title: Retrieving single node value from a nodelist
body: <p>I'm having difficulty extracting a single node value from a nodelist. </p>
  
  <p>My code takes an xml file which holds several fields, some containing text, file paths and full image names with extensions. </p>
  
  <p>I run an expath query over it, looking for the node item with a certain id. It then stores the matched node item and saves it as $oldnode</p>
  
  <p>Now my problem is trying to extract a value from that $oldnode. I have tried to var_dump($oldnode) and print_r($oldnode) but it returns the following: "object(DOMElement)#8 (0) { } "</p>
  
  <p>Im guessing the $oldnode variable is an object, but how do I access it?</p>
  
  <p>I am able to echo out the whole node list by using: echo $oldnode->nodeValue;</p>
  
  <p>This displays all the nodes in the list.</p>
  
  <p>Here is the code which handles the xml file. line 6 is the line in question... </p>
  
  <pre><code> $xpathexp = "//item[@id=". $updateID ."]";
              $xpath = new DOMXpath($xml);
              $nodelist = $xpath-&gt;query($xpathexp);
              if((is_null($nodelist)) || (! is_numeric($nodelist))) {
                $oldnode = $nodelist-&gt;item(0);
                echo $oldnode-&gt;nodeValue;
                //$imgUpload = strchr($oldnode-&gt;nodeValue, ' ');
                //$imgUpload = strrchr($imgUpload, '/');
                //explode('/',$imgUpload);
  
                //$imgUpload = trim($imgUpload); 
  
  
                $newItem = new DomDocument;
                $item_node = $newItem -&gt;createElement('item');
  
                 //Create attribute on the node as well
                $item_node -&gt;setAttribute("id", $updateID);
  
                $largeImageText = $newItem-&gt;createElement('largeImgText');
                $largeImageText-&gt;appendChild( $newItem-&gt;createCDATASection($largeImgText));
                $item_node-&gt;appendChild($largeImageText);
  
                $urlANode = $newItem-&gt;createElement('urlA');
                $urlANode-&gt;appendChild( $newItem-&gt;createCDATASection($urlA));
                $item_node-&gt;appendChild($urlANode);
  
                $largeImg = $newItem-&gt;createElement('largeImg');
                $largeImg-&gt;appendChild( $newItem-&gt;createCDATASection($imgUpload));
                $item_node-&gt;appendChild($largeImg);
  
                $thumbnailTextNode = $newItem-&gt;createElement('thumbnailText');
                $thumbnailTextNode-&gt;appendChild( $newItem-&gt;createCDATASection($thumbnailText));
                $item_node-&gt;appendChild($thumbnailTextNode);
  
                $urlB = $newItem-&gt;createElement('urlB');
                $urlB-&gt;appendChild( $newItem-&gt;createCDATASection($urlA));
                $item_node-&gt;appendChild($urlB);
  
                $thumbnailImg = $newItem-&gt;createElement('thumbnailImg');
                $thumbnailImg-&gt;appendChild( $newItem-&gt;createCDATASection(basename($_FILES['thumbnailImg']['name'])));
                $item_node-&gt;appendChild($thumbnailImg);
  
                $newItem-&gt;appendChild($item_node);
  
                $newnode = $xml-&gt;importNode($newItem-&gt;documentElement, true);
  
                         // Replace
                $oldnode-&gt;parentNode-&gt;replaceChild($newnode, $oldnode);
  
                // Display
                $xml-&gt;save($xmlFileData);
                                 //header('Location: index.php?a=112&amp;amp;id=5');
