Need Help to Redirect Mass URLS by .htaccess

I'm newbie in this forum and also in apache world,

I need help to redirect mass urls in new ones. I've study very useful tutorial about this but still can't redirect my urls correctly.

I have url like
http://www.domain.com/articles/video-audio/digital-camera/item/390-eyes-vs-camera
and I want to change the "articles/video-auto" to something else like "home/av" the 390 is the id of page and eyes-vs-camera is the description for SEF

I really appreciated for any kind advice.

 

So you just want to replace "articles/video-auto" with "home/av" in the URL?

 

Thank you for your reply

Yes, and the rest of the url should be in redirected url I mean (390-eyes-vs-camera) this part is dynamic

 

Try this code (not tested)

RewriteEngine On
RewriteRule ^articles/video-audio/digital-camera/item/([0-9]+)-(.*)$ http://www.domain.com/home/av/digital-camera/item/$1-$2 [R=301,L]

Code (markup):

 

Unfortunately this does not work.

right now my .htacess redirect portion is something like this

# RewriteBase /

RewriteEngine On
########## Begin -  core SEF Section
#
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/index.php
RewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.feed|\.pdf|\.raw|/[^.]*)$  [NC]
RewriteRule (.*) index.php
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
#
########## End - Joomla! core SEF Section
 RewriteRule ^articles/hardware-news/notebook/item/([0-9]+)-(.*)$ http://www.zoomit.ir/articles/notebook/item/$1-$2 [R=301,L]

Code (markup):

 

Any advice?
