DocumentHelper 解析xml字符串

String xml=com.jetsen.platform.util.FileUtil.getFileContent(request.getSession().getServletContext().getRealPath("/WEB-INF/platform-app-interface.xml"));

org.dom4j.Document doc = org.dom4j.DocumentHelper.parseText(xml);

org.dom4j.Element stu = doc.getRootElement();

java.util.List> l=new java.util.ArrayList>();

java.util.List elist=stu.elements();

for(int i = 0 ; i < elist.size() ; i++)

{

org.dom4j.Element e=elist.get(i);

java.util.HashMap map=new java.util.HashMap();

map.put("id",e.attributeValue("id"));

map.put("beanId",e.attributeValue("beanId"));

map.put("methodName",e.attributeValue("methodName"));

map.put("paramClass",e.attributeValue("paramClass"));

map.put("example",e.getText());

l.add(map);

}

request.setAttribute("l",l);

SAXReader用法示例

/要上传的配置文件的路径

static String uploadCfgFile = "WEB-INF/conf/uploadfile.xml";

Document uploadDocument;//文档对象实体

Map uploadMap = new HashMap();

/** * 获取配置文件的绝对路径 *@param request *@return */

private String getUploadCfgFilePath(ServletRequest request){

return ((HttpServletRequest) request).getSession().getServletContext().getRealPath("uploadCfgFile");

}

** * 初始化配置文件 *@param request *@return */

private Document initUploadCfgDocument(ServletRequest request){

SAXReader saxReader = new SAXReader();

try {

//得到指定文件，以流的形式对文件进行序列化

FileInputStream fis = new FileInputStream(getUploadCfgFilePath(request));

uploadDocument = (Document) saxReader.read(fis);

} catch (FileNotFoundException e) {

logger.debug(e);

} catch (DocumentException e) {

logger.debug(e);

}

return uploadDocument;

/** * 获取配置文件 *@param request *@return */

private Document getUploadCfgDocument(ServletRequest request){

if (this.uploadDocument == null) {

this.uploadDocument = initUploadCfgDocument(request);

}

return this.uploadDocument;

}

/** * 获取某个指定ticket节点的配置属性 *@param request *@return */

private Map getUploadMap(ServletRequest request){

Document uploadDocument = getUploadCfgDocument(request); //得到XML的根节点(message)

Element root = uploadDocument.getRootElement();

Iterator tickets = root.element("body").element("ticketNotify").elementIterator(); //获取ticketNotify节点下所有的ticket节点的配置属性，并将其放到Map中

while (tickets.hasNext()) { Element ticket = (Element) tickets.next(); uploadMap.put("id", ticket.attributeValue("id"));

uploadMap.put("dealTime", ticket.attributeValue("dealTime"));

uploadMap.put("status", ticket.attributeValue("status")); } //Element.asXML方法，获得包括该标签的所有XML数据

// System.out.println(root.element("body").asXML());

return uploadMap;

}
