解析调用接口内容和构建接口请求xml

如果接口返回值为java.io.InputStream类型

import org.dom4j.Document;  
import org.dom4j.DocumentHelper;  
import org.dom4j.Element;  
import org.dom4j.Node;  
import org.dom4j.io.SAXReader;

public HotelListResult parseResult(InputStream input) \{  
HotelListResult hotelResult = new HotelListResult();  
SAXReader saxReader = new SAXReader();  
try \{  
Document doc = saxReader.read(input);

Node countNode= doc.selectSingleNode("/TransmitData/hotelList/hotel-response/count");

if (countNode != null )\{

int count = NumberUtils.toInt(countNode.getText());

其他基本类型内容都可以使用这种方法解析，如果解析的为集合，并且每个值都为对象，则可以使用下边方法解析

List<?> hotelBaseListNode = doc.selectNodes("/TransmitData/hotelList/hotel-response/hotelbase");

if (hotelBaseListNode != null && hotelBaseListNode.size() > 0)\{

for (Iterator it = hotelBaseListNode.iterator(); it.hasNext();) \{  
Element hotelBaseNode = (Element) it.next();  
String hotelid = HotelApiUtil.getNodeText(hotelBaseNode.selectSingleNode("hotelid"));  
String hotelName = HotelApiUtil.getNodeText(hotelBaseNode.selectSingleNode("hotelName"));

.......

如果接口返回值为String类型

import org.dom4j.DocumentHelper;

public static HotelListResult parseResult(String xml) \{

try \{  
Document doc = DocumentHelper.parseText(xml);

Node countNode= doc.selectSingleNode("/TransmitData/hotelList/hotel-response/count");

if(countNode!=null )\{

int count = NumberUtils.toInt(countNode.getText());

如果解析的为集合

List<?> hotelBaseListNode = doc.selectNodes("/TransmitData/hotelList/hotel-response/hotelbase");

if (hotelBaseListNode != null && hotelBaseListNode.size() > 0)\{

...........

构建接口请求xml

public static String buildRequest(HotelListRequest hotelRequest) \{

String strXml = "";  
try \{  
Document xmldoc = DocumentHelper.createDocument();  
// 创建根节点  
Element hotelRoot = xmldoc.addElement("TransmitData");  
hotelRoot.addAttribute("version", "V.01");  
Element hotelListElement = hotelRoot.addElement("hotelList");  
Element hotelRequestElement = hotelListElement.addElement("hotel-request");  
  
hotelRequestElement.addElement("cityName").setText(hotelRequest.getCityId());

.............

strXml = xmldoc.asXML();  
return strXml;
