Use an editor with regex support to clear all matches of:
<artifact[\s]+[^>]*>(.(?!<[/]?artifact>))+Pack200Unpacker(.(?!<[/]?artifact>))+[\s]*</artifact>

To clear the blank lines, first regex replace with empty strings the matches of:  
^[\s]*$
and then do an extended replace from \r\n\r\n to \r\n

Modify the total artifacts count by searching for matches of:
<artifact[\s]+[^>]*>
