How to parse a forum post using PHP Simple HTML DOM Parser?

Question

PHP

I need help, I need to parse the text of messages from a forum thread of only 1 author.
For example, from the forum
only the author "sakakolm"

Answer 1

I would advise you to look in the direction of phpQuery, especially if you have ever worked with jQuery
Only I was too lazy to play with the encoding, but I think this will no longer be a problem :)

<?
require_once 'phpQuery.php';

$url = 'http://ruforum.mt5.com/threads/2494-obzor-valyutnogo-rinka-za-nedelyu';

$userName = 'almostsuper';


$htmlPage = file_get_contents($url);
$html = phpQuery::newDocument($htmlPage);

$posts = $html->find('.postdetails');


foreach ($posts as $var) {

  $userPost = pq($var)->find('.username > strong:contains('.$userName.')');
  if($userPost->text()==$userName)
  {
    echo '<h1>'.$userName.'</h1>';
    $postBody = pq($var)->find('.postbody');
    echo $postBody.'<hr/>';
  }

}

Answer 2

look for an example of using dom parser.
Or say what is the problem that served to write the question here.

Answer 3

I can't set a regular expression to parse a message with the id= user condition

Answer 4

One expression is not enough here. Something like this:

$rows = $html->find('ol#posts > li > div.postdetails > div.userinfo > div.username_container > div > a.username[href*=3606-sakakolm]');
foreach($rows as $row) {
  $msg_html = $row->parent()->parent()->parent()->next()->find('div.postrow > div.content');
}

It would be nice to use closest() instead of the parent() heap, but it seems to be absent in the PHP Simple HTML DOM Parser, as well as parents().
The code has not been tested, errors are possible. But I think the idea is clear.
