Nested arrays in parser with conditional rendering

Hi,

I´d like to apply a conditional rendering in a nested iterator:

Code:

{parent}
  {children}
    {if $child->someAttribute == "1"}
      HELLO!
    {endif}
  {children}
{/parent}

I tried to use a static index and it works, but would be necessary to know the current iterator index

Code:

{parent}
  {children}
    {if $parent[0]->children[0]->someAttribute == "1"}
      HELLO!
    {endif}
  {children}
{/parent}

If there was something like:

Code:

{if $parent[$parent_idx]->children[$children_idx]->someAttribute == "1"}

Is this possible? There is any workaround?

Thanks in advance!
