java - 使用 Selenium 按以字母开头的 id 过滤 DOM 元素

Question

我正在尝试找到一种解决方案，以使用 selenium 获取页面的所有元素以稍后填充测试值。我能够获取所有元素，但我想过滤掉以字母 's' 开头的元素。所以我可以获得 sFirst、sLast、sAddress 等元素。我可以使用下面的代码。但我不确定这里的 's' 之后应该是什么。

// I am not sure what should be after 's' here.
List<WebElement> allEle = driver.findElements(By.id("s *")); 

或者

// instead of all elements, need to find ids starting with 's'
List<WebElement> allEle = driver.findElements(By.cssSelector("*"));


//iterate and print
for (WebElement ele : allEle ) {
  ele.getAttribute("id");     // id of each element
  ele.getText();

  System.out.println ("Element :" + ele.getAttribute("id") + ": Test :" +ele.getText());

}

编辑注释:在代码块内添加 for 循环结束大括号

您可以按如下方式查找不以 s 开头的元素:

List<WebElement> allEle = driver.findElements(By.cssSelector("*:not([id^='s'])"));

如果您想查找以 s 开头的所有元素:

List<WebElement> allEle = driver.findElements(By.cssSelector("[id^='s']"));

编辑:

要过滤掉以 sA、sB 等开头的元素，我认为这可行:

List<WebElement> allEle = driver.findElements(By.cssSelector("[id^='s']"));
String letters[] = {"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"};
foreach (String letter in letters)
{
    allEle = allEle.findElements(By.cssSelector("*:not([id^='s" + letter + "']));
}

你也可以尝试这个，但我认为它可能会很慢:

List<WebElement> allEle = driver.findElements(By.cssSelector("[id^='s']" + 
    ":not([id^='sA']," + 
    "[id^='sB']," + 
    "[id^='sC']," + 
    "[id^='sD']," + 
    "[id^='sE']," + 
    "[id^='sF']," + 
    "[id^='sG']," + 
    "[id^='sH']," + 
    "[id^='sI']," + 
    "[id^='sJ']," + 
    "[id^='sK']," + 
    "[id^='sL']," + 
    "[id^='sM']," + 
    "[id^='sN']," + 
    "[id^='sO']," + 
    "[id^='sP']," + 
    "[id^='sQ']," + 
    "[id^='sR']," + 
    "[id^='sS']," + 
    "[id^='sT']," + 
    "[id^='sU']," + 
    "[id^='sV']," + 
    "[id^='sW']," + 
    "[id^='sX']," + 
    "[id^='sY']," + 
    "[id^='sZ']")));
