Replacing quote marks around strings in Vim?

Question

I have something akin to and need to change the single quotation marks to double quotation marks. I tried :s/\\\'.*\\\'/\

Answer 1

You need to put round brackets around the part of the expression you wish to capture.

s/\'\(.*\)\'/"\1"/

But, you might have problems with unintentional matching. Might you be able to simply replace any single quotes with double quotes in your file?
