Question

Hi I have the following code and I only want to pull out links that have www. in them

<p> Text < href="http://url.com/link/">link text</a> more text < href="http://www.anotehrurl.com/">more link text</a> and < href="http://www.anotherurl.com/sub/sub/link.html">link text</a>. more text < href="http://keepurl.co.uk/link/">link text</a> more text < href="http://www.anotherurl.com/sub/sub/link.html">link text</a>. < href="http://www.anotherurl.com/sub/sub/link.html">link text</a>.  < href="http://www.anotehrurl.com/">more link text</a></p>

im using the reg expression:

(<a href="http:\/\/www.[\d\D]*?\/">([\d\D]*?)<\/a>)

basically I want to match any link that starts with www and not match any link that is keepurl.co.uk/…….

I have put this through rubular and come out with following:

{
Result 1

1.< href=”http://www.anotehrurl.com/&#8221;>more link text
2.more link text
Result 2

1.< href=”http://www.anotherurl.com/sub/sub/link.html&#8221;>link text. more text
< href=”http://keepurl.co.uk/link/&#8221;>link text
2.link text
Result 3

1.< href=”http://www.anotherurl.com/sub/sub/link.html&#8221;>link text. < href=”http://www.anotherurl.com/sub/sub/link.html&#8221;>link text. < href=”http://www.anotehrurl.com/&#8221;>more link text
2.more link text
}

as u can see its pulling out more than i want.

cheers

What about this:

       <?php
        $html = <<<END
   <p> Text < href="http://url.com/link/">link text</a> more text
       < href="http://www.anotehrurl.com/">more link text</a>
       and < href="http://www.anotherurl.com/sub/sub/link.html">link text</a>.
       more text < href="http://keepurl.co.uk/link/">link text</a> more text
       < href="http://www.anotherurl.com/sub/sub/link.html">link text</a>.
       < href="http://www.anotherurl.com/sub/sub/link.html">link text</a>.
       < href="http://www.anotehrurl.com/">more link text</a></p>
END;


        $r = '#href=\"http://(www\.[^\"]*)\">(.+)</#iU';

        preg_match_all($r, $html, $m);

        var_dump($m[1]);
        var_dump($m[2]);
        ?>

OUTPUT:

array
  0 => string 'www.anotehrurl.com/' (length=19)
  1 => string 'www.anotherurl.com/sub/sub/link.html' (length=36)
  2 => string 'www.anotherurl.com/sub/sub/link.html' (length=36)
  3 => string 'www.anotherurl.com/sub/sub/link.html' (length=36)
  4 => string 'www.anotehrurl.com/' (length=19)
array
  0 => string 'more link text' (length=14)
  1 => string 'link text' (length=9)
  2 => string 'link text' (length=9)
  3 => string 'link text' (length=9)
  4 => string 'more link text' (length=14)
