Android XML解析问题（多个标记）

我正在使用DOM解析器分析XML，但我似乎遇到了一个问题，我的

XML

数据结构如下：

    <Bookings>
  <BookingNo>12345678</BookingNo>
  <Pickup>
    <AddressLine>Line 1</AddressLine>
    <AddressLine>Line 2</AddressLine>
    <AddressLine>Line 3</AddressLine>
    <AddressLine>Line 4</AddressLine>
    <AddressLine>Line 5</AddressLine>
    <Postcode>
      <PostcodeOut>pstOut</PostcodeOut>
      <PostcodeIn>pstIn</PostcodeIn>
    </Postcode>
    <AddressCoords>
      <Latitude>1.12345670</Latitude>
      <Longitude>-1.1234567890</Longitude>
    </AddressCoords>
  </Pickup>
  <Destination>
    <AddressLine>Line 1</AddressLine>
    <AddressLine>Line 2</AddressLine>
    <AddressLine>Line 3</AddressLine>
    <Postcode>
      <PostcodeOut>pstOut</PostcodeOut>
      <PostcodeIn>pstIn</PostcodeIn>
    </Postcode>
    <AddressCoords>
      <Latitude>1.1234567890</Latitude>
      <Longitude>-1.1234567890</Longitude>
    </AddressCoords>
  </Destination>
  <PickupTime>DateTime</PickupTime>
  <DestinationTime>DateTime</DestinationTime>
  <VehicleType>Car</VehicleType>
  <NumberOfPassengers>1</NumberOfPassengers>
  <Passengers>
    <PassengerName>Name</PassengerName>
    <PassengerContactNo>123456</PassengerContactNo>
  </Passengers>
   <Mileage>2</Mileage>
</Bookings>

我的主要活动中的代码是：

XMLParser parser = new XMLParser();
                    Document doc = parser.getDomElement(xml); // getting DOM
                    references = new ArrayList<String>();
                    NodeList nl = doc.getElementsByTagName("Bookings");
                    NodeList nlpickup = doc.getElementsByTagName("Pickup");
                    NodeList nldestination = doc
                            .getElementsByTagName("Destination");
                    AddressData = new StringBuilder();

                    // looping through all item nodes <item>
                    for (int i = 0; i < nl.getLength(); i++) {
                        HashMap<String, String> map = new HashMap<String, String>();

                        Element e = (Element) nl.item(i);
                        resultCode = parser.getValue(e, "BookingNo");
                        Pickup = parser.getValue(e, "Pickup");
                        DateTime = parser.getValue(e, "PickupTime");

                        Element etwo = (Element) nlpickup.item(i);

                        PAddressTwo = parser.getValue(etwo, "AddressLine");

                        // System.out.println("/// "+ AddressData);
                        // System.out.println("/////"+parser.getValue(etwo,
                        // "AddressLine"));

                        PPostIn = parser.getValue(etwo, "PostcodeOut");
                        PPostOut = parser.getValue(etwo, "PostcodeIn");

                        Element ethree = (Element) nldestination.item(i);
                        DAddressOne = parser.getValue(ethree, "AddressLine");
                        DPostIn = parser.getValue(ethree, "PostcodeOut");
                        DPostOut = parser.getValue(ethree, "PostcodeIn");

                        splitDate();

                        map.put("BookNo", resultCode);
                        map.put("Datetime", TimeFinal + " on " + DateFinal);
                        map.put("PickupAddress", PAddressTwo + " " + PPostIn
                                + " " + PPostOut);
                        map.put("DestinationAddress", DAddressOne + " "
                                + DPostIn + " " + DPostOut);

                        references.add(resultCode);

                        mylist.add(map);
                    }

                    adapter = new SimpleAdapter(
                            MyJourney.this,
                            mylist,
                            R.layout.myjourneys_item,
                            new String[] { "BookNo", "Datetime",
                                    "PickupAddress", "DestinationAddress" },
                            new int[] { R.id.journeysRefText,
                                    R.id.journeysDateText,
                                    R.id.journeysFromText, R.id.journeysToText });

                }

我哪里做错了

我知道有一种叫做SAX解析器的东西，但我可以找到一个与我正在寻找的东西相匹配的示例。

试试这个：

    Element element = document.getDocumentElement();

    // For Pickup
    NodeList nodeListPickup = element.getElementsByTagName("Pickup");
    for (int i = 0; i < nodeListPickup.getLength(); i++) {
        Node node = nodeListPickup.item(i);
        NodeList pickUp = node.getChildNodes();

        for (int j = 0; j < pickUp.getLength(); j++) {

            Node nodePickup = pickUp.item(j);
            String name = nodePickup.getNodeName();

            if(name.equals("AddressLine")){ 
                System.out.println("Pickup > AddressLine > " +nodePickup.getFirstChild().getNodeValue());
            }       
        }
    }

    // For Destination
    NodeList nodeListDestination = element.getElementsByTagName("Destination");
    for (int i = 0; i < nodeListDestination.getLength(); i++) {
        Node node = nodeListDestination.item(i);
        NodeList destination = node.getChildNodes();                
        for (int j = 0; j < destination.getLength(); j++) {

            Node nodeDestination = destination.item(j);     
            String name = nodeDestination.getNodeName();

            if(name.equals("AddressLine")){                 
                System.out.println("Destination > AddressLine > " +nodeDestination.getFirstChild().getNodeValue());
            }       
        }
    }

Element=document.getDocumentElement（）；
//接送
NodeList nodeListPickup=element.getElementsByTagName（“拾取”）；
对于（int i=0；i地址行>”+nodePickup.getFirstChild（）.getNodeValue（））；
}       
}
}
//目的地
NodeList nodeListDestination=element.getElementsByTagName（“目的地”）；
对于（int i=0；i地址行>”+nodeDestination.getFirstChild（）.getNodeValue（））；
}       
}
}

我已经为皮卡和目的地创建了不同的节点列表，您可以在这两个节点中获得其余的内部标记，目前我只显示AddressLine。让我知道这是否有帮助。

这确实很有帮助，现在只需要弄清楚如何正确地构造它lol

    Element element = document.getDocumentElement();

    // For Pickup
    NodeList nodeListPickup = element.getElementsByTagName("Pickup");
    for (int i = 0; i < nodeListPickup.getLength(); i++) {
        Node node = nodeListPickup.item(i);
        NodeList pickUp = node.getChildNodes();

        for (int j = 0; j < pickUp.getLength(); j++) {

            Node nodePickup = pickUp.item(j);
            String name = nodePickup.getNodeName();

            if(name.equals("AddressLine")){ 
                System.out.println("Pickup > AddressLine > " +nodePickup.getFirstChild().getNodeValue());
            }       
        }
    }

    // For Destination
    NodeList nodeListDestination = element.getElementsByTagName("Destination");
    for (int i = 0; i < nodeListDestination.getLength(); i++) {
        Node node = nodeListDestination.item(i);
        NodeList destination = node.getChildNodes();                
        for (int j = 0; j < destination.getLength(); j++) {

            Node nodeDestination = destination.item(j);     
            String name = nodeDestination.getNodeName();

            if(name.equals("AddressLine")){                 
                System.out.println("Destination > AddressLine > " +nodeDestination.getFirstChild().getNodeValue());
            }       
        }
    }
