I need to learn how to remove html tags using PHP.
This is what I have in mind (I think DOM phrasing is what I need but I cant figure out how it works. A working example would be a big help for me. I can't install any external library’s and I am running PHP 5):
function the_remove_function($remove){
// dom parser code here?
return $remove;}
// return all content into a string
ob_start('the_remove_function');
Example code:
<body>
<div class="a"></div>
<div id="b"><p class="c">Here are some text and HTML</p></div>
<div id="d"></div>
</body>
Questions:
1) How do I return:
<body>
<p class="c">Here are some text and HTML</p>
</body>
2) How do I return:
<body>
<div class="a"></div>
<div id="b"></div>
<div id="d"></div>
</body>
3) How do I return:
<body>
<div class="a"></div>
<p class="c">Here are some text and HTML</p>
<div id="d"></div>
</body>
Next example code:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel='stylesheet' id='test-css' href='http://www.domain.com/css/test.css?ver=2011' type='text/css' media='all' />
<script type='text/javascript' src='http://www.domain.com/js/test.js?ver=2010123'></script>
</head>
4) How do I return:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel='stylesheet' id='test-css' href='http://www.domain.com/css/test.css?ver=2011' type='text/css' media='all' />
</head>
5) How do I return:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script type='text/javascript' src='http://www.domain.com/js/test.js?ver=2010123'></script>
</head>
Thanks for reading :)
You can use all the DOM classes of PHP, you will the doc here : https://www.php.net/manual/en/book.dom.php and I'm sur you can find a lot of tutorial in you prefer.
Here is an exemple for your second case :
<?php
$content = '<body><div class="a"></div><div id="b"><p class="c">Here are some text and HTML</p></div><div id="d"></div></body>';
$doc = new DOMDocument();
$doc->loadXML($content);
//Get your p element
$p = $doc->getElementsByTagName('p')->item(0);
//Remove the p tag from the DOM
$p->parentNode->removeChild($p);
//Save you new DOM tree
$html = $doc->saveXML();
echo $html;
//If you want to delete the first line
echo substr($html, strpos($html, "\n"));
