我们也可以用xml来定义一个信息更为丰富的UIMap.xml文件，比如，额外还添加控件所属的页，控件的类型，然后解析构建一个XMLParser类来读取相应的值。

相应的解析xml的代码：

1     public static String getLocator(String locatorID){ 2         InputStream ins=Thread.currentThread().getContextClassLoader() 3             .getResourceAsStream(FileConstants.XMLFILE_NAME); 4         if(ins==null){ 5             System.out.println("Missing UIMap.xml file."); 6             return null; 7         } 8          9         DocumentBuilderFactory fac=DocumentBuilderFactory.newInstance();10         DocumentBuilder builder=null;11         try {12             builder = fac.newDocumentBuilder();13         } catch (ParserConfigurationException pce) {14             System.out.println("Failing to new DocumentBuilder for runtime exception.");15             throw new RuntimeException(pce);16         }17         18         Document xmlDoc=null;19         try {20             xmlDoc = builder.parse(ins);21         } catch (SAXException se) {22             System.out.println("Failing to parse xml file for runtime exception.");23             throw new RuntimeException(se);24         } catch (IOException ie) {25             System.out.println("Failing to parse xml file for runtime exception.");26             throw new RuntimeException(ie);27         }28         29         XPathFactory pathFac=XPathFactory.newInstance();30         XPath xpath = pathFac.newXPath();31         32         XPathExpression exp=null;33         try {34             exp = xpath.compile("UIMap/Object[@ID='"+locatorID+"']/Attributes");35         } catch (XPathExpressionException e) {36             System.out.println("Failing to get locator for :"+locatorID);    37         }38         Node node=null;39         try {40             node = (Node)exp.evaluate(xmlDoc, XPathConstants.NODE);41         } catch (XPathExpressionException e) {42             43             e.printStackTrace();44         }finally{45             try{46                 if(ins!=null){47                     ins.close();48                 }49             }catch(Exception ex){50                 System.out.println("Failing to load UIMap.xml for runtime exception.");51                 throw new RuntimeException(ex);52             }53         }54         55         return node.getAttributes().getNamedItem("Locator").getNodeValue();56     }

测试代码：

1 selenium.type(UIMapParser.getLocator("UserName"), "seleniumtest");2 selenium.type(UIMapParser.getLocator("Password"), "seleniumtest");
