Answer 1

您需要findElements()而不是findElement() ：

List <WebElement> we = ffDriver.findElements(By.xpath("//*[@id='sf-menu']/li/a/b"));

Answer 2

You cannot get List by findElement (which returns WebElement). There are only 2 approaches for you

1 - Like elecxe's suggestion (recommended)

2 -

List<WebElement> we;
we.add(ffDriver.findElements(By.xpath("//*[@id='sf-menu']/li")));
we.add(ffDriver.findElements(By.xpath("//*[@id='sf-menu']/li[2]")));
... 
we.add(ffDriver.findElements(By.xpath("//*[@id='sf-menu']/li[n]")));

Answer 3

WebElement ul_Element = driver.findElement(By.id("sf-menu"));
List<WebElement> li_All = ul_Element.findElements(By.tagName("li"));
System.out.println(li_All.size());
for(int i = 0; i < li_All.size(); i++){
System.out.println(li_All.get(i).getText());
}

//OR

for(WebElement element : li_All){
System.out.println(element.getText());
}
