I have been getting this error when trying to parse HTML with a script

  • 0

I have been getting this error when trying to parse HTML with a script tag using PHP’s DOMDocument class.

Warning: DOMDocument::loadHTML(): Unexpected end tag : style in Entity, line: 71 in /var/www/signage-dev/dynaml/includes/page.php on line 95

I have even tried CDATA tags but it has resulted in the same error

My script tag is

<script type="text/javascript">
//<![CDATA[
document.write('<style type="text/css"> .printBTN { display: inline; } </style>');
//]]>   
</script>

This snippet is supposed to show a print button when JavaScript is enabled. I don’t believe this is the most effective way of doing this (the previous developers created this), but even so, I wish to find a solution to this problem since I may run into this problem again in the future and it may not be as easy to fix as this is.

    This question seems to have the solution Why split the tag when writing it with document.write()?

    I guess php DOM is more strict than most browsers. The solution I have seen sometimes is the one posted in a comment below the linked answer, escaping it with <\/script>, or in this case <\/style>, but I thought it was only necessary with script tags.
