How to match double quotation marks with re in Python

inside the crawler, the whole html is sent down to download.
there is a js content

  $("-sharpjquery_jplayer_1").jPlayer({
    ready: function (event) {
        $(this).jPlayer("setMedia", {
            mp3: "http://audio.yixuela.com/czyy001/Starter Unit 1/Words and Expressions.mp3" //
        });
        duration=event.jPlayer.status.duration;

    },

now match the url address after mp3 directly. But no matter how re writes it, it can"t match. Depressed. Please ask. How to write this rule? Thank you
