How to remove attributes html and replace an another attributes?

Question

I have a string like this:

<p>title="abc" </p> <p title="a"><a title="b"></a></p><pre title="c"></pre>

I want to replace string title is class inside html tag and keep string 'title' outside html tag. Please tell me if you have any ideas. Thanks.

You could use PHP's DOM implementation, specifically the [Document Fragment](http://php.net/manual/en/class.domdocumentfragment.php) part. Parse it into DOM, manipulate it, then serialise it back into HTML. — Félix Saparelli, Dec 14 '15 at 11:11

If you want to do this with PHP, you should use DOMDocument. Maybe this SO post can help you.

edit : sorry for the linked-only answer. Here is a example of code :

$html = '<p>title="abc" </p><p title="a"><a title="b"></a></p><pre title="c"></pre>';
$dom = new DOMDocument;
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$nodes = $dom->getElementsByTagName('*');

foreach ($nodes as $node) {
    if ($node->getAttribute('title')) {
        $node->setAttribute('class', $node->getAttribute('title'));
        $node->removeAttribute('title');
    }
}
$html = $dom->saveHTML();
echo $html;

This code will give you :

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><p>title="abc" </p><p class="a"><a class="b"></a></p><pre class="c"></pre></body></html>

You can then remove header + extra tags (html/body) if you don't need it. Online example here
