dom4j解析Xml，dom4j解析带命名空间的Xml内容，dom4j解析xml为实体类

Posted 2020-10-04

首先引入maven：

        <dependency>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
            <version>1.6.1</version>
        </dependency>

        <dependency>
            <groupId>jaxen</groupId>
            <artifactId>jaxen</artifactId>
            <version>1.1.6</version>
        </dependency>            

 

要解析的 xml 内容：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmladnsoaper.org/soaper/envel/">
    <SOAP-ENV:Header/>
    <SOAP-ENV:Body>
        <TrackReply xmlns="http://fedde.com/ws/track/v14">
            <HighestSeverity>SUCCESS</HighestSeverity>
            <CompletedTrackDetails>
                <HighestSeverity>SUCCESS</HighestSeverity>
                <Notifications>
                    <Severity>SUCCESS</Severity>

                <MoreData>false</MoreData>
                <TrackDetailsCount>0</TrackDetailsCount>
                <TrackDetails>

java 代码解析带命名空间内的Events标签内容：

private List<Event> getFeddeDetails(String body) {
        List<Event> eventList = new ArrayList<Event>();
        Document document;
        try {
            Map<String, String> nameSpaceMap = new HashMap<>();
            nameSpaceMap.put("track", "http://Fedde.com/waws11/track12/v14");
            document = DocumentHelper.parseText(body);
            Element element = document.getRootElement();
            XPath xPath = element.createXPath("//track:Events");
            xPath.setNamespaceURIs(nameSpaceMap);
            List<Element> EventsList = xPath.selectNodes(element);
            Iterator<Element> EventsIter = EventsList.iterator();
            while (EventsIter.hasNext()) {
                Element eventElt = EventsIter.next();
                Event event = new Event();
                Iterator<Element> subIter = eventElt.elements().iterator();
                while (subIter.hasNext()) {
                    Element subElt = subIter.next();
                    if ("Timestamp".equals(subElt.getName())) {
                        event = dateFormat(subElt.getStringValue(), event);
                    } else if ("EventDescription".equals(subElt.getName())) {
                        event.setDescription(subElt.getStringValue());
                    } else if ("Address".equals(subElt.getName())) {
                        Element cityElt = subElt.element("City");
                        event.setCity(cityElt.getStringValue());
                        Element CountryElt = subElt.element("CountryName");
                        event.setCountry(CountryElt.getStringValue());
                    }
                }
                eventList.add(event);
            }
            for (Event event : eventList) {
                System.out.println(event);
            }

        } catch (DocumentException | ParseException e) {
            e.printStackTrace();
        }
        return eventList;
    }

输出结果：

Event [city=KWUN TONG, country=Hong Kong, date=2017-08-07, time=12:10, description=Left FedEx origin facility]
Event [city=KWUN TONG, country=Hong Kong, date=2017-08-07, time=09:01, description=Picked up]
