Let's take this markup which describes

    Two places 
    with the name "Tsujido" and "Meguro
    and their associated longitude and latitude.

    <ul vocab="http://schema.org/">
        <li typeof="Place">
            <span property="name">Tsujido</span>
            <div property="geo"
                 <meta property="latitude" content="35.336833"/>
                 <meta property="longitude" content="139.447083"/>
        <li typeof="Place">
            <span property="name">Meguro</span>
            <div property="geo"
                 <meta property="latitude" content="35.633983"/>
                 <meta property="longitude" content="139.71600"/>

I would love to be able to do something such as 

    "for each place return the longitude"

    var places = document.getItems('http://schema.org/Place');
    for (var i = places.length - 1; i >= 0; i--) {
       longitude = places[i].properties['longitude']

And then in the console:
