Answer 2

+1 A:

You could try whether the Simple HTML DOM parser is more fault tolerant.

And take note of the Terms & Conditions of the site you are scraping.

Answer 3

A:

A very basic example would be highly appreciated

To answer the regex part:

preg_match('!<title>(.*)</title>!s', '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
    <head>
<title>

            4 bedroom


        house


    to rent in Caroline Place, Bayswater, W2 through Foxtons (Property to rent)</title>
<meta name="keywords" content="Houses" />', $matches);
print_r($matches);

/* output:
Array
(
    [0] => <title>

            4 bedroom


        house


    to rent in Caroline Place, Bayswater, W2 through Foxtons (Property to rent)</title>
    [1] => 

            4 bedroom


        house


    to rent in Caroline Place, Bayswater, W2 through Foxtons (Property to rent)
)
*/

The s at the end of the regex puts the parser into something (inaptly) called single-line mode.

thank you very much for your help . I successfully made a script to extract the information that I needed but I still have some issues with the price . I have this : preg_match('!<noscript>\(.*), <\/noscript>!s', $itemPage , $matches); $text = $matches['1'];//clean title by html tags $price = strip_tags($text); echo $price;The $itemPage is the html content .
