Java 如何从 html 中提取所有文本的链接和其他属性

To extract text or link or any other attribute value from several web elements you need to collect all these elements in a list and then to iterate over the list extracting the desired value from each web element object.
As following:

List<WebElement> elements = driver.findElements(By.tagName("h5"));
for(WebElement element : elements){
    String value = element.getText();
    System.out.println(value);
}

这将为您提供所有的链接

List<WebElement> links = driver.findElements(By.cssSelector(".top_cat a"));
for(WebElement link : links){
    String value = link.getAttribute("href");
    System.out.println(value);
}

On this specific page the structure is:
There are several blocks defined by class="col-12 col-sm-6 col-md-4 border all_cat" elements. Inside each such block several links and titles. Each a is below the class="col-12 col-sm-6 col-md-4 border all_cat" element and the title is below it a element. So, extracting the links and titles here can be done as following:

List<WebElement> blocks = driver.findElements(By.cssSelector(".all_cat"));
for(WebElement block : blocks){
    List<WebElement> links = block.findElements(By.xpath(".//a"));
    for(WebElement link : links){
        String linkValue = link.getAttribute("href");
        System.out.println("The link is " + linkValue);
        WebElement title = block.findElements(By.xpath(".//h5"));
        String titleValue = title.getText();
        System.out.println("The title is " + titleValue);
    }
}
