How can I get a serialized HTML element with PHP DOMDocument?

This is my example script:

$html = <<<HTML <div class="main"> <div class="text"> Capture this text 1 </div> <div class="date"> May 2010 </div> </div> <div class="main"> <div class="text"> Capture this text 2 </div> <div class="date"> June 2010 </div> </div> HTML; $dom = new DOMDocument(); $dom->loadHTML($html); $xpath = new DOMXPath($dom); $tags = $xpath->query('//div[@class="main"]'); foreach ($tags as $tag) { print_r($tag->nodeValue."\n"); }

This will come out:

 Capture this text 1 May 2010 Capture this text 2 June 2010

But I need a conclusion:

 <div class="text"> Capture this text 2 </div> <div class="date"> June 2010 </div>

Or you can do something like this in my foreach loop:

 $text = $tag->query('//div[@class="text"]')->nodeValue; $date = $tag->query('//div[@class="date"]')->nodeValue;

Well, nodeValue will give you the value of node. You want what is usually called outerHTML

 echo $dom->saveXml($tag);

will output what you are looking for in X (HT) ML mode.

Starting with PHP 5.3.6, you can also pass node to saveHtml , which was previously not possible:

 echo $dom->saveHtml($tag);

The latter will obey HTML4 syntax. Thanks Artefacto for this.

try

 $dom = new DOMDocument(); $dom->loadHTML($html); $xpath = new DOMXPath($dom); $tags = $xpath->query('//div[@class="main"]'); foreach ($tags as $tag) { $innerHTML = ''; $children = $tag->childNodes; foreach ($children as $child) { $tmp_doc = new DOMDocument(); $tmp_doc->appendChild($tmp_doc->importNode($child,true)); $innerHTML .= $tmp_doc->saveHTML(); } var_dump(trim($innerHTML)); }
