Hey Guys

I am trying to remove all the relative image path slashes from a chunk of HTML that contains several other elements.

For example

<img src="../../../../images/upload/1/test.jpg />

would need to become

<img src="http://s3.amazonaws.com/website/images/upload/1/test.jpg" />

I was thinking of writing this as a rails helper, and just passing the entire block into the method, and make using Nokogiri or Hpricot to parse the HTML instead, but I don't really know.

Any help would be great

Cheers Adam
