If you are using Selenium, you should try this:

<pre class="lang-py prettyprint-override"><code>driver = webdriver.Chrome()
driver.get(url)

element = WebDriverWait(driver, 20).until(
EC.presence_of_element_located((By.CLASS_NAME,"myclass")))

html = driver.page_source
dynamic_text = driver.find_elements_by_xpath('//div') #this will be a list of all divs on the page, they all will be selenium object
</code></pre>

Also keep in mind, that some script generated content on the page may not be there, depending on your driver configuration

I don't know which <code>class</code> you used, but the class when inspecting with Browser, and the class from source page is not the same : the <a href="https://en.wikipedia.org/wiki/Document_Object_Model" rel="nofollow noreferrer">DOM</a> is modified by JavaScript, after loading the page source code.

Try this: 

<pre><code>driver = webdriver.Chrome()
driver.get(url)
try:
 elements = WebDriverWait(driver, 20).until(
 EC.presence_of_all_elements_located((By.XPATH,
 "//div[contains(@class, 'trainBasicInfo ng-scope')]"))) 
 # By.XPATH gives more flexibility
 for element in elements: 
 print(element)
except:
 # print("Couldnt locate element")
 raise # except with no Exception specified is prohibited

</code></pre>

From <code>inspect</code> with Chrom Dev Tools: 
<a href="https://i.stack.imgur.com/vONlG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vONlG.png" alt="enter image description here"></a>

From <code>view-source:https://www.rail.co.il/pages/trainsearchresultnew.aspx?FSID=4170&amp;TSID=5000&amp;Date=20190630&amp;Hour=1000&amp;IOT=true&amp;IBA=false&amp;TSP=1561835762832</code>: 
<a href="https://i.stack.imgur.com/9QGfg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9QGfg.png" alt="enter image description here"></a> 

The output is, as follows:

I'm trying to scrape an HTML page with this code :
<pre><code>driver = webdriver.Chrome()
driver.get(url)
try:
 element = WebDriverWait(driver, 20).until(
 EC.presence_of_element_located((By.CLASS_NAME,
 &quot;myclass&quot;))) 
 html = driver.page_source
 soup = bs(html, &quot;lxml&quot;)
 print(html)
 dynamic_text = soup.find_all(&quot;div&quot;, {&quot;class&quot;: &quot;myclass&quot;}) 
except:
 print(&quot;Couldnt locate element&quot;)
</code></pre>
The html page is opened but in my IDE console I see the except message. As it seems, the div with the class_name &quot;myclass&quot; isn't found. However, when I inspect the html page that I got I see there the div with that class name.
The div in the HTML :
<pre><code>&lt;div role=&quot;radio&quot; data-ng-attr-id=&quot;{{radioId}}&quot; data-ng-attr-tabindex=&quot;{{directToShow === strVm.data.selectedDirectToShow ? '0' : '-1'}}&quot; data-ng-attr-aria-checked=&quot;{{directToShow === strVm.data.selectedDirectToShow ? 'true' : 'false'}}&quot; class=&quot;trainBasicInfo ng-scope&quot; data-ng-if=&quot;directToShow.date == undefined&quot; data-ng-click=&quot;strVm.onSelectDirectToShow(directToShow, $event)&quot; data-ng-class=&quot;{'active': directToShow === strVm.data.selectedDirectToShow}&quot; id=&quot;railRadio_423&quot; tabindex=&quot;-1&quot; aria-checked=&quot;false&quot;&gt;
</code></pre>
I put in comment the <code>WebDriverWait</code> and I saw the output of the print(html) command. In the output of the print I don't see the div, but when I check the inspect of the chrome page that was opened I can see the div.

In my web-scraping, some divs don't appear
