regex: insert a break between the text and tag img

Question

I would like to insert a break after any text before few or one img tag:

I have a text:

Some text, some text <img src="thumb.jpg" /><img src="thumb2.jpg" />

I would like to get:

Some text, some text <br /><img src="thumb.jpg" /><img src="thumb2.jpg" />

I would like to make it through the regular expression in Ruby using the gsub method.

Based on what you are saying shouldn't it be "Some text, some text

" ? Notice the second
tag. — coolmine, Mar 25 '13 at 12:51

Maybe this?

str.gsub(/((?:<img[^>]+>)+)/, '<br />\1')

Depends on how you define text, you might need some alteration on the Regexp to make a correct substitution.

It sounds like you should actually use sub instead of gsub, so that it only changes the first instance of the <img> tag that you encounter:

s.sub(/<img/, '<br /><img')
