如何使用Java搜索和突出显示某些单词？

Question

是否可以使用ctrl+f类的方法在网页上搜索单词？ 如何使用Java和Selenium搜索并突出显示网页上的某些单词？ 例如，我需要在以下网页上搜索单词“ test”： https : //www.wedoqa.com/blog/我试图将答案混在一起，所以我编写了这样的代码：

WebElement matchedElement = driver.findElement(By.xpath("//*[text()='test']"));
            ((JavascriptExecutor) driver).executeScript("arguments[0].setAttribute('style', 'background: yellow; border: 2px solid red;');", matchedElement);
            if(driver.getPageSource().contains(matchedElement.toString())) {
                System.out.println("The page contains word: " + matchedElement.toString());
            } else {
                System.out.println("The page does not contains word asdfghjkl");
            }

但是，然后我得到了这样的错误：

*** Element info: {Using=xpath, value=//*[text()='test']}

Answer 1

您可以使用JavaScript执行器突出显示匹配的元素。

样品：

//Partial Match of the word
WebElement matchedElement=driver.findElement(By.xpath("//*[contains(text(),'test')]"));
         (or)
//Exact Match of the word
WebElement matchedElement=driver.findElement(By.xpath("//*[text()='test']"));

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].setAttribute('style', 'background: yellow; border: 2px solid red;');", matchedElement);

Answer 2

您可以通过页面源进行验证：

if(driver.getPageSource().contains("test")){
    System.out.println("The page contains word test");
    }
