 文件名：test.xml

方法一：读取文件到一个字符串，通过解析字符串：

$url  = "http://localhost/test/test.xml";
$xmlString=file_get_contents($url);
$xml_array=simplexml_load_string($xmlString); 
var_dump($xml_array);

	$state = $xml_array->ADDRESS_value->value[4]['state'];
 	$city = $xml_array->ADDRESS_value->value[5]['city'];
	$address =$xml_array->ADDRESS_value->value[6]['address']; 
	$state = iconv("UTF-8","EUC-JP",$state);
	$city = iconv("UTF-8","EUC-JP",$city);
	$address =iconv("UTF-8","EUC-JP",$address);
	echo '$state='.$state.'<br>';
	echo '$city='.$city.'<br>';
	echo '$address='.$address.'<br>';

 方法二：直接解析xml文件

$xml = simplexml_load_file（"http://localhost/test/test.xml"）

 print_r($xml);
