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>

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," "));
  

  
  

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());
