java分享第十七天-01（封装操作xml类）

做自动化测试的人，都应该对XPATH很熟悉了，但是在用JAVA解析XML时，我们通常是一层层的遍历进去，这样的代码的局限性很大，也不方便，于是我们结合一下XPATH，来解决这个问题。
所需要的JAR包：
dom4j.jar
jaxen.jar
xmlbeans.jar

具体的代码如下：

public class ParseXml {private String filePath;private Document document; public ParseXml(String filePath) {     this.filePath = filePath;this.load(this.filePath);}  private void load(String filePath){File file = new File(filePath);if (file.exists()) {SAXReader saxReader = new SAXReader();try {document = saxReader.read(file);} catch (DocumentException e) {    System.out.println("文件加载异常：" + filePath);              }} else{System.out.println("文件不存在 : " + filePath);}          }  public Element getElementObject(String elementPath) {return (Element) document.selectSingleNode(elementPath);}  @SuppressWarnings("unchecked")public List<Element> getElementObjects(String elementPath) {return document.selectNodes(elementPath);}@SuppressWarnings("unchecked")public Map<String, String> getChildrenInfoByElement(Element element){Map<String, String> map = new HashMap<String, String>();List<Element> children = element.elements();for (Element e : children) {map.put(e.getName(), e.getText());}return map;}public boolean isExist(String elementPath){boolean flag = false;Element element = this.getElementObject(elementPath);if(element != null) flag = true;return flag;}public String getElementText(String elementPath) {Element element = this.getElementObject(elementPath);if(element != null){return element.getText().trim();}else{return null;}      }public static void main(String[] args) {ParseXml px = new ParseXml("config/TestBaidu.xml");List<Element> elements = px.getElementObjects("/*/testUI");}
}
