Complicated .htaccess rewrite question - advice needed

[davide101]

I've hit a real dead end here and would appreciate advice. I have a large series of files that have moved from:

/content/yyyy/mm/dd/title.php to:
/newdir/yyyy/mm/title.php

I need to redirect all traffic from the old location to the new location. Because I can't get rid of the dd, I'm using this rule temporarily:

RewriteCond %{REQUEST_URI} ^/content/
RewriteRule ^content/(.*)$ /newdir/$1 [R=301,L]

Any ideas on how I remove the /dd/ portion of the URL or is this impossible?

Thanks! After 2 hours of messing around, I'm losing my mind.

The solution:

RewriteRule ^content/([^/]+)/([^/]+)/[^/]+/([^/]+\.php) http://www.domain.com/newdir/$1/$2/$3 [L,R=301]
