Question

Hi i am using DOM for retrieving the data from an xml file. The code below is working perfectly fine for the xml file, but the main problem i am facing is that it recognizes only the root nodes, it does not recognizes child nodes.
Here’s my code:-

 $dom = new DOMDocument();
    $dom->load($url);
    $link = $dom->getElementsByTagName($tag_name);
    $value = array();
for ($i = 0; $i < $link->length; $i++) {
            $childnode['name']=$link->item($i)->nodeName;
            $childnode['value']=$link->item($i)->nodeValue;
            $value[ $childnode['name']] = $childnode['value'];
        // echo $link->item($i)->nodeValue . '<br>';
       $k++;
    }

This is my view file where i am displaying the data

foreach($value as $node=>$value)
{
echo "<b> Node :</b>".$node."<br /><b>Value:</b>".$value."<br /><hr>";
}

This is my xml file

<name>John</name>
<place>Australia</place>
<contact> 
<phone>8734563485</phone> 
<type>Mobile</type> 
</contact>
<mail>somedata</mail>

I am able to read the parent nodes i,e name, place,contact,mail. But i am unable to read child nodes i,e phone,type.
Can anyone plz help me with the code….

Answer 1

because you are not traversing the child nodes of course.
I would create a function and traverse it recursive.

 function addNodesToValue($value,$nodelist) {
   for ($i = 0; $i < $nodelist->length; $i++) {
     $childnode['name']=$nodelist->item($i)->nodeName;
     $childnode['value']=$nodelist->item($i)->nodeValue;
     $value[ $childnode['name']] = $childnode['value'];
     // recursive traverse child nodes
     if($nodelist->item($i)->hasChildNodes()){
       $value = addNodesToValue($value,$nodelist->item($i)->childNodes);
     }
    }
    return $value;
 } 

//usage
$value = addNodesToValue($value,$link);
