gedit: search and replace with regular expressions

From the standard Replace box (Control+H) you can use a little grouped regex to handle this:

• Search for: .*\| (.*) \|.*
• Replace with: \1
• Check the box that has "Match as regular expression"

This is on Gedit 3.10.4, the default version in Ubuntu 14.04.

You can use the plugin advanced-find for gedit.

Install the plugin from here.
