Removing javascript codes while parsing a web page

Question

When capturing the contents of a web page, CURL or file_get_contents , which is the easiest way to remove the built-in javascrip codes. I am thinking of a regex to remove everything between tags; but regular expression 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 for this?

You can use DOMDocument and removeChild() . Something like the following should make you go.

 <?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(); ?>
