How do I replace a link between <a></a> and keep the link from href unchanged?

Question

How do I replace a link between and keep the link from href unchanged?

This is my code:

$str="Lorem Ipsum.<a href='https://test.be/assets/kcfinder/upload/files/certificat_auto.pdf'>https://test.be/assets/kcfinder/upload/files/certificat_auto.pdf</a>Lorem Ipsum ";

$pattern = '/>https:\/\/test.be\/assets\/kcfinder\/upload\/files\/.*\./';
$replacement = '>${1}';

echo preg_replace($pattern, $replacement, $str);

This is the output:

Lorem Ipsum.<a href='https://test.be/assets/kcfinder/upload/files/certificat_auto.pdf'>pdf</a>Lorem Ipsum 

I need the output to be :

Lorem Ipsum.<a href='https://test.be/assets/kcfinder/upload/files/certificat_auto.pdf'>certificat_auto.pdf</a>Lorem Ipsum 

I'm doing something wrong with the replacement, the pattern matches
