I am trying to remove script tags from HTML using PHP but it doesn’t

  • 0

I am trying to remove script tags from HTML using PHP but it doesn’t work if there’s HTML inside the javascript.

For example, if the script tags contain something like this:

function tip(content) {
        $('<div id="tip">' + content + '</div>').css

It will stop at </div> and the rest of the script will still be taken into account.

This is what I have been using to remove the script tags:

foreach ($doc->getElementsByTagName('script') as $node)
{
    $node->parentNode->removeChild($node);
}

    How about some regex-based pre-processing?

    Example input.html:

    <html>
  <head>
    <title>My example</title>
  </head>
  <body>
    <h1>Test</h1>
    <div id="foo">&nbsp;</div>
    <script type="text/javascript">
      document.getElementById('foo').innerHTML = '<span style="color:red;">Hello World!</span>';
    </script>
  </body>
</html>

    Script tag removing php script:

    <?php

    // unformatted source output:
    header("Content-Type: text/plain");

    // read the example input file given above into a string:
    $input = file_get_contents('input.html');

    echo "Before:\r\n";
    echo $input;
    echo "\r\n\r\n-----------------------\r\n\r\n";

    // replace script tags including their contents by ""
    $output = preg_replace("~<script[^<>]*>.*</script>~Uis", "", $input);

    echo "After:\r\n";
    echo $output;
    echo "\r\n\r\n-----------------------\r\n\r\n";

?>
