Parsing google calendar XML feed

Question

I've got XML feed from public google calendar. Looks like this:

<?xml version='1.0' encoding='UTF-8'?>
    <feed xmlns='................' xmlns:gd='http://schemas.google.com/g/2005'>
        <id>http://www.google.com/calendar/feeds/........./public/full</id>
        <updated>2009-08-24T10:57:00.000Z</updated>
        <category scheme='http://schemas.google.com/g/2005#kind' term='http://schemas.google.com/g/2005#event'/>
            <title type='text'>Sports Events</title>
    .....
        <entry>
            <id>...........</id>
            <published>2009-08-14T00:29:58.000Z</published>
            <updated>2009-08-14T00:29:58.000Z</updated>
            <category scheme='http://schemas.google.com/g/2005#kind' term='http://schemas.google.com/g/2005#event'/>
..............
            <georss:where>
                <gml:Point>
                    <gml:pos>11.111111 -22.22222</gml:pos>
                </gml:Point>
            </georss:where>
            <gd:eventStatus value='http://schemas.google.com/g/2005#event.confirmed'/>
            <gd:transparency value='http://schemas.google.com/g/2005#event.transparent'/>
            <gCal:uid value='[email protected]'/>
            <gCal:sequence value='0'/>
            <gd:when startTime='2009-10-03' endTime='2009-10-04'/>

.............

Now to PHP:

$calendar = simplexml_load_file('http://my.feed.com');
foreach ($calendar->entry as $item) {
    //here I get the whole <entry> node
    $gd = $item->children('http://schemas.google.com/g/2005');
    // now in $gd I have all nodes like <gd:XXXXX>
}

The problem is how to get value from here?

<gml:pos>11.111111 -22.22222</gml:pos>

Its not present in my $gd variable, how to get this node?

I highly recommend using this library: https://github.com/collegeman/coreylib. It'll make everything from start to finish mind-numbingly easy.
