If the domain, protocol and ports match, just use...

var links = $('iframe:first').contents()[0].links;

jsFiddle.

...or without jQuery...

var iframe = document.getElementsByTagName('iframe')[0],
    doc = iframe.contentDocument || iframe.contentWindow.document; 

var links = doc.links;

jsFiddle.

This takes advantage of the document.links property.

Assuming your iframe is on the same domain as your website, and has the id "my_iframe" and you have a div with the id "results", this should work for you:

$("#my_iframe").contents().find('a').each({
    $('#results').append($(this).attr('href') + '<br />');
});

Take a moment to read up on JQuery's .contents() function.
