Parse your xml with dom, getAttribute('href') for specific nodes, create the new link decoding the current link, and set the attribute with the new link.

After that, save your edits.

Use urldecode: http://php.net/manual/en/function.urldecode.php to convert. How you go about extracting and replacing in the output depends on what tools your are using for that.
