Does anybody know if a modified strip_tags function exsists where you can specify the ID of the tags to be stripped, and possbile also specify to remove ALL THE DATA IN THE TAGS. Take for example:
<div id="one">
<div id="two">
bla bla bla
</div>
</div>
Running:
new_strip_tags($data, 'two', true);
Must return:
<div id="one">
</div>
Is there something like this out there?
You can use DOMDocument and DOMXPath for that.
<?php
$html = '<html><head><title>...</title></head><body>
<div id="one">
<div id="two">
bla bla bla
</div>
</div>
</body></html>';
$doc = new DOMDocument;
$doc->preserveWhiteSpace = false;
$doc->loadhtml($html);
$xpath = new DOMXPath($doc);
$ns = $xpath->query('//div[@id="two"]');
// there can be only one... but anyway
foreach($ns as $node) {
$node->parentNode->removeChild($node);
}
echo $doc->savehtml();
That's not exactly what strip_tags does, it strips the tags but leaves the content. What you want is something like this:
function remove_div_with_id($html, $id) {
return preg_replace('/<div[^>]+id="'.preg_quote($id, '/').'"[^>]*>(.*?)<\/div>/s', '', $html);
}
Note that this will not work correctly with nested tags. If you need that, you might want to use a DOM representation of your HTML.
