XML : Unable to store image url from xml feed (ContentItem) tag into a database

I would like some help with coding. I am unable to save image in database using the xml tag. Can someone help me in saving the image, which is in 'ContentItem' tag, (parsing from an xml feed from a different website) in the database, please? I want to save the image from URL but save it as image in the database so I can later display it on my website as a image, not URL.

This is XML code:

  <?xml version="1.0"  encoding="UTF-8"?>  <rss version="2.0">    <item>  <title>title</title>  <link>link.com</link>   <description><![CDATA[<img src=http://www.yourwebsite.com/i.php?k=d88d4e2b336966b538983783230051c7ce6a17ce width=100 height=100>   <BR>Article!!!!!<BR>]]></description>    <ContentItem Href="http://www.yourwebsite.com/i.php?k=d88d4e2b336966b538983783230051c7ce6a17ce">   <MediaType FormalName="Picture" />   <MimeType FormalName="image/jpg" />   <Property FormalName="caption" value="Nick Carter" />   </ContentItem>    

And this is my PHP code, so far (it parses and stores everything else, except for image link):

PHP code:

    <?php     $doc = new DOMDocument();     $doc->load('http://www.yourwebsite.com/index.xml');    $arrFeeds = array();    foreach ($doc->getElementsByTagName('item') as $node) {    $itemRSS = array (     'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,    'description' => $node->getElementsByTagName('description')->item(0)->nodeValue,     'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,     'ContentItem' => $node->getElementsByTagName('ContentItem')->item(0)->getAttribute('href'),      );      array_push($arrFeeds, $itemRSS);      }          $mysqli = new mysqli('localhost', '', '', '');          if (mysqli_connect_errno()) {      printf("Connect failed: %s\n", mysqli_connect_error());      exit();       }          $check=mysqli_query($mysqli,"select * from `arti` where `title`=`title`");         $checkrows=mysqli_num_rows($check);            $stmt = $mysqli->prepare("select * from `arti` where title='?'");            if($checkrows > 0){            echo "article already exists.";          }else{           if (!$check)        {         die('Error: ' . mysqli_error($mysqli));         }         }            if ($stmt = $mysqli->prepare("INSERT INTO `arti` (`title`, `description`, `link`, image) VALUES (?, ?, ?)")) {        $stmt->bind_param('ssss', $title, $description, $link, $image);}          else {die("Errormessage: ". $mysqli->error);}           foreach( $arrFeeds as $RssItem){       $title = $RssItem["title"];       $description = $RssItem["description"];       $link = $RssItem["link"];       $image = $RssItem["ContentItem"];         $stmt->execute();        }         printf (" New Record has id %d.\n", $mysqli->insert_id);         $stmt->close();       $mysqli->close();          ?>    

I would really appreciate the help. Thanks.
