在xpath的第n个实例上捕获元素会减慢多次运行后的代码运行速度

  driver.switchTo().defaultContent();
                        wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(0));

                        int closePaths = driver.findElements(By.xpath("//*[text()[contains(.,'Message Map Data - View and Edit the Message Map Data')]]/following-sibling::div[@id='fb_buttons']/span[2]")).size();
                        for (int j = 1; j <= closePaths; j++) {
                            String closePath = "(//*[text()[contains(.,'Message Map Data - View and Edit the Message Map Data')]]/following-sibling::div[@id='fb_buttons']/span[2])";
                            String xpathNumber = "[" + j + "]";
                            closePath = closePath + xpathNumber;

                            try {
                                driver.findElement(By.xpath(closePath)).click();
                            } catch (Exception e) {}
                        }

                        driver.switchTo().defaultContent();
                        wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(0));
                        wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(2));
                        driver.findElement(By.id("navFind1")).click();
