Golf

Now for some fun ;-). A friend asked me for a Vim macro this morning to strip all but the text contained with the double quotes of a file with the following format:

<option value="Automotive">Automotive</option>
<option value="Banking">Banking</option>
<option value="Biotech">Biotech</option>

etc...

After the macro it would be:

Automotive
Banking
Biotech
etc...

Initially, I came up with the following sequence (macro storage command omitted):

df"f"d$j0 (9 chars)

This works fine, but my OCD kicked in, and I decided to make it shorter:

df"f"D+ (7 chars)

For a brief moment, I thought this was as short as I could make it, but then...

df"wD+ (6 chars)

As far as I know, this is the shortest possible macro to accomplish this task, but I would love to be proven wrong.

UPDATE:

My friend Chris Sutter has contributed another solution using text objects that is pretty nifty.

di"Vp (5 chars)

or if you want to jump to next line as with the previous 6 char macro:

di"Vgp (6 chars)

Good stuff... thanks Chris!
