Regex to exclude match

Question

I know this has been asked before, but I just couldn't get mine to work. Using this example, Im trying to get the template variable but not if its used in some kind of tag.

{{ callMe() }}

<img src="{{ callMe() }}" />

Should match the first one, {{ callMe() }} but not the second. Ive been tinkering with negative lookahead, but not sure if i understand it. Here's my regex. Can anyone please have a look. Thanks.

(?!<.+\/?>)(({{.*([\w\.]+)\(.*\).*}}))

Does this answer your question? [RegEx match open tags except XHTML self-contained tags](https://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags) — adamkgray, Jul 13 '20 at 08:29
Could you tag language which you use to regex? There is many regex versions. — Leszek Mazur, Jul 13 '20 at 08:31

(?<!<.*){{.*([\w\.]+)\(.*\).*}}(?!.*>)

Need to check there's no < before and no > after

(?<!<[^>]*){{.*([\w\.]+)\(.*\).*}}(?![^<]*>)

would also check for <p>{{ callMe() }}</p>
