Editing Breadcrumb Output

[ElwoodP]

I have some pages on a site that are split into multiple sections using <!--nextpage-->. I wanted to edit the genesis breadcrumb output to reflect which section of the page I was currently on.

I've successfully achieved this (with some very rudimentary php skills!) by editing the function get_page_crumb() found in breadcrumb.php class.

It works but obviously I don't want to leave edits in the core genesis file. How do I overwrite the function from my themes functions.php?

function get_page_crumb() {

global $wp_query, $page, $numpages;

if ( 'page' == $this->on_front && is_front_page() ) {
/** Don't do anything - we're on the front page and we've already dealt with that elsewhere */
$crumb = $this->get_home_crumb();
} else {
$post = $wp_query->get_queried_object();

/** If this is a top level Page, it's simple to output the breadcrumb */
if ( 0 == $post->post_parent ) {
$crumb = get_the_title();
} else {
if ( isset( $post->ancestors ) ) {
if ( is_array( $post->ancestors ) )
$ancestors = array_values( $post->ancestors );
else
$ancestors = array( $post->ancestors );
} else {
$ancestors = array( $post->post_parent );
}

$crumbs = array();
foreach ( $ancestors as $ancestor ) {
array_unshift(
$crumbs,
$this->get_breadcrumb_link(
get_permalink( $ancestor ),
sprintf( __( 'View %s', 'genesis' ), get_the_title( $ancestor ) ),
get_the_title( $ancestor )
)
);
}

/** Add the current page title */

if ($numpages > 1) {
$crumbs[] = '<a href="' . get_permalink( $post ) . '">' . get_the_title( $post->ID ) . '</a> » Part ' . $page;
} else {
$crumbs[] = get_the_title( $post->ID );
}

$crumb = join( $this->args['sep'], $crumbs );
}
}

return apply_filters( 'genesis_page_crumb', $crumb, $this->args );

}
}

Thanks Antiac I'm not sure that helps. As far as I can work out I can use filters to change various static parts of the breadcrumb but I can't use filters to achieve what I'm after?
