    <p>I'm the function below, I'm struggling to output the DOMDocument without it appending the XML, HTML, <em>body</em> and <em>p</em> tag wrappers before the output of the content. The suggested fix:</p> <pre><code>$postarray['post_content'] = $d-&gt;saveXML($d-&gt;getElementsByTagName('p')-&gt;item(0)); </code></pre> <p>Only works when the content has no block level elements inside it. However, when it does, as in the example below with the h1 element, the resulting output from saveXML is truncated to...</p> <blockquote> <p>&lt;p>If you like&lt;/p></p> </blockquote> <p>I've been pointed to this post as a possible workaround, but I can't understand how to implement it into this solution (see commented out attempts below).</p> <p>Any suggestions?</p> <pre><code>function rseo_decorate_keyword($postarray) { global $post; $keyword = "Jasmine Tea" $content = "If you like &lt;h1&gt;jasmine tea&lt;/h1&gt; you will really like it with Jasmine Tea flavors. This is the last ocurrence of the phrase jasmine tea within the content. If there are other instances of the keyword jasmine tea within the text what happens to jasmine tea." $d = new DOMDocument(); @$d-&gt;loadHTML($content); $x = new DOMXpath($d); $count = $x-&gt;evaluate("count(//text()[contains(translate(., 'ABCDEFGHJIKLMNOPQRSTUVWXYZ', 'abcdefghjiklmnopqrstuvwxyz'), '$keyword') and (ancestor::b or ancestor::strong)])"); if ($count &gt; 0) return $postarray; $nodes = $x-&gt;query("//text()[contains(translate(., 'ABCDEFGHJIKLMNOPQRSTUVWXYZ', 'abcdefghjiklmnopqrstuvwxyz'), '$keyword') and not(ancestor::h1) and not(ancestor::h2) and not(ancestor::h3) and not(ancestor::h4) and not(ancestor::h5) and not(ancestor::h6) and not(ancestor::b) and not(ancestor::strong)]"); if ($nodes &amp;&amp; $nodes-&gt;length) { $node = $nodes-&gt;item(0); // Split just before the keyword $keynode = $node-&gt;splitText(strpos($node-&gt;textContent, $keyword)); // Split after the keyword $node-&gt;nextSibling-&gt;splitText(strlen($keyword)); // Replace keyword with &lt;b&gt;keyword&lt;/b&gt; $replacement = $d-&gt;createElement('strong', $keynode-&gt;textContent); $keynode-&gt;parentNode-&gt;replaceChild($replacement, $keynode); } $postarray['post_content'] = $d-&gt;saveXML($d-&gt;getElementsByTagName('p')-&gt;item(0)); // $postarray['post_content'] = $d-&gt;saveXML($d-&gt;getElementsByTagName('body')-&gt;item(1)); // $postarray['post_content'] = $d-&gt;saveXML($d-&gt;getElementsByTagName('body')-&gt;childNodes); return $postarray; } </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.
