Search and Replace Text in Feeds to be New Ones

[Maelo terkim]

Hello

I have ~500 feeds as follows ( per example )

http://MY_OLD_LINK/NUMBER

and I want to change by

http://MY_NEW_LINK/NUMBER

changing text MY_OLD_LINK by MY_NEW_LINK in all feeds

because the old link changed to new link ( posibly will change in the future too :( )

is there any easy way to do it?

Search and replace text in feeds to be new ones?

¿Exists this pluguin of search and replace?

I think that if not done, would be a much needed pluguin

Idont know if this question is better here or in Developers or Open Discussion or can send to rssOwl in another way :(
