<action name="countchild">
for(set(i,0),i LT ??,inc(i), set(layer[get(i)].url,subtxt("image",get(i),".jpg"); )
</action>

?? = 3
layer[0] -> layer[a]
layer[1] -> layer[b]
layer[2] -> layer[code=c]

Code

<layer name="a">
  <layer name="b"/>
  <layer name="c"/>
  <layer name="d"/>
</layer>

Code

<action name="countchild">
set(parent_a_counter,0);
for(set(i,0),i LT layer.count,inc(i),	
  if(layer[get(i)].parent EQ 'a',
  inc(parent_a_counter);set(layer[get(i)].url,subtxt("image",get(get(i)),".jpg"););
  );
);
trace('Total numbner of children:',get(parent_a_counter));
</action>

Taken from https://krpano.com/docu/actions/#arrays:

Quote

Every xml element with a name attribute is an element / item of an Array

In this case surely layer[a], in the OP's example, should be an array?

I would love to access layer[a].count and also a child object, using layer[a][0], but it doesn't seem to work.

Please could someone clarify the situation and give me a pointer if it is just a problem with my syntax?
