Find div with class using PHP Simple HTML DOM Parser

Question

I am just starting with the parser mentioned and somehow working on the problems directly from the very beginning.

Referring to this tutorial:

http://net.tutsplus.com/tutorials/php/html-parsing-and-screen-scraping-with-the-simple-html-dom-library/

I want now just to find in the source code the contents of a div with the ClearBoth Box class

I extract the code using curl and create a simple html dom object:

$cl = curl_exec($curl); $html = new simple_html_dom(); $html->load($cl); 

Then I wanted to add the contents of the div to an array called divs:

 $divs = $html->find('div[.ClearBoth Box]'); 

But now, when I print $ div, it gives much more, despite the fact that inside the div there is no more source code.

Like this:

 Array ( [0] => simple_html_dom_node Object ( [nodetype] => 1 [tag] => br [attr] => Array ( [class] => ClearBoth ) [children] => Array ( ) [nodes] => Array ( ) [parent] => simple_html_dom_node Object ( [nodetype] => 1 [tag] => div [attr] => Array ( [class] => SocialMedia ) [children] => Array ( [0] => simple_html_dom_node Object ( [nodetype] => 1 [tag] => iframe [attr] => Array ( [id] => ShowFacebookButtons [class] => SocialWeb FloatLeft [src] => http://www.facebook.com/plugins/xxx [style] => border:none; overflow:hidden; width: 250px; height: 70px; ) [children] => Array ( ) [nodes] => Array ( ) 

I do not understand why $ divs has more than just code from a div?

Here is an example of the source code on the site:

 <div class="ClearBoth Box"> <div> <i class="Icon SmallIcon ProductRatingEnabledIconSmall" title="gute peppige Qualität: Sehr empfehlenswert"></i> <i class="Icon SmallIcon ProductRatingEnabledIconSmall" title="gute peppige Qualität: Sehr empfehlenswert"></i> <i class="Icon SmallIcon ProductRatingEnabledIconSmall" title="gute peppige Qualität: Sehr empfehlenswert"></i> <i class="Icon SmallIcon ProductRatingEnabledIconSmall" title="gute peppige Qualität: Sehr empfehlenswert"></i> <i class="Icon SmallIcon ProductRatingEnabledIconSmall" title="gute peppige Qualität: Sehr empfehlenswert"></i> <strong class="AlignMiddle LeftSmallPadding">gute peppige Qualität</strong> <span class="AlignMiddle">(17.03.2013)</span> </div> <div class="BottomMargin"> gute Verarbeitung, schönes Design, </div> </div> 

What am I doing wrong?

Answer 1

The correct code for getting a div with a class:

 $ret = $html->find('div.foo'); //OR $ret = $html->find('div[class=foo]'); 

You can basically get elements since you used the CSS selector.

Answer 2

 $html = new simple_html_dom(); $html->load($output); $items = $html->find('div.youclassname',0)->children(1)->outertext; print_r($items); 

Answer 3

To find the following elements: DIV -> class(product-inner clearfix) -> class(price) you can use the following XPath:

 foreach($html->find('div[class=product-inner clearfix]') as $element){ $itemPrice = $element->find('.price',0)->plaintext; echo $itemPrice; }
