Unsupported API – not available

seems that google api is out

google.com/ig/api?weather

if u dont, wrap simplexml_load_string in try/catch in php and use user error handling for xml:

try { 
    $data = simplexml_load_string(...);
catch( Exception $e ) {
    // error
    // do something with this $data
}

real example:

... method ...
$data = @file_get_contents($this->getApiUrl("", "Slovakia"));

if(!$data) {
    return false;
};

$data = iconv("ISO-8859-2", 'utf-8', $data);

// enable user error handling
libxml_use_internal_errors(true);

// load the document
$doc = new DOMDocument;

if (!$doc->load($data)) {
    libxml_clear_errors();
    return false;
}

try {
    $xmlData = new SimpleXMLElement($data);
} catch (Exception $e) {
    return false;
}

return true;
... end method ...

or simple:

libxml_use_internal_errors(true); 
try{
    $xmlObject = new SimpleXMLElement($wrongFormedText); 
} catch (Exception $e){ 
    return false;
}

1. always use error reporting 0!
2. do not dispaly ANY error on production!
2. wrap all your services for error handling
