ruby - delete from a string

I have the following strings:

src = "dav://w.lvh.me:3000/Home/Transit/file"
host = "w.lvh.me:3000"

What I want to obtain is "/Home/Transit/file" using those two strings

I thought of searching for host in src and delete it the first time it appears, and开发者_运维百科 everything before it, but I'm not sure exactly how to do that. Or maybe there's a better way?

Any help would be appreciated!

There is a better way indeed:

require 'uri'
src = "dav://w.lvh.me:3000/Home/Transit/file"
src = URI.parse src

src.path      # => "/Home/Transit/file"

When there are spaces in the string, you must pass extra step of escaping/unescaping. Fortunantly, this is simple:

require 'uri'
src = "dav://w.lvh.me:3000/Home/Transit/Folder 144/webdav_put_request"
src = URI.parse(URL.escape src)

URL.unescape(src.path)      # => "/Home/Transit/Folder 144/webdav_put_request"

This should do the job:

src = "dav://w.lvh.me:3000/Home/Transit/file"
host = "w.lvh.me:3000"
result = src.sub(/.*#{host}/, '')
#=> "/Home/Transit/file"
