Dear all,

i have a html file in my local path.

In that html file i have below tag.

![](https://www.ruby-forum.com/2010-01-12/Capture/1210420100112145725141.jpg)

Now what i need is i want to modify the above tag into

![](https://www.ruby-forum.com/Capture/1210420100112145725141.jpg)

i want to replace all the image path like above path.

Is it possible to do? i have a idea in hpricot parser.

Is it worth to try with hpricot…

if so,kindly provide any sample code or links

Thank you for your time

Here’s a hpricot example that works:

require ‘rubygems’  
require ‘hpricot’

doc = Hpricot(“

\<img  
src="/2010-01-12/Capture/1210420100112145725141.jpg"  
/\>

”)

doc.search(‘img’).each do |img|  
img[‘src’] = img[‘src’].gsub(/^/\d{4}-\d{2}-\d{2}/, “”) # have to do  
gsub  
– gsub! doesn’t work  
end

puts doc.html

Anyone, if this can be done smarter, please write.
