Regex

Question

I have the following code.

<a href="/29486389/Author_-_Name_of_Song.mp3/" class="popover-with-html hidden-phone">Andra - Inevitabil va fi bine.mp3</a>

How can I replace this string, using regex, but without losing a part from string. To looks like this

<a href="melodie/Author_-_Name_of_Song.mp3.html/" class="popover-with-html hidden-phone">Author - Name of Song</a>

I know i need to use a pattern like that:

$string = 'April 15, 2003';
$pattern = '/(\w+) (\d+), (\d+)/i';
$replacement = '${1}1,$3';

Thank you very much.

Why not simply use a DOM object? Parsing html with regex is never a clean job. — Maxim Kumpan

You could use the following regex, note that to remove the underscore in Author - Name of Song is very difficult if not impossible with one regex (dynamically). — HamZa

PHP code

$pattern = '#<a\s+href="/\d+/(.+?)_-_(.+?)\.mp3/"\s+class="popover-with-html hidden-phone">.+?</a>#is';
$replacement = '<a href="melodie/$1_-_$2.mp3.html/" class="popover-with-html hidden-phone">$1 - $2</a>';

$my_clean_html_code = preg_replace($pattern, $replacement, $my_html_code);

Thank you very much, but if the name of song/author contains dots, the script doesn't work well anymore.

Is it possible to have underscores ('_') in the song/author?
