Question

这里可以请求

   $data1 ='<?xml version="1.0" encoding="utf-8" ?> 
    <IDV>     
         <policy_start_date>21/12/2017</policy_start_date>     
         <vehicle_class_cd>45</vehicle_class_cd>     
         <RTOLocationCode>10416</RTOLocationCode>     
         <vehiclemodelcode>12474</vehiclemodelcode>     
         <manufacturer_code>27</manufacturer_code>     
         <purchaseregndate>21/12/2017</purchaseregndate>  
         <prev_policy_end_date>21/12/2016</prev_policy_end_date>
          <manufacturingyear>2014</manufacturingyear> 
    </IDV>';

   $url = "http://202.191.196.210/uat/onlineproducts/wscalculate/service.asmx/getIDV";

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POSTFIELDS,"str=" . $data1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
    $response = curl_exec($ch);
    curl_close($ch);
    echo $response;

在echo中我得到了以下回复

 <IDV>
 <exshowroomPrice>710570</exshowroomPrice>
 <idv_amount>675042</idv_amount>
 <idv_amount_min>607537</idv_amount_min>
 <idv_amount_max>776298</idv_amount_max>
 <exshowroomPrice_min>639513</exshowroomPrice_min>
 <exshowroomPrice_max>817156</exshowroomPrice_max>
 <outputmessage></outputmessage>
 </IDV>

现在如果我用

$xml = simplexml_load_string($response); 
print_r($xml);

我收到了以下回复

   SimpleXMLElement Object ( [0] => 710570675042607537776298639513817156 )

我想提取

      <exshowroomPrice>710570</exshowroomPrice>

如何提取那一个。请帮助我，我尝试了很多解决方案，但它没有工作。

Answer 1

只需使用SimpleXMLElement，

$xmlString = 
'<IDV>
 <exshowroomPrice>710570</exshowroomPrice>
 <idv_amount>675042</idv_amount>
 <idv_amount_min>607537</idv_amount_min>
 <idv_amount_max>776298</idv_amount_max>
 <exshowroomPrice_min>639513</exshowroomPrice_min>
 <exshowroomPrice_max>817156</exshowroomPrice_max>
 <outputmessage></outputmessage>
 </IDV>';


$xml = new SimpleXMLElement($xmlString);

echo $xml->exshowroomPrice;

Answer 2

如果使用PHP函数simplexml_load_string

正确创建对象

 $response = "
 <IDV>
 <exshowroomPrice>710570</exshowroomPrice>
 <idv_amount>675042</idv_amount>
 <idv_amount_min>607537</idv_amount_min>
 <idv_amount_max>776298</idv_amount_max>
 <exshowroomPrice_min>639513</exshowroomPrice_min>
 <exshowroomPrice_max>817156</exshowroomPrice_max>
 <outputmessage></outputmessage>
 </IDV>";

   $xml = simplexml_load_string($response);

然后创建的对象看起来像print_r($xml);

SimpleXMLElement Object
(
    [exshowroomPrice] => 710570
    [idv_amount] => 675042
    [idv_amount_min] => 607537
    [idv_amount_max] => 776298
    [exshowroomPrice_min] => 639513
    [exshowroomPrice_max] => 817156
    [outputmessage] => SimpleXMLElement Object
        (
        )
)

所以你只需要调用/ echo你需要的属性：

echo $xml->exshowroomPrice;
echo '<exshowroomPrice>' . $xml->exshowroomPrice . '</exshowroomPrice>';

将打印：

 710570  
 <exshowroomPrice>710570</exshowroomPrice>

首先你必须使用下面的代码检查xml中输出的格式是否正确，如果没有错误，则simplexml_load_string - 将XML字符串解释为对象。

    libxml_use_internal_errors(true);
    $doc = simplexml_load_string($response);
    $xml = explode("\n", $response);
    if (!$doc) {
       $errors = libxml_get_errors();
       foreach ($errors as $error) {
           echo display_xml_error($error, $xml);
       }
      libxml_clear_errors();
    } else { 
      $note = <<<XML $response XML;
      $xml = simplexml_load_string($note);
      $xml = (array) $xml;
      echo $xml['exshowroomPrice'];
      print_r($xml);
    }

你回来的XML看起来有点奇怪，但这并不罕见。它似乎将主要内容放在引号中，这并不重要，但它看起来很奇怪。更糟糕的是，它尝试使用的名称空间应该更像是一个正确的网址 - tempuri.org/应该是http://tempuri.org/或类似的名称。

无论如何 - 以下工作原理（尽管根据命名空间显示一些警告是相对的）。主要的是<string>元素具有默认命名空间，因此在加载数据时，需要考虑这一点。所以我所做的就是一旦我加载了它，我就会使用这个命名空间让孩子们（<IDV>等）。然后可以正常访问生成的SimpleXMLElement。

$response ='<string xmlns="tempuri.org/">; "
    <IDV>
        <exshowroomPrice>710570</exshowroomPrice>
        <idv_amount>675042</idv_amount>
        <idv_amount_min>607537</idv_amount_min>
        <idv_amount_max>776298</idv_amount_max>
        <exshowroomPrice_min>639513</exshowroomPrice_min>
        <exshowroomPrice_max>817156</exshowroomPrice_max>
        <outputmessage></outputmessage>
        </IDV>"
</string>';

$xml = simplexml_load_string($response, SimpleXMLElement::class,
        LIBXML_NOERROR );
$idv = $xml->children("tempuri.org/");
echo "exshowroomPrice ".$idv->IDV->exshowroomPrice.PHP_EOL;

其输出是......

exshowroomPrice 710570

更新：由于你回来的数据有标记编码（即它返回为<IDV>），你需要在将它传递给SimpleXML之前对其进行解码......

$response = html_entity_decode((string)$response);
$xml = simplexml_load_string($response, SimpleXMLElement::class,
        LIBXML_NOERROR );
$idv = $xml->children("http://tempuri.org/");
echo "exshowroomPrice ".$idv->IDV->exshowroomPrice.PHP_EOL;
