regex in vimscript

Question

let test = 'a href="http://www.google.com">www.google.com</a;'

in vimscript, how can i get http://www.google.com out of this using a regexp, and store it in another variable?

i can't seem to find any documentation about this.

thanks in advance!

Answer 1

let url = matchstr(test, '\ca href=\([''"]\)\zs.\{-}\ze\1')
if empty(url) 
   throw "no url recognized into ``".test."''"
endif

For more information, see:

:h matchstr()
:h /\c
:h /\zs
:h /\{-
