php - RegEx for matching a HTML string

760

I'm trying to do apreg_match_all, which does not work.

preg_match_all(
  '!<div itemprop="description"><p><span ><span ><span >(.*?)</span></span></span></p></div>!',
  $html,
  $matches1,
  PREG_SET_ORDER
);
foreach ($matches1 as $soge2){print_r($soge2);}

How do I make it work?

Solution:

It may not be the best idea to parse HTMLs with RegEx, which seems that you may want to do. However, based on your question, I'm guessing that you may wish to get all data from this tag using (.*):

<span class="page_speed_1632894595"></span>

It is possible to do so. First, you may design yourpreg_match_all(); based on:

preg_match_all($pattern, $subject, $matches);

which in this case, your subject is your HTML input, and I'm not sure, but your pattern might be:

/<span style=\"font-size:14px;\">([\w\s]+)(<\/span>)/s

Code

$html = '<div itemprop="description"><p><span ><span ><span >Alphanumeric Words If You Wish To Match</span></span></span></p></div>';

preg_match_all('/<span style=\"font-size:14px;\">([\w\s]+)(<\/span>)/s', $html, $matches1, PREG_SET_ORDER);
var_dump($matches1);

foreach ($matches1 as $soge2) {
  print_r($soge2);
}

Output

Array
(
    [0] => <span class="page_speed_1632894595">Alphanumeric Words If You Wish To Match</span>
    [1] => Alphanumeric Words If You Wish To Match
    [2] => </span>
)
