XmlPath选择前面/父属性

Question

给定以下XML片段：

<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>

当我需要提取所有ItineraryIds的列表时，基于具有MultiLegOutboundFlight="true“属性的子元素true

我如何编写一个XmlPath来实现这一点？我正在使用RestAssurred，并且正在进行实验，但发现很难在网上找到用于XmlPath语法的资源，所以我笨手笨脚地摸索着：

如果我这样做的话：

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，我有以下几点：

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

这将返回条件为真的所有假日的列表，但如何获取属性ItineraryID作为列表？

Answer 1

这是父节点的Xpath，

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

您需要添加的是将检索内部属性的方法。就像传递getAttribute('ItineraryId')一样

Answer 2

下面的片段可能对你有帮助。

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);
}
