Question

When capturing the content of a webpage by CURL or file_get_contents, What is the easiest way to remove inline javascrip codes. I am thinking of regex to remove everything between tags; but regex is not a reliable method for this purpose.

Is there a better way to parse an html page (just removing javascript codes)? If regex is still the best option, what is the most reliable command to do so?

Answer 1

You can make use of DOMDocument and its removeChild() function. Something like the following should get you going.

<?php

$doc = new DOMDocument;
$doc->load('index.html');

$page = $doc->documentElement;

// we retrieve the chapter and remove it from the book
$scripts = $page->getElementsByTagName('script');
foreach($scripts as $script) {
   $page->removeChild($script);
}

echo $doc->saveHTML();
?>
