Delete the content in the article - wordpress

[kdaica]

Anyone who can help, I need to delete the content in my wordpress post, it looks like this:
For example, I have an article included,
Image
Download Link
Video

I need to delete the "download link", of course I can delete it manually, but the problem is there are over 2000 posts.
Any plugin, script, or anything that can help me how to do this, please let me know

There are some plugins for this, if you can't get that to work you can always S&R in your database.

-Can you tell me more about S & R does not. Actually, I do not know what to do with the database

-----------
The download link for each different movie, so I can not search & replace

search: ryushare.com
replace: (blank)

that's the easiest way I can think of :D

Do a regex search and replace in your posts. One such plugin: http://wordpress.org/plugins/search-regex/
