PHP 读取xml格式的字符串

我通过接口或得一个字符串：
<?xml version="1.0" encoding="utf-8" ?><responses code="200" msg="time: 0ms 971us"><response>法国</response><response>德国</response><response>中国</response><response>英国</response><response>泰国</response><response>美国</response><response>韩国</response><response>西兰公国</response><response>中非共和国</response><response>韩国丽水-韩国</response></responses>

但是应该是xml格式的，请问这种情况我应该怎么用Php读取出这里面的国家呢，不能用字符串替换。非常感谢，没分了，不好意思

Answer 1

$strXml='<?xml version="1.0" encoding="utf-8" ?><responses code="200" msg="time: 0ms 971us"><response>法国</response><response>德国</response><response>中国</response><response>英国</response><response>泰国</response><response>美国</response><response>韩国</response><response>西兰公国</response><response>中非共和国</response><response>韩国丽水-韩国</response></responses>';

$pos = strpos($strXml, 'xml');
if (!$pos) {
die("不是xml字符串！");
}
$obj=simplexml_load_string($strXml,'SimpleXMLElement', LIBXML_NOCDATA);
if(is_object($obj)){
$obj=get_object_vars($obj);
}

echo "<pre>";
print_r($obj);

另外记得文件一定要是utf-8编码，如果不是记得用iconv函数转一下。

$str = '<?xml version="1.0" encoding="utf-8" ?><responses code="200" msg="time: 0ms 971us"><response>法国</response><response>德国</response><response>中国</response><response>英国</response><response>泰国</response><response>美国</response><response>韩国</response><response>西兰公国</response><response>中非共和国</response><response>韩国丽水-韩国</response></responses>';
$postObj = simplexml_load_string($str, 'SimpleXMLElement', LIBXML_NOCDATA);
$arr = (array) $postObj->response;
