Instead of using a regex you can try this which is clean and simple.

$('a').each(function(){
    $(this).text(this.protocol + "//" + (this.hostname || this.pathname));
});​

Note: If you want to set it only for set of anchors, then change the selector accordingly but the logic inside remains the same.
