Java 解析XML 之 DOM4J 解析 XML 分析测试

DOM4J解析 XML 测试代码，

测试环境： JDK 6

Add jar: dom4j-1.6.jar 、jaxen-1.1-beta-6.jar(xpath 支持)

import java.io.File; import java.net.MalformedURLException; import java.util.ArrayList; import java.util.Iterator; import java.util.List; import org.dom4j.Document; import org.dom4j.DocumentException; import org.dom4j.Element; import org.dom4j.io.SAXReader; public class DOM4JParseService { // 从文件读取XML，输入文件名，返回XML文档 public static Document read(String fileName) throws MalformedURLException, DocumentException { SAXReader reader = new SAXReader(); Document document = reader.read(new File(fileName)); return document; } public static void main(String[] args) { Document doc = null; try { doc = read("D:\\profile.xml"); } catch (Exception e) { e.printStackTrace(); } List<AFile> files = getAFileList(doc); System.out.println("files.size():-----" + files.size()); for (AFile file : files) { System.out.println(file.toString()); } DBConfig dBConfig = getDBConfig(doc); System.out.println(dBConfig.toString()); getWLMInfo(doc); } public static List getAFileList(Document doc) { List filelist = doc.selectNodes("root/IOInfo/files/file"); List<AFile> afiles = new ArrayList<AFile>(); for (Element file : (List<Element>) filelist) { AFile afile = new AFile(); afile.setCategory(file.attributeValue("cate")); afile.setIn(file.elementText("in")); afile.setOut(file.elementText("out")); afile.setAwk(file.elementText("awk")); afiles.add(afile); } return afiles; } public static DBConfig getDBConfig(Document doc) { Element xmldbconfig = (Element) doc.selectNodes("root/DBConnection").get(0); DBConfig dBConfig = new DBConfig(); dBConfig.setIp(xmldbconfig.elementText("location")); dBConfig.setDbname(xmldbconfig.elementText("database")); dBConfig.setDbuser(xmldbconfig.elementText("userName")); dBConfig.setDbpassword(xmldbconfig.elementText("password")); return dBConfig; } public static void getWLMInfo(Document doc) { List wLMInfoList = doc.selectNodes("root/WLMInfo/WLMs"); // List<AFile> afiles = new ArrayList<AFile>(); System.out.println("==================WLMInfo========================="); for (Element wLMInfo : (List<Element>) wLMInfoList) { System.out.println(wLMInfo.attributeValue("tp")); for (Iterator i = wLMInfo.elementIterator("name"); i.hasNext();) { Element name = (Element) i.next(); System.out.println("name: " + name.getTextTrim()); } System.out.println("-------------------"); } System.out.println("=================WLMInfo=========================="); } }
