操作方法：

require('class.xml.php');
$file = "data.xml";
$data = implode("",file($file)) or die("could not open XML input file");
$obj = new xml($data,"xml");


print $xml["hans"][0]->num_results[0];
for($i=0;$i<sizeof($xml["hans"]);$i++) {
print $xml["hans"][$i]->tag[0] . " ";
}

To print url attributes (if they exist):

print $xml["hans"][0]->attributes[0]["size"];
