Regex pattern to match {{....}}

Question

I try to write regex pattern "\{\{.*\}\}" to match tags "{{...}}". But it alway match all string below:

{{  shortcode('') }} abc {{ shortcode('') }}

Please help me correct pattern to match each tag only, thanks for any help.

Answer 1

Try this:

\{\{(.*?)\}\}

Using ? will cause the match to stop at the first closing bracket.

Answer 2

You probably want to use capturing brackets around the text inside the tags. This will return the captured text.

"\{\{([^{}]+)\}\}"
