该例子主要使用SAXReader对XML进行操作,browse.xml是Ango框架里面的XML文件
采用两种方法,第一种的全部是iterator,另外一种采用了部分的for each
代码如下
private void doBrowse(ServletContextEvent sce) { HashMap<String,BrowseBean1> map1 = new HashMap<String,BrowseBean1>(); SAXReader saxReader = new SAXReader(); Document document = null; // xml文件位置 String path = this.getClass().getResource("/").getPath(); //String pString = this.getClass().getResource(pString).getPath(); String filePath = path.substring(0, path.length()- "classes/".length())+"browse.xml"; //logger.warn(path); //logger.warn(filePath); try { document = saxReader.read(new File(URLDecoder.decode(filePath, "utf-8"))); } catch (UnsupportedEncodingException e) { // 路径中文解码错误 e.printStackTrace(); } catch (DocumentException e) { e.printStackTrace(); logger.warn("查询操作的xml文档异常"); } List list = document.selectNodes("/BrowseElements/element/@flag"); //logger.warn(list); Iterator iter = list.iterator(); /** * 自己写的方法,里面没有全部使用迭代器,用的for each 循环 start */ while(iter.hasNext()){ Attribute attribute = (Attribute) iter.next(); String flag = attribute.getValue(); List listTemp1 = document.selectNodes("/BrowseElements/element[@flag=‘" + flag + "‘]/@pageSize"); Iterator iterTemp1 = listTemp1.iterator(); int pageSize = 0; while (iterTemp1.hasNext()) { Attribute attribute1 = (Attribute) iterTemp1.next(); pageSize = Integer.parseInt(attribute1.getValue()); } BrowseBean1 browseBean1 = new BrowseBean1(); browseBean1.setPageSize(pageSize); List listTemp2 = document.selectNodes("/BrowseElements/element[@flag=‘" + flag + "‘]/sql/@value"); LinkedHashMap<String,BrowseBean2> map2 = new LinkedHashMap<String,BrowseBean2>(); for(Object ob : listTemp2){ //System.out.println(ob); String value = ((Attribute) ob).getValue(); //System.out.println(value);
