Saving results of Regex Search into a file with Vim

Question

I've got a HTML file, and I'd like to grab all the links that are in the file and save it into another file using Vim.

I know that the regex would be something like:

:g/href="\v([a-z_/]+)"/

but I don't know where to go from here.

Answer 1

Jeff Meatball Yang was almost there.

As Sasha wrote if you use w it writes the full original file to the outfile

To only write the matched line, you have to add '.' before 'w':

:g/href="\v([a-z_/]+)"/ .w >> outfile

Note that the outfile needs to exists.

Answer 2

clear reg:x

qxq

search regex(whatever) and append to reg:x

:g/regex/call setreg('X', matchstr(getline('.'), 'regex') . "\n")

open a new tab

:tabnew outfile

put reg:x

"xp

write file

:w
