How to access to the content of a html element using PHP? -


this question has answer here:

i know how access content of html element using php. explanation below:

this html code:

<div id="edittitle" title="editing title"> <b>1</b> </div>

actually, want accessing content of <b> tag (which "1") using php , putting in php variable. there idea how that?

thanks in advance.

the following code should give idea how can use domdocument - xpath not required really:

        $strhtml='             <div id="edittitle" title="editing title">                 <b>1</b>             </div>';          libxml_use_internal_errors( true );         $dom=new domdocument('1.0','utf-8');         $dom->validateonparse=false;         $dom->loadhtml( $strhtml );         libxml_clear_errors();          $col=$dom->getelementsbytagname('b');         echo $col->item(0)->nodevalue;          /* output */         --> 1

to manipulate entire page below pseudo code should understand process. not tested of course ...

<?php     @ob_start();     session_start();      include 'file.php';     include 'otherfile.pphp'; ?>  <html>     <head>         <title>output buffering test</title>         <link rel='stylesheet' href='style.css' />         <script type='text/javascript'>             function blah(){              }         </script>     </head>     <body>         <h1>an attention grabbing headline</h1>         <div id="edittitle" title="editing title">             <b>contents1</b>         </div>     </body> </html>  <?php      libxml_use_internal_errors( true );     $dom=new domdocument('1.0','utf-8');     $dom->validateonparse=false;     $dom->loadhtml( @ob_get_contents() );     libxml_clear_errors();      $col=$dom->getelementsbytagname('b');     $your_variable=$col->item(0)->nodevalue;       $buffer=$dom->savehtml();     @ob_end_clean();      echo $buffer;      if( @ob_get_level() > 0 ) {         for( $i=0; $i < ob_get_level(); $i++ ) @ob_flush();         @ob_end_flush();     }     $dom=null; ?>

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
