url = "

http://www.ingolfwetrust.com/golf-central/content/binary/Davis-Love-III.jpg"
filename = url.scan(/[^/]+/).last

This looks for all sections of the string that do not contain a slash
and
picks the last one.

There are probably dozens of ways to do this. Here is a simple way that
does use regular expressions:

url.split("/").last

filename = url.scan(/[^/]+/).last

aggbug.ashx?id=56f9e33a-6333-4daf-b4e1-137ddc051adf">

What do you want to do with
aggbug.ashx?id=56f9e33a-6333-4daf-b4e1-137ddc051adf ? Are you using it ?
If not , for the rest of the pictures , you could be calling
File.basename on them and get the last part only . For example , on
http://www.ingolfwetrust.com/golf-central/content/binary/Davis-Love-III.jpg
you will receive Davis-Love-III.jpg .

sorry yar …Nothing Work On That.I get nil value

Any ways i used this expression to extract the imgage url =>
(/<img.*?>/)
It has given me image url.
But I want to get all the url’s based on file extensions like jpg and
png…
That Is… if it contains image file extension,Only those image urls
has to fetched

Help Me

#!/usr/bin/ruby

require ‘rubygems’
require ‘hpricot’

ext = %w( .jpg .png .gif … )
Hpricot(DATA.read).search(“img”) do |img|
name = File.basename(img.attributes[‘src’])
puts name if ext.include?(File.extname(name))
end

END
[~]$ blah


#=>
foo.jpg

Another way to extract the URL and get only the path:

require ‘uri’

tag = ‘’
File.basename(URI.split(URI.extract(b)[0])[5])
=> “aggbug.ashx”

Then you can check with File.extname to check for the extensions you
want, as others have shown.

Hope this gives you other ideas,

How did you do with the pattern we already suggested, with “.*?.jpg” in
it?

Can you run another pass with “.*?.png” too?
