How to preg_replace some ID's inside my PHP code?

Hi,
I have a script that import content into my website,and I want to replace some data.I can replace div classes,but not the ID's inside the classes.Example:

<div class="Content" id="i_need to remove that" data-shortlistID="I have to rename" data-natID="remove agian">

So,to remove the div class i use:

$html = preg_replace('#<div[^>]*class="Content"[^>]*>.*?</div>#is', '', $html);

To rename the div class i use:

$html = preg_replace('#(<div[^>]*class=")Content("[^>]*>.*?</div>)#is', '$1New-Content$2', $html);

But how can remove/rename the ID's inside <div class="Content" ?

I'm not coder,so please excuse me poor language
Thanks in advance

$html = preg_replace('#class="Content" id="(.*?)"#','',$html);  // replace with nothing or insert class="Content" between the empty '' quotes
$html = preg_replace('#data-natID="(.*?)"#','',$html);  // replace with nothing


$somethingelse = "something";  // new data-shortlistID

$html = preg_replace('#data-shortlistID="(.*?)"#','data-shortlistID="'.$somethingelse.'"',$html);  // renames data-shortlistID with $somethingelse
