How can I mass delete multilingual strings when I know only the page that added them? Some inappropriately placed t() functions generated a large number of strings that I do not want to translate.  Unfortunately, using the Refresh strings i18n page does not clear these strings.

On the Translate interface page, I can search for the strings one by one and delete them but there are about a hundred so I would prefer to do it another way.  Thankfully, they were all created on two pages, so I can search by the path (/ja/mypage) and delete them that way.  However, I still have to click each link.

Is there a faster way?
drush sql-query "delete from locales_source where location = '/ja/mypage'"


Or delete by strings, for examples if all strings you want to delete contains "hoof" : 

drush sql-query "delete from locales_source where source like '%hoof%'"
