Extracting Certain XML Elements with PHP SimpleXML

I am having some problems parsing this piece of XML using SimpleXML. There is always only one Series element, and a variable number of Episode elements beneath. I want to parse XML so I can store the Series data in one table, and all the Episode data in another table.

XML:

<Data>
    <Series>
        <id>80348</id>
        <Genre>|Action and Adventure|Comedy|Drama|</Genre>
        <IMDB_ID>tt0934814</IMDB_ID>
        <SeriesID>68724</SeriesID>
        <SeriesName>Chuck</SeriesName>
        <banner>graphical/80348-g.jpg</banner>
    </Se开发者_如何转开发ries>
    <Episode>
        <id>935481</id>
        <Director>Robert Duncan McNeill</Director>
        <EpisodeName>Chuck Versus the Third Dimension 2D</EpisodeName>
        <EpisodeNumber>1</EpisodeNumber>
        <seasonid>27984</seasonid>
        <seriesid>80348</seriesid>
    </Episode>
    <Episode>
        <id>935483</id>
        <Director>Robert Duncan McNeill</Director>
        <EpisodeName>Buy More #15: Employee Health</EpisodeName>
        <EpisodeNumber>2</EpisodeNumber>
        <seasonid>27984</seasonid>
        <seriesid>80348</seriesid>
    </Episode>
</Data>

When I attempt to access just the first Series element and child nodes, or iterate through the Episode elements only it does not work. I have also tried to use DOMDocument with SimpleXML, but could not get that to work at all.

PHP Code:

<?php
    if(file_exists('en.xml'))
    {
        $data = simplexml_load_file('en.xml');
        foreach($data as $series)
        {
            echo 'id: <br />' . $series->id;
            echo 'imdb: <br />' . $series->IMDB_ID;
        }
    }
?>

Output:

id:80348
imdb:tt0934814
id:935481
imdb:
id:1534641
imdb:

I just discovered the stupid mistake I was making.

The PHP code should have been like this:

<?php
    if(file_exists('en.xml'))
    {
        $data = simplexml_load_file('en.xml');
        foreach($data->Series as $series)
        {
            echo 'id: <br />' . $series->id;
            echo 'imdb: <br />' . $series->IMDB_ID;
        }
    }
?>

The first time I tried this (and it did not work) I was using;

$data->series as $series

So it was a capital 'S' that was the issue.
