Get all child elements
提问by walshie4
In Selenium with Python is it possible to get all the children of a WebElement as a list?
在使用 Python 的 Selenium 中，是否可以将 WebElement 的所有子项作为列表？

Yes, you can achieve it by find_elements_by_css_selector("*")or find_elements_by_xpath(".//*").
是的，您可以通过find_elements_by_css_selector("*")或实现它find_elements_by_xpath(".//*")。
However, this doesn't sound like a valid use case to find all childrenof an element. It is an expensive operation to get all direct/indirect children. Please further explain what you are trying to do. There should be a better way.
但是，这听起来不像是查找元素的所有子元素的有效用例。获取所有直接/间接子级是一项昂贵的操作。请进一步说明您正在尝试做什么。应该有更好的方法。
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.stackoverflow.com")
header = driver.find_element_by_id("header")
# start from your target element, here for example, "header"
all_children_by_css = header.find_elements_by_css_selector("*")
all_children_by_xpath = header.find_elements_by_xpath(".//*")
print 'len(all_children_by_css): ' + str(len(all_children_by_css))
print 'len(all_children_by_xpath): ' + str(len(all_children_by_xpath))

Yes, you can use find_elements_by_to retrieve children elements into a list. See the python bindings here: http://selenium-python.readthedocs.io/locating-elements.html
是的，您可以使用find_elements_by_将子元素检索到列表中。在此处查看 python 绑定：http: //selenium-python.readthedocs.io/locating-elements.html
Example HTML:
示例 HTML：
<ul class="bar">
<li>one</li>
<li>two</li>
<li>three</li>
</ul>
You can use the find_elements_by_like so:
你可以这样使用find_elements_by_：
parentElement = driver.find_element_by_class_name("bar")
elementList = parentElement.find_elements_by_tag_name("li")
If you want help with a specific case, you can edit your post with the HTML you're looking to get parent and children elements from.
如果您需要特定案例的帮助，可以使用要从中获取父元素和子元素的 HTML 来编辑帖子。

Here is a code to get the child elements (In java):
这是获取子元素的代码（在java中）：
String childTag = childElement.getTagName();
if(childTag.equals("html"))
{
return "/html[1]"+current;
}
WebElement parentElement = childElement.findElement(By.xpath(".."));
List<WebElement> childrenElements = parentElement.findElements(By.xpath("*"));
int count = 0;
for(int i=0;i<childrenElements.size(); i++)
{
WebElement childrenElement = childrenElements.get(i);
String childrenElementTag = childrenElement.getTagName();
if(childTag.equals(childrenElementTag))
{
count++;
}
}
