篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了用PHP解析SOAP XML feed相关的知识，希望对你有一定的参考价值。
我正试图从OCTranspo Feed获取停止数据，以包含在家中的仪表板上。 OCTranspo API允许您获取此数据，我已成功运行php。
这是我得到的回复的副本：
<soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:body>
<getnexttripsforstopresponse xmlns="http://octranspo.com">
<getnexttripsforstopresult>
<stopno xmlns="http://tempuri.org/">9085</stopno>
<stoplabel xmlns="http://tempuri.org/">FERNBANK BRIGHTSIDE</stoplabel>
<error xmlns="http://tempuri.org/">
<route xmlns="http://tempuri.org/">

</route>

</getnexttripsforstopresult>
</getnexttripsforstopresponse>
</soap:body>
</soap:envelope>我需要在PHP中读取这个响应，并输出'route label'，'route number'和'direction'，以及每个列出的三个行程的'adjustedscheduletime'。
我可以加载响应很好，但我无法获取PHP页面来解析xml提要。
这是我到目前为止所尝试的：
<?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>
';
}
?>答案
好的，我现在知道了。基本上我只是将SOAP处理放在一起并将其转换为XML。点击这里的帖子：PHP - XML Response into Array获取有关PHP解析和瞧的XML解析的一些技巧。
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>
