How-to get the get_category_parents() breadcrumbs trail without link on last item

Question

Just a question : I want to use get_category_parents() to display a breadcrumb on a category archive page, but with no link on the current displayed category (SEO purposes, because they say that's a link to itself. I'm not sure search engines are that stupid, but anyway).

Like this :

link_home » link_cat1 » link_subcat1 » nolink_subsubcat1

get_category_parents() is perfect for that, but there's only two options : with links and without links.

What I want is links BUT on the last item.

The function is returning a string, not a object or array, so I cannot remove the last item.

I could do with regex by searching with the » separator and remove last link that way, but i'm pretty bad with regexes (if you know good references for that, i'm interested !).

I know the obvious answer is to create a custom function using get_ancestors() and a loop , then simply adding after the current category name.

But I wanted to know is there is some more simplier way, but just hooking get_category_parents() to not adding link to the last item ?

Thank you for any insight.
