XML文件解析

XML源码

判断Xml文件中某一个节点是否存在子节点：

首先要获取到节点的document，
Element root = document.getRootElement();
Element HotelGeoList = root.element(“HotelGeoList”);
for(Iterator iteratorHotelGeo = HotelGeoList.elementIterator(“HotelGeo”);iteratorHotelGeo.hasNext()????{
Element HotelGeo = (Element) iteratorHotelGeo.next();
Document d = HotelGeo.getDocument();
if(d.selectNodes("//*").size()>0){
System.out.println(“存在子节点”);
}

节点下不同子节点内容的解析

Element District = HotelGeo.element(“Districts”);
if(District!=null){ //判断是否存在district的子节点
for(Iterator iteratorLocation = District.elementIterator(“Location”);iteratorLocation .hasNext()????{
District district = new District();
Element Locations = (Element) iteratorLocation.next();
district.setDistrictName(Locations.attributeValue(“Name”));
district.setDistrictId(Locations.attributeValue(“Id”));
district.setCity(city);
district = districtService.createDistrict(district);
System.out.println("---------------"+district.getDistrictId()+"–"+district.getDistrictName());
}
}

Element CommericalLocation = HotelGeo.element(“CommericalLocations”);
if(CommericalLocation!=null){//判断是否存在CommericalLocation子节点

    for(Iterator iteratorLocation  = CommericalLocation.elementIterator("Location");iteratorLocation .hasNext();){
        CommericalLocation commericalLocation = new CommericalLocation();
        Element Locations = (Element) iteratorLocation.next();
        commericalLocation.setCommericalLocationName(Locations.attributeValue("Name"));
        commericalLocation.setCommericalLocationId(Locations.attributeValue("Id"));
        commericalLocation.setCity(city);
        commericalLocation = commericalLocationService.createCommericalLocation(commericalLocation);
        System.out.println("---------------"+commericalLocation.getCommericalLocationId()+"-----"+commericalLocation.getCommericalLocationName());
    }
  }

Element LandmarkLocation = HotelGeo.element(“LandmarkLocations”);
if(LandmarkLocation!=null){//判断是否存在LandmarkLocation子节点

     for(Iterator iteratorLocation  = LandmarkLocation.elementIterator("Location");iteratorLocation .hasNext();){
        LandmarkLocation landmarkLocation = new LandmarkLocation();
        Element Locations = (Element) iteratorLocation.next();
        landmarkLocation.setLandmarkLocationName(Locations.attributeValue("Name"));
        landmarkLocation.setLandmarkLocationId(Locations.attributeValue("Id"));
        landmarkLocation.setCity(city);
        landmarkLocation = landmarkLocationService.createLandmarkLocation(landmarkLocation);
        System.out.println("---------------"+landmarkLocation.getLandmarkLocationId()+"---"+landmarkLocation.getLandmarkLocationName());
     }
}
