Not sure how you could retrieve the captured group with findRE .

You’d need something like a match list/map/dictionary that you can access. Go seems to have the required functionality, but it is apparently not exposed in Hugo.

There’s an example on how to work with capturing groups here:

Performing functions on a captured group in replaceRE

I think it’s not possible to do what you want in exactly the same manner. But you can “extract” each subgroup into a different var and work on that … (below is not tested … but you will get the idea): {{ $subgroup1 := .Content | replaceRE "(?U)<h2>(.*)</h2>" "${1}" }} {{ .Content | replaceRE "(?U)<h2>(.*)</h2>" (printf "<h2 id='%s'>%s</h2>" (anchorize $subgroup1) $1) | safeHTML }} It’s not efficient, but it seems to be at least doable. I am actually doing something like that in one of my th…

That’s clumsy (to use a friendly term). A more complete support for REs in Hugo would probably be nice.
