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");
}
}
