用DOM读取XML文件的案例
//用DOM读取XMLpublic class A { Document document = null; public void t() { DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); try { DocumentBuilder builder = factory.newDocumentBuilder(); document = builder.parse(configPath); Node rootNode = document.getFirstChild(); System.out.println(rootNode.toString()); NodeList logFileList = rootNode.getChildNodes(); for (int i = 1; i < logFileList.getLength(); i += 2) { Node curNode = logFileList.item(i); System.out.println("Log file" + i + " : " + curNode.toString()); NamedNodeMap map = curNode.getAttributes(); for (int j = 0; j < map.getLength(); j++) { System.out.println("Log file" + i + " :key: " + map.item(j).getNodeName()); System.out.println("Log file" + i + " :value: " + map.item(j).getNodeValue()); } NodeList columns = curNode.getChildNodes(); for (int j = 1; j < columns.getLength(); j += 2) { System.out.println("column" + j + " : " + columns.item(j).toString()); } } } catch (ParserConfigurationException pce) {pce.printStackTrace(); } catch (SAXException f) { f.printStackTrace(); } catch (IOException c) { c.printStackTrace(); } } public static void main(String[] args){ A a =new A(); a.t(); }}//XML文件<?xml version="1.0" encoding="UTF-8"?> <LOG_MAPPING> <LOG_FILE fileNamePattern="ad.+\.log" class="com.nec.jp.bigm.log.ADLogCounter"> <column name="date"/> <column name="carrier"/> <column name=""/> </LOG_FILE> <LOG_FILE fileNamePattern="access.+\.log" class="com.nec.jp.bigm.log.ADLogCounter"> <column name=""/> <column name=""/> <column name=""/> </LOG_FILE> </LOG_MAPPING>
