I want to extract all <li> element text that are under <ul>

I need to click on all elements BASIC, TRACKS, ...
My idea is to extract all elements in list then using list count and loop, I'll click on each and every element.
Need to check that each and every element is working even if new element is added I don't want to check code.

I tried travelling to child path but no success

Here is the java code that I tried.

    List<WebElement> tags = 
driver.findElements(By.xpath("//div[@class='headerarea']/ul/li")); 
for(int i=0;i<tags.size();i++) { 
while(???) { 
//driver.findElement(By.xpath("//div[@class='headerarea']/ul/li")).click(); 
}
}

List<WebElement> tags = driver.findElements(By.cssSelector(".headerarea ul>li")); 
for(WebElement e : tags) {
e.click();
}

Try below code :

List<WebElement> links = driver.findElements(By.tagName("li"));
for (int i = 1; i < links.size(); i++)
{
System.out.println(links.get(i).getText());
}

You can also use WebDriverWait if you are facing synchronization issue.

 WebDriverWait wait = new WebDriverWait(driver, 10);
List<WebElement> links = wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.tagName(li)));
for (int i = 1; i < links.size(); i++)
{
System.out.println(links.get(i).getText());
}
