Just to be perfectly clear. If the structure is like this

```julia
**subhead**

subrow
  p
  p
  p

**subhead**

subrow
  p
  p
subrow
  p
subrow
  p

**subhead**

subrow
  p
subrow
  p

```

the desired output is `[3,4,2]`? Indentations means “child of”.

Maybe

```julia
function countp(body::HTMLNode)
   i = 0
   counts = Int[]
   for e in body.children
     if e isa HTMLElement{:div} && get(e.attributes, "class", "")=="ttt-subhead"
       push!(counts, 0)
       i += 1
     end
     counts[i] += length(eachmatch(Selector("div.ttt-row > p"), e))
   end
   counts
end

```

</div>

I appreciate your help, but the code output is empty.

Could it be because there is a misunderstanding. The “ttt-subhead” are essentially “islands”, and so are the clusters of “div.ttt-row \> p”.

Maybe because you passed in the root node, not the body? My bad. Poor naming.
