Echo the Last Child Taxonomy only (not parents)?

Question

I have a question about how to echo a child taxonomy only.

My taxonomy is location.

I have a parent location and child locations like so:

London (parent)

• West London (Child)

  • Chelsea (Grandchild)

I need to echo just the last term (in the case above, it's Chelsea).

At present the code I am using is:

$terms_as_text = get_the_term_list( $post->ID, 'location', '', ', ', '' ) ; echo strip_tags($terms_as_text);

Unfortunately, this echo's both parens/superiors as well.

How would i display just the last child term?

Many Thanks in advance

Try something like this:

$terms_as_text = get_the_term_list( $post->ID, 'location', '', ', ', '' ) ; 
$terms_arr = explode('some-delimiter',$terms_as_text);
echo end($terms_arr);
