How to get body content without javascript code

Question

To get content in the body tag, I'm using the code below.

$html = @file_get_contents($url);
$doc = new DOMDocument();
@$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('body');
$body = $nodes->item(0)->nodeValue;

How to remove js codes from the $body? Any js code that will look like

<script> /*Some js code*/ </script>

Try this:

$html = preg_replace("/<script.*?\/script>/s", "", $html);

When doing regex things might go wrong, so it's safer to do like this:

$html = preg_replace("/<script.*?\/script>/s", "", $html) ? : $html;

So that when the "accident" happen, we get the original $html instead of empty string.

This removes only the script tags, but leave the javascript content. The idea is to remove both the script tags and the javascript content. – lomse Jan 03 '16 at 19:43

If you already using DOMDocument then why won't you remove nodes with that?!

$dom = new DOMDocument;
$dom->preserveWhiteSpace = false;
@$dom->loadHTMLFile("from_link_to.html");
$scripts = $dom->getElementsByTagName('script');
foreach ($scripts as $script) {
    $scripts->removeChild($script);
}
...

Take closer look to The DOMDocument class and by the way regular expression is nightmare for such tasks.

The solution here has fixed my issue. The code below completely removes script tags and their content from the body tag:

$doc = new DOMDocument();
    $doc->preserveWhiteSpace = false;
    @$doc->loadHTML($html);
    $script = $doc->getElementsByTagName('script');

    $remove = [];
    foreach ($script as $item) {
        $remove[] = $item;
    }

    foreach ($remove as $item) {
        $item->parentNode->removeChild($item);
    }

    $node = $doc->getElementsByTagName('body');
    $body = $node->item(0)->nodeValue;

    echo $body;
