Hi I'm stuck with this output, please suggest what's wrong:

        $responsexml = @simplexml_load_string($result, 'SimpleXMLElement', LIBXML_NOCDATA | LIBXML_NOBLANKS);
	foreach ($responsexml as $hotelresponse)
	 {
		$hotelname = ($hotelresponse->HotelInfo->Name);
		$hoteldestination = ($hotelresponse->HotelInfo->Destination->Name);
		$hotelcategory = ($hotelresponse->HotelInfo->Category);
		$hotelimage = ($hotelresponse->HotelInfo->ImageList->Image[0]->Url);

		$returnedoutput .= $modx->getChunk('_testxmlchunk',array(
  			'hotel' => $hotelname,
  			'destination' => $hoteldestination,
  			'category' => $hotelcategory,
  			'image' => $hotelimage,
		));
          }

return $returnedoutput;

_testxmlchunk chunk template:

<li>this is [[+hotel]] is in [[+destination]] category [[+category]] pic <img src="[[+image]]"/></li>

It returns only the blank chunk template

<li>this is is in category pic <img src=""/></li>

but when I do this.. it works

$responsexml = @simplexml_load_string($result, 'SimpleXMLElement', LIBXML_NOCDATA | LIBXML_NOBLANKS);
	foreach ($responsexml as $hotelresponse)
	 {
		$hotelname = ($hotelresponse->HotelInfo->Name);
		$hoteldestination = ($hotelresponse->HotelInfo->Destination->Name);
		$hotelcategory = ($hotelresponse->HotelInfo->Category);
		$hotelimage = ($hotelresponse->HotelInfo->ImageList->Image[0]->Url);

		$returnedoutput .= $hotelname.' '.$hotelimage.' '. $hoteldestination.' '.$hotelcategory.';
         }

return $returnedoutput;

any suggestion... Did I miss something? I want to template my snippet.

I use:
MODX Revolution 2.2.10-pl (advanced)
mysql 5.5.37-35.0
PHP Version 5.4.29

I found the solution, I should set placeholder

$responsexml = @simplexml_load_string($result, 'SimpleXMLElement', LIBXML_NOCDATA | LIBXML_NOBLANKS);
foreach ($responsexml as $hotelresponse)
 {
    $hotelname = ($hotelresponse->HotelInfo->Name);
    $hoteldestination = ($hotelresponse->HotelInfo->Destination->Name);
    $hotelcategory = ($hotelresponse->HotelInfo->Category);
    $hotelimage = ($hotelresponse->HotelInfo->ImageList->Image[0]->Url);

    
    //////add this/////SET THE PLACEHOLDER START/////////////
    $modx->setPlaceholder('hotel',$hotelname);
    $modx->setPlaceholder('destination',$hoteldestination);
    $modx->setPlaceholder('category',$hotelcategory);
    $modx->setPlaceholder('image',$hotelimage);
    /////add this////SET THE PLACEHOLDER END//////////////

    $returnedoutput .= $modx->getChunk('_testxmlchunk',array(
        'hotel' => $hotelname,
        'destination' => $hoteldestination,
        'category' => $hotelcategory,
        'image' => $hotelimage,
    ));


  }
return $returnedoutput;
