xpath可以用这种方式吗？

Question

System.out.println("The U value: " + u); 
Statement stmt3 = null; 
ResultSet srs3 = null; 
List28 = new ArrayList<String>(); 
stmt3 = conn.createStatement(); 
String query = "SELECT [USERS_SYS_ID],[GROUPS_SYS_ID] as groupID FROM [USERS_GROUPS] WHERE [USERS_SYS_ID] = " + (u + 1); 
srs3 = stmt3.executeQuery(query); 
while (srs3.next()) { 
    List28.add(srs3.getString("groupID")); 
} 
System.out.println("Group ID: " + List28); 

String z = "0"; 
z = null; 
z = ("T_GROUP_" + List28.get(0)); 
driver.findElement(By.xpath(".//*[@id=z")).click(); 

System.out.println("Group ID: " + driver.findElement(By.xpath(".//*[@id=z]"))); 

假设的u值是2和List28给予回报2

是否可以运行点击这样

driver.findElement(By.xpath(".//*[@id=z")).click(); 

Answer 1

的XPath的是，可以使用String .format（）

String xpathExpression = String.format(".//*[@id='%s']", z); 
driver.findElement(By.xpath(xpathExpression)).click(); 

或简单地

driver.findElement(By.xpath(".//*[@id='"+z+"']")).click();
