I'm trying to make an url that adds a / to all hrefs and srcs in a string. It should only add a / to urls that don't have a http:// at their beginning and that don't have / yet also.

If we have this:

<a href="ABC">...
<img src="DEFG">...
<a href="/HIJ">...
<a href="http://KLMN">...

The results should be something like this:

<a href="/ABC">...
<img src="/DEFG">...
<a href="/HIJ">...
<a href="http://KLMN">...

This is what i've come up till now:

&(href|src)="?!(\/|http::\/\/)(.+)"

And the replace would be

$1="/$2"

It isn't working, though.

• What am I doing wrong?
• How would the working regex have to look like
