Simple html dom find class

I am just starting with the mentioned Parser and somehow running on problems directly with the 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 simply find in a sourcecode tne content of a div with a class ClearBoth Box

I retrieve the code with 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 content of the div into an array called divs:

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

But now, when I print_r the $divs, it gives much more, despite the fact that the sourcecode has not more inside the div.

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 the $divs has not simply the code from the div?

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

          







              gute peppige Qualität (17.03.2013)

What am I doing wrong?

Finding elements by tag name

// Find all anchors, returns a array of element objects
$ret = $html->find('a');

// Find all anchors and images, returns an array of element objects
$ret = $html->find('a, img');

// Find (N)th anchor, returns element object or null if not found (zero based)
$ret = $html->find('a', 0);

// Find last anchor, returns element object or null if not found (zero based)
$ret = $html->find('a', -1);

Finding elements by class name or id

// Find all element which id=foo
$ret = $html->find('#foo');

// Find all element which class=foo
$ret = $html->find('.foo');

Finding elements by attribute

// Find all 
 with the id attribute
$ret = $html->find('div[id]');

// Find all 
 which attribute id=foo
$ret = $html->find('div[id=foo]');

// Find all anchors and images with the "title" attribute
$ret = $html->find('a[title], img[title]');

// Find all element has attribute id
$ret = $html->find('*[id]');

Attribute filters

Supports these operators in attribute selectors:

Finding descendants

// Find all 
 in 

$es = $html->find('ul li');

// Find Nested 
 tags
$es = $html->find('div div div');

// Find all
