You find the parent div first, then locate all target elements, then count them.
你先找到父div，然后定位所有目标元素，然后统计它们。
List<WebElement> forms = driver.findElements(By.cssSelector(".product_row form"));
int count = forms.size();

In general, I would use some way to find all of the elements that I want, either using xpath or css selectors, and then just count how many results are returned.
通常，我会使用某种方法来查找我想要的所有元素，无论是使用 xpath 还是 css 选择器，然后只计算返回了多少结果。

Here are two solutions:
这里有两个解决方案：
You could either select by xpath
您可以通过 xpath 选择
driver.findElements(By.xpath("//div[@class='product_row']/form"))
or you could select by CSS query as mentioned by user1177636
或者您可以通过user1177636提到的 CSS 查询进行选择
driver.findElements(By.cssSelector(".product_row>form"))
回答by Sravan
You can find the size of elements by using the following statement
您可以使用以下语句找到元素的大小
System.out.println(driver.findElements(By.xpath("//div[@class='product_row']/form")).size());
where findElements method returns count value that all elements in that a page consists with xpath //div[@class='product_row']/form
其中 findElements 方法返回该页面中所有元素由 xpath //div[@class='product_row']/form 组成的计数值
in your case it will return "3" as result
在你的情况下，它会返回“3”作为结果
