wp_list_categories without <li>

Is there a way to use wp_list_categories function to generate the list of categories without

• element tags?

Or better, is there a way to get the categories as an array and the print it out the way I’d like? Something like that

	$miha_out = wp_list_categories('orderby=name&title_li=');
	eregi_replace('<li>', '', $miha_out);
	eregi_replace('</li>', '', $miha_out);
	echo $miha_out;

does not work as it outputs directly. Where is the wp_list_categories function defined anyway?

Thanks,

Miha.
