Get Xpath for HTML elements from .asp web page

Question

I need to scrape this HTML page ...

http://www.asl1.liguria.it/templateProntoSoccorso.asp

.... using PHP and XPath to get the values like 2 in

(NOTE: you could see different values in that page if you try to browse it ... it doesn't matter ..,, they changing dinamically .... )

I can't get the XPath for those values using Mozilla Firebug as usually I do: any suggestions?

Thank you in advance!

UPDATE

<?php
    ini_set('display_errors', 1);

    $url = 'http://www.asl1.liguria.it/templateProntoSoccorso.asp';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_PROXY, '');
    $data = curl_exec($ch);
    curl_close($ch);

    $dom = new DOMDocument();
    @$dom->loadHTML($data);

    $xpath = new DOMXPath($dom);

    $Number = $xpath->query('/html/body/table/tbody/tr/td[2]/table[2]/tbody/tr/td[3]/table/tbody/tr[2]/td[1]/table/tbody/tr/td/div[1]/div[3]/div[2]');

    foreach( $Number as $node )
    {
      echo "Number: " .$node->nodeValue;
      echo '<br>';
      echo '<br>';
    }    
?>

I've solved ... here you are the right code

<?php
    ini_set('display_errors', 1);

    $url = 'http://www.asl1.liguria.it/templateProntoSoccorso.asp';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_PROXY, '');
    $data = curl_exec($ch);
    curl_close($ch);

    $dom = new DOMDocument();
    @$dom->loadHTML($data);

    $xpath = new DOMXPath($dom);

    $Number = $xpath->query('(//div[@class="datiOspedaleCodici"]/div[1]/text())[1]');

    foreach( $Number as $node )
    {
      echo "Number: " .$node->nodeValue;
      echo '<br>';
      echo '<br>';
    }    
?>

that print ....
