Question

给出以下XML代码段：

<Holiday ItineraryId="123456789" Country="ES" NumberOfNights="7" LeadInPricePerPassenger="447.3" FlightOnly="true" OneWayOnly="false" Currency="GBP" BookingChannel="WEB" PassengerIdRequired="false" PassengerIdMandatory="false" NationalityRequired="false" NationalityMandatory="false">
    <Flight OriginAirport="LGW" DestinationAirport="ALC" MultiLegOutboundFlight="true">
          <OutboundSubSegments DeparturePoint="LGW" DepartureDate="20180802" DepartureTime="0920" ArrivalPoint="OSL" ArrivalDate="20180802" ArrivalTime="1225" OperatingCarrier="DY" OperatedBy="Super Air Shuttle" FlightNumber="HY637" OriginAirportName="London Gatwick" DestinationAirportName="Oslo" />
   </Flight>
</Holiday>

<Holiday ItineraryId="9283873737" Country="ES" NumberOfNights="7" LeadInPricePerPassenger="447.3" FlightOnly="true" OneWayOnly="false" Currency="GBP" BookingChannel="WEB" PassengerIdRequired="false" PassengerIdMandatory="false" NationalityRequired="false" NationalityMandatory="false">
    <Flight OriginAirport="LGW" DestinationAirport="ALC" MultiLegOutboundFlight="true">
          <OutboundSubSegments DeparturePoint="LGW" DepartureDate="20180802" DepartureTime="0920" ArrivalPoint="OSL" ArrivalDate="20180802" ArrivalTime="1225" OperatingCarrier="DY" OperatedBy="Super Air Shuttle" FlightNumber="HY637" OriginAirportName="London Gatwick" DestinationAirportName="Oslo" />
   </Flight>
</Holiday>

<Holiday ItineraryId="894847463" Country="ES" NumberOfNights="7" LeadInPricePerPassenger="447.3" FlightOnly="true" OneWayOnly="false" Currency="GBP" BookingChannel="WEB" PassengerIdRequired="false" PassengerIdMandatory="false" NationalityRequired="false" NationalityMandatory="false">
    <Flight OriginAirport="LGW" DestinationAirport="ALC" MultiLegOutboundFlight="true">
          <OutboundSubSegments DeparturePoint="LGW" DepartureDate="20180802" DepartureTime="0920" ArrivalPoint="OSL" ArrivalDate="20180802" ArrivalTime="1225" OperatingCarrier="DY" OperatedBy="Super Air Shuttle" FlightNumber="HY637" OriginAirportName="London Gatwick" DestinationAirportName="Oslo" />
   </Flight>
</Holiday>

当我需要基于具有MultiLegOutboundFlight =“ true”属性的子元素Flight提取 all 所有ItineraryIds列表时，

如何编写XmlPath来实现此目的？我正在使用RestAssurred并正在尝试，但是发现很难在线查找XmlPath语法的资源，因此摸不着头脑：

如果我执行以下操作：

public List<String> getMultiLegFlightItineraryIdList() {
    XmlPath xmlPath = new XmlPath(response.asString()); if(xmlPath.getNode("Holiday.Flight").getAttribute("MultiLegOutboundFlight").equals("true")) {
        String itineraryId = xmlPath.getNode("Holiday").getAttribute("ItineraryId");
        System.out.println(itineraryId);
    }
    return itineraryIDList;
}

然后我收到以下错误：

[Fatal Error] :2:802: The markup in the document following the root element must be well-formed.
ERROR:  'The markup in the document following the root element must be well-formed.'

java.lang.IllegalArgumentException: Failed to convert XML to Java Object. If 
you're trying convert to a list then use the getList method instead.

最初我有以下内容：

allMultiLegPackages = response.xmlPath().getList("Holiday.Flight.findAll{it.@MultiLegOutboundFlight=='true'}//parent::Holiday");

这将返回条件为true的所有Holidays的列表，但是如何获取ItineraryID的属性作为列表？

Answer 1

这是您的父节点的Xpath

//flight[@multilegoutboundflight='true']//parent::holiday

您需要额外添加的是将检索内部属性的方法。就像通过getAttribute('ItineraryId')

Answer 2

下面的代码段可能会对您有所帮助。

String itineraryId = "";
XmlPath xmlpath = new XmlPath(responseXML);
if(xmlpath.getNode("Holiday").getNode("Flight").getAttribute("MultiLegOutboundFlight").equals("true")) {
    itineraryId = xmlpath.getNode("Holiday").getAttribute("ItineraryId");
    System.out.println("Itinerary ID ::: "+itineraryId);
}

导入：

import com.jayway.restassured.path.xml.XmlPath;

XmlPath选择前面/父属性
