java - Webdriver/Xpath/Java : Crawl DOM to click on 'Element with No Unique Identifier'

Question

我正在尝试从旅游网站的座位布局中查找并单击“可用”座位。挑战是，可用座位没有唯一标识符，而“已锁定”(已预订)座位则有“标题”形式的唯一标识符(请参阅 HTML)。我们如何让 WebDriver 跳过任何被阻塞的座位并在随机出现的座位布局上单击任何“可用”座位(图片)？

HTML 显示 2 个被封锁的座位(L2、L4)和中间的一个可用座位(L3)的结构

    <div style="max-width:695px;">
<div class="GXXXXXXX" style="display: none;" aria-hidden="true">
<div class="GXXXXXXX">
<div class="GXXXXXXX"> </div>
<div class="GXXXXXXX">
<table>
<colgroup>
<tbody>
<tr>
<tr>

Answer 1

这就是逻辑。查看DIV是否有title属性。如果没有座位也可以。根据您的需要更改逻辑。

List<WebElement> seats = driver.findElements(By.cssSelector("div.GXXXXXX.GXXXXXXX"));

for (WebElement seat : seats) {
   if(seat.getAttribute("title") != null){
        System.out.println("Seat is not available");
   }else{
        System.out.println("Seat is available");
        seat.click(); // break the loop if you wish
   }                    
}
