I'm having difficulty extracting a single node value from a nodelist. My code takes an xml file which holds several fields, some containing text, file paths and full image names with extensions. 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 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) { } " Im guessing the $oldnode variable is an object, but how do I access it? I am able to echo out the whole node list by using: echo $oldnode->nodeValue; This displays all the nodes in the list. Here is the code which handles the xml file. line 6 is the line in question... <pre><code> $xpathexp = "//item[@id=". $updateID ."]"; $xpath = new DOMXpath($xml); $nodelist = $xpath->query($xpathexp); if((is_null($nodelist)) || (! is_numeric($nodelist))) { $oldnode = $nodelist->item(0); echo $oldnode->nodeValue; //$imgUpload = strchr($oldnode->nodeValue, ' '); //$imgUpload = strrchr($imgUpload, '/'); //explode('/',$imgUpload); //$imgUpload = trim($imgUpload); $newItem = new DomDocument; $item_node = $newItem ->createElement('item'); //Create attribute on the node as well $item_node ->setAttribute("id", $updateID); $largeImageText = $newItem->createElement('largeImgText'); $largeImageText->appendChild( $newItem->createCDATASection($largeImgText)); $item_node->appendChild($largeImageText); $urlANode = $newItem->createElement('urlA'); $urlANode->appendChild( $newItem->createCDATASection($urlA)); $item_node->appendChild($urlANode); $largeImg = $newItem->createElement('largeImg'); $largeImg->appendChild( $newItem->createCDATASection($imgUpload)); $item_node->appendChild($largeImg); $thumbnailTextNode = $newItem->createElement('thumbnailText'); $thumbnailTextNode->appendChild( $newItem->createCDATASection($thumbnailText)); $item_node->appendChild($thumbnailTextNode); $urlB = $newItem->createElement('urlB'); $urlB->appendChild( $newItem->createCDATASection($urlA)); $item_node->appendChild($urlB); $thumbnailImg = $newItem->createElement('thumbnailImg'); $thumbnailImg->appendChild( $newItem->createCDATASection(basename($_FILES['thumbnailImg']['name']))); $item_node->appendChild($thumbnailImg); $newItem->appendChild($item_node); $newnode = $xml->importNode($newItem->documentElement, true); // Replace $oldnode->parentNode->replaceChild($newnode, $oldnode); // Display $xml->save($xmlFileData); //header('Location: index.php?a=112&amp;id=5'); </code></pre> Any help would be great. Thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
