How do I parse visitors by country info from alexa?

if you search alexa with any URL's you will get a detailed traffic information of the same. what I am looking into is I would like to parse Visitors by Country info from alexa.

example for google.com

url is - http://www.alexa.com/siteinfo/google.com.

on the Audience tab you can see:

Visitors by Country for Google.com

United States 35.0%

India 8.8%

China 4.1%

Germany 3.4%

United Kingdom 3.2%

Brazil 3.2%

Iran 2.8%

Japan 2.1%

Russia 2.0%

Italy 1.9%

Brazil 3.2%

Iran 2.8%

Japan 2.1%

Russia 2.0%

Italy 1.9%

Indonesia 1.7% //etc.

How can I get only these info from alexa.com?? I have tried with preg_match function but it is very difficult in this case....

If you don't want to use DOM and getElementById which is the most elegant solution in this case, you can try regexp:

$data = file_get_contents('http://www.alexa.com/siteinfo/google.com');
preg_match_all(
   '/<a href="\/topsites\/countries\/(.*)">(.*)<\/a>/mU',
   $data,
   $result,
   PREG_SET_ORDER
);

The DOM solution looks like:

$doc = new DomDocument;

$doc->loadHTMLFile('http://www.alexa.com/siteinfo/google.com');

$data = $doc->getElementById('visitors-by-country');

$my_data = $data->getElementsByTagName('div');

$countries = array();
foreach ($my_data as $node)
{
    foreach($node->getElementsByTagName('a') as $href)
    {
        preg_match('/([0-9\.\%]+)/',$node->nodeValue, $match);
        $countries[trim($href->nodeValue)] = $match[0]; 
    }
}    

var_dump($countries);
