Manipulating string with html tags using regex

Question

I have the string test1 test2 test3 span test4 and I want to put span tag surrounding the span word which position is after  without touching the existing span tag using javascript regex.

That sounds like manipulating HTML, which shouldn't really be done with regex, but with something that can actually parse HTML. — adeneo

@pattmorter - and that would replace the first span only, giving test1 test2 tes<span style ... — adeneo

str.replace(' span ', ' span ') ? With spaces surrounding span word. — Christian Benseler
