我必須解析上面的xml響應。請幫助我。

我正在使用下面的代碼，但它使我錯誤代碼，並沒有獲得變量中的所有值。

foreach ($data->FlightOption as $FlightOption) { 
    printf(
     $FlightOption["Flight"]->ArrivalDateTime 
     /*$FlightOption->FareClass, 
     $FlightOption->Airline*/ 
    ); 
} 

Answer 1

假設你的XML是這樣的：

<?xml version="1.0"?> 
<data> 
    <FlightOption> 
     <Flight ArrivalDateTime="2014-07-05T15:00:00.000" DepartureDateTime="2014-07-05T13:00:00.000" EquipmentCode="321" FlightNumber="677"> 
      <Airline AirlineCode="AI" IATACode="AI" ICAOCode="AIC" Name="Air India" /> 
      <ArrivalAirport AirportCode="DEL" IATACode="DEL" ICAOCode="VIDP" Name="Indira Gandhi International Airport" /> 
      <Cabin Code="C" Name="Coach"> 
       <FareClass Code="Y" Name="ECONOMY" NumOfAvailableSeats="9" /> 
      </Cabin> 
      <Cabin Code="B" Name="Business"> 
       <FareClass Code="C" Name="BUSINESS" NumOfAvailableSeats="4" /> 
      </Cabin> 
     </Flight> 
    </FlightOption> 
</data> 

它看起來像你的問題是，目前在各FlightOption元素多FareClass元素。這將需要在第一個循環內嵌套循環。下面的代碼：

<?php 

$data = simplexml_load_file("data.xml"); 

foreach($data->FlightOption as $FlightOption) 
{ 
    $arrivalDateTime = $FlightOption->Flight["ArrivalDateTime"]; 
    $airline = $FlightOption->Flight->Airline["Name"]; 

    foreach($FlightOption->Flight->Cabin as $Cabin) 
    { 
     print($arrivalDateTime); 
     print("/"); 
     print($Cabin->FareClass["Name"]); 
     print("/"); 
     print($airline); 

     print("<br/><br/>"); 
    } 

    print("<br/><br/>"); 
} 

?> 

將產生以下的輸出：

2014-07-05T15:00:00.000/ECONOMY/Air India 

2014-07-05T15:00:00.000/BUSINESS/Air India
