DOM methods from the start:

$results = [
  [
    'code' => 'xxxx',
    'itemname'=> 'AAAAA',
    'qty'=> '5.000'
  ]
];

$document = new DOMDocument();
$main = $document->appendChild($document->createElement('Main'));
foreach ($results as $datas) {
  $row = $main->appendChild($document->createElement('Mainrow'));
  foreach ($datas as $name => $value) {
     $row
       ->appendChild($document->createElement($name))
       ->appendChild($document->createTextNode($value));
  }
}

$document->formatOutput = TRUE;
//$document->save($myFile);
echo $document->saveXml();

Output:

<?xml version="1.0"?>
<Main>
  <Mainrow>
    <code>xxxx</code>
    <itemname>AAAAA</itemname>
    <qty>5.000</qty>
  </Mainrow>
</Main>
