php parse xml from url - php parse xml from url

http://api.hostip.info/?ip=87.14.94.152

从这个链接（xml），我试图检索countryName和countryAbbrev，如下所示：

$url = 'http://api.hostip.info/?ip=87.14.94.152';
$xml = simplexml_load_file($url) or die("feed not loading");
$Country = $xml->gml['featureMember']->Hostip->countryName;
echo $Country;
echo 'BREAK HTML';
echo "-----";
echo "// "; var_dump($xml); echo " //";

但是$Country是空白的，你知道吗？

提前感谢

尝试这不是一个答案，而是另一种方法：

$data = file_get_contents('http://api.hostip.info/get_html.php?ip=87.14.94.152&position=true');
$arrayofdata = explode("'n", $data);
$country = explode(":", $arrayofdata[0]);
$count = explode(" ", $country[1]);
echo "Country Name: ".$count[1]."</br>";    //Prints ITALY
echo "Country Abbv: ".trim($count[2],"()"); //Prints IT

position=true url部分，这只是为了防止您想要检索坐标。

干杯；）

试试这个：

$url = 'http://api.hostip.info/?ip=87.14.94.152';
$xml = simplexml_load_file($url) or die("feed not loading");
$fm=$xml->xpath('//gml:featureMember');
print_r($fm[0]->Hostip->countryName);

制作xml的本地副本，它就可以工作了。刚刚测试了这个并得到了数据：

$url = 'http://api.hostip.info/?ip=87.14.94.152';
$data = file_get_contents($url);
$xml = simplexml_load_file($data) or die("feed not loading");

countryName节点嵌套在更深层次。可以使用children()方法访问带有冒号的属性。以下是如何获得国家名称：

$countryName = (string) $xml->children('gml', true)
                            ->featureMember->children('', true)
                                ->Hostip->countryName; // => ITALY

您还可以使用XPath表达式来检索国家/地区名称。这更容易：

$hostip = $xml->xpath('//Hostip'); 
$countryName = $hostip[0]->countryName;       // => ITALY
$countryAbbrev = $hostip[0]->countryAbbrev;   // => IT

     protected function getCountryNameFromIP()
     {
        $ip  = $_SERVER['REMOTE_ADDR'];
        $opts = array(
        'http'=>array(
        'method'=>"GET",
        'header'=>"Accept-language: en'r'n" .
                  "Cookie: foo=bar'r'n"
           )
        );
        $context = stream_context_create($opts);
        $answerIP = @file_get_contents("http://api.ipinfodb.com/v3/ip-country/?key=4b585e37503a519a408dc17878e6ec04fa963e1b946c567722538d9431c2d5cb&format=xml&ip=$ip" ,false,$context);
        if(isset($answerIP) && $answerIP !="")
        {
            $theResJ            =   simplexml_load_string($answerIP);
            $last_login_ip_cn   =   $theResJ->countryName;

            /**
            *   $last_login_ip_cc   =   $theResJ->countryCode;
            *   $last_login_ip_rc   =   $theResJ->regionCode;
            *   $last_login_ip_rn   =   $theResJ->regionName;
            *   $last_login_ip_cp   =   $theResJ->cityName;
            *   $last_login_ip_lat  =   $theResJ->latitude;
            *   $last_login_ip_lng  =   $theResJ->longitude;
            *   $last_login_zip_code=   $theResJ->zipCode;
            */
        }
        else
        {
            $last_login_ip_cn   =   "";
            /**
            *   $last_login_ip_cc   =   "";
            *   $last_login_ip_rc   =   "";
            *   $last_login_ip_rn   =   "";
            *   $last_login_ip_cp   =   "";
            * $last_login_ip_lat    =   "";
            *   $last_login_ip_lng  =   "";
            *   $last_login_zip_code=   "";
            */
        }
        return $last_login_ip_cn;
       }
I hope it helps you

我同意。我试了两个答案，结果都很好。这是我刚刚运行的测试代码：

<?php
$url = 'http://api.hostip.info/?ip=87.14.94.152';
// $data = file_get_contents($url);
$xml = simplexml_load_file($url) or die("feed not loading");
// $Country = $xml->gml['featureMember']->Hostip->countryName;
// echo $Country;
echo 'BREAK HTML';
echo "-----";
echo "// "; var_dump($xml); echo " //<br/>";
?><br/><?php
var_dump($xml->gml);
?><br/><?php
print_r($xml);
?><br/><?php
var_dump((string) $xml->gml->featureMember->Hostip->countryName);
?><br/><?php
echo $xml->gml['featureMember']->Hostip->countryName;
$Country = (string) $xml->children('gml', true)
                            ->featureMember->children('', true)
                                ->Hostip->countryName; // => ITALY
echo $Country;
$fm=$xml->xpath('//gml:featureMember');
print_r($fm[0]->Hostip->countryName);

这是结果输出：

BREAK HTML-----/object（SimpleXMLElement）#1（1）{["@attributes"]=>数组（1）｛["version"]=>字符串（5）"1.0.1"｝//

对象（SimpleXMLElement）#2（0）｛｝SimpleXMLElement对象（[@attributes]=>数组（[version]=>1.0.1））字符串（0）"ITALYSimpleXMLElement对象（[0]=>ITALY）
