php – Wrap div around hyperlink (a tag)

I have a text with multiple links in it. One single link looks like

<a href=\"http://www.mydomain.com/files/test1.pdf\" target=\"_blank\">My link</a>

First, I would like to wrap div tag around all href tags but only if href is beggining with http://www.mydomain.com/files/. So the link above (because it starts with that prefix) should become

<div class=\"myLink\">
   <a href=\"http://www.mydomain.com/files/test1.pdf\" target=\"_blank\">My link</a>
</div>

Then depending on file extension (ending characters of the href) add an image before a link so it becomes

<div class=\"myLink\">
   <img src=\"pdf_file_icon.png\" alt=\"File type icon\" />
   <a href=\"http://www.mydomain.com/files/test1.pdf\" target=\"_blank\">My link</a>
</div>

And optionally add some my text after the link so the final version becomes

<div class=\"myLink\">
   <img src=\"pdf_file_icon.png\" alt=\"File type icon\" />
   <a href=\"http://www.mydomain.com/files/test1.pdf\" target=\"_blank\">My link</a>
   <span class=\"fileSize\">1.3 Mb</span>
</div>

I need solution for both PHP and JavaScript/jQuery (I think it\’s easier for jQuery because of it\’s selector capabilites?).

---

What I want to get is to move from regular text link to something like this (don\’t bother with file size, it\’s pre-calculated so it\’s just like any other regular/dummy text)

Edit #1

Here is my try in PHP

$regexp = \"<a\\s[^>]*href=(\\\"??)(http:\\/\\/www\\.mydomain\\.com\\/files\\/[^\\\" >]*?)\\\\1[^>]*>(.*)<\\/a>\";
$text = preg_replace(\"/$regexp/siU\", \"<div class=\\\"fileAttachment\\\"><img src=\\\"pdf_file_icon.png\\\" alt=\\\"File type icon\\\" /><a href=\\\"$2\\\" target=\\\"_blank\\\">$3</a></div>\", $text);

But I\’m not sure how immediately to check for file extension and depending on it insert appropriate image (pdf_file_icon.png)?
