If you for any reason would like to add attributes to your breadcrumb links, this is how i did it; instead of

print $breadcrumb;

i did

print str_replace('">', '" target="_top">', $breadcrumb);

I needed this because i created a template with frames for external links. The top of the frame uses the standard "header" region, the bottom uses an external link. This snippet makes sure that when i click on a breadcrumb link, it will open in the "_top". You could use this to add any odd attribute though. I welcome cleaner methods, this worked for me though. It took me a while to figure this out so i thought i'd share.

Perhaps a Better Way

more "clean" way is to override theme function in template.php, insted of making breadcrumb changes in page.tpl.php

example: (template.php)

function mytheme_breadcrumb($breadcrumb) {
  $sep = ' > ';
  if (count($breadcrumb) > 0) {
    return implode($breadcrumb, $sep) . $sep;
  }
  else {
    return t("Home");
  }
}

or other example: (template.php)

function phptemplate_breadcrumb($breadcrumb) {
  if (!empty($breadcrumb)) {
    return '<div class="breadcrumb">'. implode(' » ', $breadcrumb) .'</div>';
  }
}

Hello,
This is how you added attributes, but what if you want to delete some ? I'm wondering how could I get rid of the attribute title in the of the the breadcrumb ?

Re-hello,
I didn't find the drupal way, but did it the "PHP way"...
I was trying to remove the "title" attribute, but this solution can be used for any attribute.

In template.php I added in my function MYTHEME_breadcrumb() like this:

function MYTHEME_breadcrumb($variables) {
  $breadcrumb = $variables['breadcrumb'];
  
  //pattern to find all title="anything-inside-double-quote"
  $pattern = "#title=\"(.+)?\"#";

  foreach($breadcrumb as $k => $value){
        //replace with nothing so title won't print
   	$breadcrumb[$k] = preg_replace($pattern, '', $value);
  }

    //...some other code...
    
    $output .= '<div class="breadcrumb">' . implode(' » ', $breadcrumb) . '</div>';
    return $output;
  }
}

Thanks to regex ;-)
It took me some time, but nothing too long for accessibility...

Cheers.
