    Extracting data from xml file

    I'm trying to include a weather forecast into my webpage using php - the xmlhttprequest returns an xml file. Below is the code I've used but I just get a blank page, can someone help? This is my first attempt at using xmlhttprequest and xml files so forgive all errors.

    Code:
    <?php
    include 'weather.php';
    $xml= new SimpleXMLElement($xmlstr);
    $weatherData = $xml->xpath('date/tempMaxC/tempMinC/tempMaxF/tempMinF/weatherDesc');
    while(list(, $node) = each($weatherData)) {
    echo '/date/tempMaxC/tempMinC/tempMaxF/tempMinF/weatherDesc ',$node,"\n";
    }
    ?>
    weather.php is a file I've set up to learn this stuff and contains the following data which is sent by the weather service I'm using:
    Code:
    <?php
    $xmlstr = <<<XML
    <?xml version='1.0' standalone='yes'?>
    <data><request><type>Zipcode</type><query>80487</query></request><current_condition><observation_time>10:14 AM</observation_time><temp_C>-2</temp_C><temp_F>29</temp_F><weatherCode>122</weatherCode><weatherIconUrl>http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0004_black_low_cloud.png</weatherIconUrl><weatherDesc>Overcast </weatherDesc><windspeedMiles>16</windspeedMiles><windspeedKmph>26</windspeedKmph><winddirDegree>240</winddirDegree><winddir16Point>WSW</winddir16Point><precipMM>4.3</precipMM><humidity>81</humidity><visibility>16</visibility><pressure>1001</pressure><cloudcover>100</cloudcover></current_condition>

    Here's what I've used which gets what I need.
    Code:
    <?php
    include 'weather.php';
    $data= new SimpleXMLElement($xmlstr);
    foreach ($data->weather as $weather) {
    
    	$date = (string) $weather->date;
    	$maxC = (int) $weather->tempMaxC;
    	$minC = (int) $weather->tempMinC;
    	$maxF = (int) $weather->tempMaxF;
    	$minF = (int) $weather->tempMinF;
    	$desc = (string) $weather->weatherDesc;
    	$iconUrl = (string) $weather->weatherIconUrl;
    
    echo '<ul id="forecast"> <li class="fcdate">' . $date .  '</li><li>' .$maxC . '</li><li>' .
    $minC . '</li><li>' . $maxF . '</li><li>' . $minF . '</li><li>' . $desc . '</li><li>' . $iconUrl . '</li>
    </ul>';
    }
    ?>
