在 PHP 中解析 SOAP XML 提要

Question

我正在尝试从 OCTranspo Feed 中获取停止数据，以包含在家里的仪表板上。 OCTranspo API 允许您获取我已在 PHP 中成功运行的这些数据。

这是我收到的回复的副本：

  </soap:body>
</soap:envelope>

我需要在 PHP 中读取此响应，并让它输出“路线标签”、“路线编号”和“方向”，以及列出的三个行程中的每个行程的“调整计划时间”。

我可以正常加载响应，但无法让 PHP 页面解析 xml 提要。

这是我迄今为止尝试过的：

<?php
$mySoapResponse=file_get_contents('https://api.octranspo1.com/v1.2/GetNextTripsForStop?appID={ID}&apiKey={key}&routeNo=61&stopNo=9085');

echo $mySoapResponse;
?>
  <br>
  <hr>
  <br>
  <?php
// Loads the XML
$soap = simplexml_load_string($mySoapResponse);
$soap->registerXPathNamespace('ns1', 'http://raspberrypi.local/');

// Grabs the trips
$trips = $soap->xpath('/ns1:getnexttripsforstopresponse/ns1:getnexttripsforstopresult/ns1:error/ns1:route/ns1:routedirection/ns1:error/ns1:trips');
$label = $soap->xpath('/ns1:getnexttripsforstopresponse/ns1:getnexttripsforstopresult/ns1:stoplabel');
echo $label[0];
//$trips = $xml->children('soap', true)->Body->getnexttripsforstopresponse->getnexttripsforstopresult->error->route->routedirection->error->trips->trip;

// Take the posts and generate some markup
foreach ($trips as $trip)
{

        echo '
                <p>' . $trip->tripstarttime . '</p>
                <p>' . $trip->adjustedscheduletime . '</p>
                <p>' . $trip->bustype . '</p>
        ';
}

?>

好的，我现在知道了。基本上我只是放弃了 SOAP 处理并将其转换为 XML。关注这里的帖子：PHP - XML Response into Array 获取有关 PHP 中 XML 解析的一些技巧，瞧。

这是我的最终代码：

<html>

<head>
  <link rel="stylesheet" type="text/css" href="stylish.css">
</head>

<body>
  <?php
$mySoapResponse=file_get_contents('https://api.octranspo1.com/v1.2/GetNextTripsForStop?appID={AppID}&apiKey={KEY}$
$clean_xml = str_ireplace(['SOAP-ENV:', 'SOAP:','soap:'], '', $mySoapResponse);
$xml = simplexml_load_string($clean_xml);

//print_r($xml);


// Grabs the trips
$arrTrips = $xml->Body->GetNextTripsForStopResponse->GetNextTripsForStopResult->Route->RouteDirection->Trips->Trip;
//print_r($arrTrips);

//Grabs the route info
$routeInfo=$xml->Body->GetNextTripsForStopResponse->GetNextTripsForStopResult->Route->RouteDirection;

echo '<H1>Route ' . $routeInfo->RouteNo . ' ' . $routeInfo->RouteLabel . ' ' . $routeInfo->Direction . '</H1>';
echo '<h2>Next Trips</h2>';
// Take the posts and generate some markup
$i=1;
foreach ($arrTrips as $trip)
{

        echo '<p> ' . $i . '. Arrives in ' . $trip->AdjustedScheduleTime . ' minutes at ' . $trip->TripStartTime . '</p>';
        $i=$i+1;
}

?>
</body>
