How to print the extracted texts obtained from the web page with a space delimiter using Selenium and Java

Question

With the code String result = driver.findElement (By.id ("ulDezenas")).GetText (); I can get the result 001122334455, which is present in uldezenas. I want to get the numbers, however separated, in this way 00 11 22 33 44 55.

I already tried the split command, but I could not, unfortunately.

HTML

<ul class="numbers diaDeSorte" id="ulDezenas">
    <li>00</li>
    <li>11</li>
    <li>22</li>
    <li>33</li>
    <li>44</li>
    <li>55</li>
    <li>66</li>
</ul>

Answer 1

Get the parent(ul) webelement first; then find elements by tag name 'li' which returns a list. Iterate over it and get the text.

WebElement ul = driver.findElement(By.id("ulDezenas"));

    for (WebElement li : ul.findElements(By.tagName("li"))) {
        System.out.println(li.getText());
    }

Answer 2

To extract the numbers separately in the following fashion, 00 11 22 33 44 55 etc you need to create a List you can use either of of the elements and then use StringJoiner Class to add the space character and you can use either of the following Locator Strategies:

• Using StringJoiner of Java 8 and later

  • Using cssSelector:

    List<WebElement> elementList = driver.findElements(By.cssSelector("ul.numbers.diaDeSorte#ulDezenas li"));
    ArrayList<String> values = new  ArrayList<>();
    for(WebElement element:elementList)
        values.add(element.getText());
    StringJoiner joiner = new StringJoiner(" ");
    for (String item : values)
        joiner.add(item.toString());
    System.out.println(joiner.toString());
    

  • Using xpath:

    List<WebElement> elementList = driver.findElements(By.xpath("//ul[@class='numbers diaDeSorte' and @id='ulDezenas']//li"));
    ArrayList<String> values = new  ArrayList<>();
    for(WebElement element:elementList)
        values.add(element.getText());
    StringJoiner joiner = new StringJoiner(" ");
    for (String item : values)
        joiner.add(item.toString());
    System.out.println(joiner.toString());
    

• Using Stream and Collectors of Java 9 and later

  List<WebElement> elementList = driver.findElements(By.cssSelector("ul.numbers.diaDeSorte#ulDezenas li"));
  ArrayList<String> values = new  ArrayList<>();
  for(WebElement element:elementList)
      values.add(element.getText());
  System.out.println(values.stream().
                  map(Object::toString).
                  collect(Collectors.joining(" ")).toString());
  

• Using org.apache.commons.lang3.StringUtils:

  List<WebElement> elementList = driver.findElements(By.xpath("//ul[@class='numbers diaDeSorte' and @id='ulDezenas']//li"));
  ArrayList<String> values = new  ArrayList<>();
  for(WebElement element:elementList)
      values.add(element.getText());
  System.out.println(org.apache.commons.lang3.StringUtils.join(values," "));
