I am trying to do a modify a text which contain some special tags. I believe it should be possible by a single regular expression, but am stuck…

What I want to do is easier to explain by an example:

If I have this text:

{Lorem Ipsum} is simply {dummy text} of
the printing and typesetting industry.

I want as a result this:

<span>Lorem Ipsum</span> is <span>simply dummy</span> text of the printing and typesetting industry.

I a } is encountered with no previous matching { then it should be ignored.

I know I can match all inner texts with this \{(.*?)\} but am lost on how to proceed, any help would be appriciated.

    You are close.

    text = text.replace(/{(.*?)}/g, '<span>$1</span>')

    should do the trick. The g modifier makes replace to replace every occurrence of the pattern and $1 refers to the content of the first capture group.

    Btw. escaping the {} is not necessary here as {(.*?)} is not a special construct. It still might be better to escape them for clarity.

    More about regular expression in JavaScript in the MDN documentation.
