PHP XML DOC getElementsByTagName

Question

Wenn Sie also eine XML-Datei nach mysql importieren, aber image_14 unten nicht in der XML-Datei vorhanden ist, schlägt sie fehl, aber wenn sie existiert, funktioniert sie. Ich werde dies mit mehreren XML-Dateien tun, einige können alle 14 haben und manche nicht.

<data> 
<Images> 
    <item0> 
    <ImageID>1</ImageID> 
    </item0> 
    <item1> 
    <ImageID>2</ImageID> 
    </item1> 
</data> 


<?php 
$xmlDoc = new DOMDocument(); 
$xmlDoc->load("file.xml"); 
$mysql_hostname = ""; // Example : localhost 
$mysql_user  = ""; 
$mysql_password = ""; 
$mysql_database = ""; 

$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Oops some thing went wrong"); 
mysql_select_db($mysql_database, $bd) or die("Oops some thing went wrong"); 

$xmlObject = $xmlDoc->getElementsByTagName('data'); 
$itemCount = $xmlObject->length; 

for ($i=0; $i < $itemCount; $i++){ 
    $image_1 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(0)->childNodes->item(0)->nodeValue; 
    $image_2 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(1)->childNodes->item(0)->nodeValue; 
    $image_3 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(2)->childNodes->item(0)->nodeValue; 
    $image_4 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(3)->childNodes->item(0)->nodeValue; 
    $image_5 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(4)->childNodes->item(0)->nodeValue; 
    $image_6 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(5)->childNodes->item(0)->nodeValue; 
    $image_7 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(6)->childNodes->item(0)->nodeValue; 
    $image_8 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(7)->childNodes->item(0)->nodeValue; 
    $image_9 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(8)->childNodes->item(0)->nodeValue; 
    $image_10 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(9)->childNodes->item(0)->nodeValue; 
    $image_11 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(10)->childNodes->item(0)->nodeValue; 
    $image_12 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(11)->childNodes->item(0)->nodeValue; 
    $image_13 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(12)->childNodes->item(0)->nodeValue; 
    $image_14 = $xmlObject->item($i)->getElementsByTagName('ImageID')->item(13)->childNodes->item(0)->nodeValue; 
    $sql = "INSERT INTO `$site` ( 
    image_1,

    mysql_query($sql); 
    print "Finished";

<?php 
$xmlDoc = new DOMDocument(); 
$xmlDoc->load("file.xml"); 
$mysql_hostname = ""; // Example : localhost 
$mysql_user  = ""; 
$mysql_password = ""; 
$mysql_database = ""; 

$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Oops some thing went wrong"); 
mysql_select_db($mysql_database, $bd) or die("Oops some thing went wrong"); 

$xmlObject = $xmlDoc->getElementsByTagName('data'); 
$itemCount = $xmlObject->length; 

for ($i=0; $i < $itemCount; $i++){ 
    $image = $xmlObject->item($i)->getElementsByTagName('ImageID'); 
    $total_items_in_ImageID_tag = $image->length; 
    $total_images = []; 
    for($j = 0 ; $j < $total_items_in_ImageID_tag; $j++){ 
     $total_images["image_".$j] = $image->item($j)->childNodes->item(0)->nodeValue; 
    } 
    $insert_keys_array = array_keys($total_images); 
    $insert_key_string = implode(",", $insert_keys_array); 

    $data_to_be_inserted = ""; 
    foreach ($total_images as $image_value) { 
     $data_to_be_inserted.= "'".$image_value."',"; 
    } 

    $sql_query = "INSERT INTO `$site` (". $insert_key_string.") VALUES (". rtrim($data_to_be_inserted, ",").")"; 
    /** 
    * Query excution 
    */ 
    mysql_query($sql_query); 
    print "Finished"; 
} 
?> 

Auf diese Weise .. wird es funktionieren
