how fetch only part of html page

Question

hi all my sample code is below :

  <?php 
  $html = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  <title>samplecode</title>
  </head>
  <body>
    <div id="warrper">
      <div class="box-title">This title is sample</div>
      <div class="box-maim">
        <div class="box-element-1">
           <ul>
              <li>sample 1</li>
              <li>sample 2</li>
              <li>sample 3</li>
              <li>sample 4</li>
              <li>sample 5</li>
           </ul>
        </div>
        <div class="box-element-1">
           <ul>
              <li>sample 1</li>
              <li>sample 2</li>
              <li>sample 3</li>
              <li>sample 4</li>
              <li>sample 5</li>
           </ul>   
        </div>
        <div class="box-element-1">
           <ul>
              <li>sample 1</li>
              <li>sample 2</li>
              <li>sample 3</li>
              <li>sample 4</li>
              <li>sample 5</li>
           </ul>
        </div>
      </div>
    </div>
  </body>
  </html> ';

   preg_match( '/<div class="box-maim">(.*?)<\/div>/si' , $html , $match );

   print_r($match);
  ?>

my aim after load html from url is , fetch just only tag part of selected class for example below code :

  <div class="box-element-1">
     <ul>
        <li>sample 1</li>
        <li>sample 2</li>
        <li>sample 3</li>
        <li>sample 4</li>
        <li>sample 5</li>
     </ul>
  </div>
  <div class="box-element-1">
     <ul>
        <li>sample 1</li>
        <li>sample 2</li>
        <li>sample 3</li>
        <li>sample 4</li>
        <li>sample 5</li>
     </ul>   
  </div>
  <div class="box-element-1">
     <ul>
        <li>sample 1</li>
        <li>sample 2</li>
        <li>sample 3</li>
        <li>sample 4</li>
        <li>sample 5</li>
     </ul>
  </div>

but i dont know the correct methods of this action for that part .

You can do it with javascript or jQuery or you can use PHP Simple HTML DOM Parser (http://simplehtmldom.sourceforge.net/) for PHP. — Konsole, Sep 27 '13 at 05:20
@Console I am curious why do you suggest simplehtmldom if you have DomDocument and SimpleXML available by default on most installations of PHP this days. Is there a particular reason or just preference? — Prix, Sep 27 '13 at 05:26
Then read the link above it shows how to use it and also have 3 links showing how to use it for specific things. There are very few and specific cases where you would like to use regex to parse HTML and believe me, yours isn't one of it. — Prix, Sep 27 '13 at 05:31
A basic usage example can be found in [Grabbing the href attribute of an A element](http://stackoverflow.com/questions/3820666/regular-expression-for-grabbing-the-href-attribute-of-an-a-element/3820783#3820783) and a general conceptual overview can be found at [Noob question about DOMDocument in php](http://stackoverflow.com/questions/4979836/noob-question-about-domdocument-in-php/4983721#4983721). — Prix, Sep 27 '13 at 05:35
@rezataslimi_edu There's plenty of help already out there, including documentation. Just search for it. — BLaZuRE, Sep 27 '13 at 05:35
[How to use the DOM extension has been covered extensively on StackOverflow](http://stackoverflow.com/search?q=DOM+HTML+%5bPHP%5d&submit=search), so if you choose to use it, you can be sure most of the issues you run into can be solved by searching/browsing Stack Overflow. — Prix, Sep 27 '13 at 05:35

As all suggested to use DOM, try the below code:

<?php
$html = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  <title>samplecode</title>
  </head>
  <body>
    <div id="warrper">
      <div class="box-title">This title is sample</div>
      <div class="box-maim">
        <div class="box-element-1">
           <ul>
              <li>sample 1</li>
              <li>sample 2</li>
              <li>sample 3</li>
              <li>sample 4</li>
              <li>sample 5</li>
           </ul>
        </div>
        <div class="box-element-1">
           <ul>
              <li>sample 1</li>
              <li>sample 2</li>
              <li>sample 3</li>
              <li>sample 4</li>
              <li>sample 5</li>
           </ul>   
        </div>
        <div class="box-element-1">
           <ul>
              <li>sample 1</li>
              <li>sample 2</li>
              <li>sample 3</li>
              <li>sample 4</li>
              <li>sample 5</li>
           </ul>
        </div>
      </div>
    </div>
  </body>
  </html> ';

$dom = new DOMDocument();    
$dom->loadHTML($html);    
$xpath = new DOMXPath($dom);    
$div = $xpath->query('//div[@class="box-maim"]');    
$div = $div->item(0);    
echo $dom->saveXML($div);    
?>

It works perfectly :)

When will people stop using regex for dom manipulation... – EJTH Sep 27 '13 at 05:37
thanks but tag body is not end always – rezataslimi_edu Sep 27 '13 at 05:38
@rezataslimi_edu more reason not to use a regex but a proper library that is meant for parsing HTML and is/was used/tested by millions of programmers. – Prix Sep 27 '13 at 05:38
oh then do preg_match_all for
.
– Vishnu Sep 27 '13 at 05:39
my english grammar is weak , i sorry for it . – rezataslimi_edu Sep 27 '13 at 05:39
hey EJTH and @rezataslimi_edu : i know preg_match is not recomened, but it comes handy for quick small tasks :P – Vishnu Sep 27 '13 at 05:40
@VishnuVishwa his quick and small task seems to have turned into a nightmare he can't solve and resulted in him posting it here for help and the fact he doesn't want to read anything else just means he wants to be spoonfed with the answer. – Prix Sep 27 '13 at 05:41
@rezataslimi_edu : edited answer please check. – Vishnu Sep 27 '13 at 05:44
@Prix : hey prix i am not pro to teach him stuffs, just an quick help...If he really not interested to learn stuffs , we cant force him to – Vishnu Sep 27 '13 at 05:45
@VishnuVishwa sure why not, its better to answer him and get 15 points then to point him on the right direction ;) so he can learn it. – Prix Sep 27 '13 at 05:47
@Prix : the thing is i myself dont know the right direction :P , as you guys said about DOM manipulation i am looking at them now :P – Vishnu Sep 27 '13 at 05:49
@VishnuVishwa glad this discussion at least made you read and check it out, there is a variety of libraries where DomDocument and SimpleXML are by default installed with most versions of PHP so they are ready to use. – Prix Sep 27 '13 at 05:49
my target is not class="box-element-1" ,my target is everything inner class="box-maim" – rezataslimi_edu Sep 27 '13 at 05:53
Vishnu Vishwa thank for try answer me – rezataslimi_edu Sep 27 '13 at 05:55
@prix : I used DOM now :) – Vishnu Sep 27 '13 at 06:05
@VishnuVishwa and you have my down vote removed. – Prix Sep 27 '13 at 06:07

If I am getting you properly, just do simply like that:

preg_match_all('/<div\s[^>]*class=\"box-element-([^\"]*)\"[^>]*>(.*)<\/div>/siU', $html, $matches, PREG_SET_ORDER);
echo '<pre>';
print_r($matches);
