Using PHP Simple DOM Parser to get image from Wordpress Post

Question

I am using the open source PHP library known as PHP Simple HTML DOM Parser to scrape the first image of a Wordpress Post. If I call the main website:

$html = file_get_html('http://iadorefood.com/');

I get a response, an object of the DOM that I can manipulate. But if I request the URL of a specific post, my object returns NULL. Here is my command:

$html = file_get_html('http://iadorefood.com/articles/tuscany-san-gimignano/');

Why does my object return NULL? Is there something wrong with the URL?

Are there limitations in the parser (for size or supported elements)? Or does the page of the post contain errors (whereas the main does not)? — kms

Try this

include('simple_html_dom.php');
$html = file_get_html('http://iadorefood.com/articles/tuscany-san-gimignano');
$element =  $html->find('div.content p img');
echo '<img src=' . $element[0]->src . ' />';

It's tested and working, notice the trailing / at the URL, I've removed it and works fine.
