我必须解析上面的xml响应。请帮助我。

我正在使用下面的代码，但它会给我错误代码并且不会在变量中获取所有值。

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

Answer 1

假设您的xml如下所示：

<?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>

看起来您的问题是每个FareClass元素中有多个FlightOption元素。这将需要在第一个循环内部嵌套循环。以下代码：

<?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/>");
}

?>

将产生以下输出：

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

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