Re: Find and replace with regex

You could use a negative look-ahead assertion (see perlre) $sample =~ s{(img src=")(?!http)}{$1$http}g; which gives the following output:

<img src="http://domain.com/pics/local.jpg" alt="" />
<img src="http://remote.com/pics/remote.jpg" />
more confusion, just in case: 3:00pm 12/12/12
other urls <a href="http://fake.com">
http://fake.com</a>

But it's probably fraught with danger.

Looks good to me. What dangers do you see, besides having a folder or file named "httplaces" for example? I think this solution works best. :)	[reply]

It's just too fragile. Consider `<img src="..." />` [download] as just one simple example that breaks the previous regexp.	[reply] [d/l] [select]
