javascript - In D3, how can I select specific children elements of current node in zoomable treemap?

I'm trying to access children nodes of currently zoomed in cell in D3 zoomable Treemap. Specifically, I'd like to replace the href attribute in nested image nodes.

Is there a way of selecting just the children elements of the current node inside function zoomed(d){}, ideally without filtering the whole treemap, i.e. by utilising node.children property?

Something like this:

function zoomed(d) {

  // get children nodes data
  const currentChildren = d.children; // [Zh, Zh, Zh] - ok

  // select all children of current node
  // and select their image nodes
  // then update href attribute
  d3.select(this)
    .select(d => d.children)
    .selectAll("image")
    .attr("href", d => "/img/" + d.data.image);

}

Each cell structure is this:

g
  rect
  clipPath
  svg
    image
