php regex to get string inside href tag

I have a text file where there are multiple occurrences of href tag.

I wish to get the content of these 

href='...'
and print it to screen.

How can I achieve that? The main problem is writing a correct regex.

    @EliasVanOotegem grabbing hrefs in a given html file isn't really "parsing html", and if you know what the HTMl is going to look like (for example a flat list of links), it might be better to use regexes than a full-blown parser. – Quentin Pradet Sep 04 '12 at 11:49
  • @Cygal: in rare cases, you could be right, but regex's will only take you so far, parsing the string is just so much more reliable – Elias Van Ootegem Sep 04 '12 at 11:52

Here you go:

$pageData = file_get_contents('your.txt');
if(preg_match_all('/<a\s+href=["\']([^"\']+)["\']/i', $pageData, $links, PREG_PATTERN_ORDER))
    $all_hrefs = array_unique($links[1]);

Now you have all unique hrefs in $all_href;

if you want to display them:

foreach($all_href as $href)
{
echo $href;
}

-1
preg_match_all('|<a href="(.+)">|', $file_content, $matches);
print_r($matches);

Not tested, but should work
