Body
If you wouldn't suprress your error reporting, you would have seen that you have a fatal error that breaks your script. In order to work with the item method: <pre><code>foreach ($lis as $li) { if (method_exists($li->childNodes, 'item')) { echo $li->childNodes->item(0)->nodeValue." "; // To reproduce the exact output you need this line also. // You need to display the second child (Answer) echo $li->childNodes->item(1)->nodeValue." "; } } </code></pre> The only difference it was that the first script <pre><code>foreach ($lis as $li) { echo $li->firstChild->nodeValue." "; echo $li->lastChild->nodeValue." "; //echo $li->childNodes->item(0)->nodeValue." "; } </code></pre> Only throws Notice: Trying to get property of non-object, but the scripts continues. As with method item() it throws a fatal error. (Fatal error: Call to a member function item() on a non-object). which kills your script. For more details on how you should iterate on these nodesList (foreach vs. for) read the comments from these pages <ul> <li><a href="http://www.php.net/manual/en/class.domnodelist.php" rel="nofollow">http://www.php.net/manual/en/class.domnodelist.php</a></li> <li><a href="http://www.php.net/manual/en/domnodelist.item.php" rel="nofollow">http://www.php.net/manual/en/domnodelist.item.php</a></li> </ul> And you especially have this issue because of the trailing space after the <code><li></code> tags. It loops like this: first <code><li></code> tag, then the space <code>' ' DOMText</code> element then the second <code><li></code> tag then the second <code>' ' DOMText</code> element. On the DOMText element it crashes. You could clear the spaces and it would work. <pre><code>$html_data = '<html><body><ol><li>Question 1 Answer1</li><li>Question 2 Answer2</li></ol></body></html>'; </code></pre>

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.
