    <p>I am trying to develop a function that removes certain URL nodes from my sitemap file. Here is what I have so far.</p> <pre><code>$xpath = new DOMXpath($DOMfile); $elements = $xpath-&gt;query("/urlset/url/loc[contains(.,'$pageUrl')]"); echo count($elements); foreach($elements as $element){ //this is where I want to delete the URL echo $element; echo "here".$element-&gt;nodeValue; } </code></pre> <p>Which outputs "111111". I don't know why I can't echo a string in a foreach loop if the $elements count is '1'.</p> <p>Up until now, I've been doing</p> <pre><code>$urls = $dom-&gt;getElementsByTagName( "url" ); foreach( $urls as $url ){ $locs = $url-&gt;getElementsByTagName( "loc" ); $loc = $locs-&gt;item(0)-&gt;nodeValue; echo $loc; if($loc == $fullPageUrl){ $removeUrl = $dom-&gt;removeChild($url); } } </code></pre> <p>Which would work fine if my sitemap wasn't so big. It times out right now, so I'm hoping using xpath queries will be faster.</p> <p>After Gordon's comment, I tried:</p> <pre><code>$xpath = new DOMXpath($DOMfile); $query = sprintf('/urlset/url[./loc = "%d"]', $pageUrl); foreach($xpath-&gt;query($query) as $element) { //this is where I want to delete the URL echo $element; echo "here".$element-&gt;nodeValue; } </code></pre> <p>And its not returning anything.</p> <p>I tried going a step further and used codepad, using what was used in the other post mentioned, and did this:</p> <pre><code>&lt;?php error_reporting(-1); $xml = &lt;&lt;&lt; XML &lt;?xml version="1.0" encoding="UTF-8" ?&gt; &lt;url&gt; &lt;loc&gt;professional_services&lt;/loc&gt; &lt;loc&gt;5professional_services&lt;/loc&gt; &lt;loc&gt;6professional_services&lt;/loc&gt; &lt;/url&gt; XML; $id = '5professional_services'; $dom = new DOMDocument; $dom-&gt;loadXML($xml); $xpath = new DOMXPath($dom); $query = sprintf('/url/[loc = $id]'); foreach($xpath-&gt;query($query) as $record) { $record-&gt;parentNode-&gt;removeChild($record); } echo $dom-&gt;saveXml(); </code></pre> <p>and I'm getting a "Warning: DOMXPath::query(): Invalid expression" at the foreach loop line. Thanks for the other comment on the urlset, I'll be sure to include the double slashes in my code, tried it and it returned nothing.</p>

    2. CO`$url` is a `DOMNodelist` not a `DOMElement`? And the list cannot be removed, maybe you need to iterate over the list and remove each element?

    3. COI don't understand jakenoble. Do you think the code I had before that ran through the XML and compared all loc nodes to the php variable was the right way to go? Maybe I have faulty code in the way it is right now?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
