I'm starting with Selenium I have the following html code

<!DOCTYPE html>
<html lang="es" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>
    <div class="error">
      <h4>Error 1</h4>
      <p>Mi error 1</p>
    </div>
    <div class="error">
      <h4>Error 2</h4>
      <p>Este es el Error 2</p>
    </div>
    <div class="error">
      <h4>Error 3</h4>
      <p>Acceder</p>
    </div>
    <div class="ok">
      <h4>Esto OK</h4>
      <p>Esto esta OK</p>
    </div>
    <div class="error">
      <h4>Error 4</h4>
      <p>Otro error</p>
    </div>
  </body>
</html>

Well, what I want to retrieve is the value of the " p " tag with the text value "Sign in"

for this in the Selenium Webdriver in Python I have the following code

elementos=driver.find_elements_by_class_name("error") 
for elem in elementos   
    ### aqui quiero selecionar la etiqueta "<p>" de elem

but I'm not sure how I can select it to pick up the text.

I would try to use searches by xPath or by CSS. Here is an example of xpath:

driver.find_element_by_xpath(".//p[text()='Acceder']")

With this you do not need any loop.

Using any of the methods selenium gives you to locate an element (by name, by class, by id, by selector css, by xpath, ...) the result you get is a webelement . This object has the same methods as the driver , so you can search inside again by name, class, id, etc ...

For example, the following loop would take you the texts of the <p> tags that are inside another element with class "error" , which is more or less what you were trying to do in the code that you have put in the question :

elementos=driver.find_elements_by_class_name("error") 
for elem in elemento:
    p = elem.find_element_by_tag_name("p")
    print(p[0].text)

But you can save yourself from repeating searches if the items you select are directly the <p> , instead of the <div> . For this you need to express that you want "p elements that are children of a div element of the class" error. "This can be expressed by Xpath, or by CSS expressions, depending on what you are more used to, for example:

# Usando selector css
elementos = driver.find_element_by_css_selector("div.error p")

# Usando xpath
elementos = driver.find_element_by_xpath("//div[@class='error']/p")

In either of the two ways you get the list with the <p> that you were interested in and you can iterate through it:

for p in elementos:
    print(p.text)

Now, if you do not need all the p , but only those containing the text 'Access' a more elaborate Xpath expression that would return only those would be:

elementos = driver.find_element_by_xpath("//div[@class='error']/p[text()='Acceder']")
