如何在python中制定Xpath表达式定位饼图(洋葱圈)中的所有元素? [英] How to formulate an Xpath expression in python locate all the elements in a pie chart (onion ring)?
问题描述
请在附件中找到饼图和 HTML.
我试图将鼠标悬停在附加饼图中的所有段上以打印应用程序显示的工具提示消息.
我编写了以下代码，但出于某种原因，它仅将鼠标悬停在 1 个线段上.
for element in driver.find_elements_by_xpath("//div[@class='join-strength-chart']"):元素 = driver.find_element_by_tag_name('path')webdriver.ActionChains(driver).move_to_element(elements).perform()时间.sleep(2)tooltipmessage = driver.find_element_by_xpath("//div[@class='d3-tipjoined-tables-chart n']")打印 tooltipmessage.text我确实尝试过使用 driver.find_elements_by_tag_name('path') 并且这也不起作用.
有人可以帮忙吗?谢谢
<块引用>XPath 表达式
//div[@class='join-strength-chart'] 将返回具有 class 属性且值为 join-strength-chart 的
这个表达:
//div[@class='join-strength-chart']//路径 将返回那些
，那么使用这个表达式是有意义的，因为它已经为您提供了所有的 join-strength-charts 可能没有，因为这将返回所有路径.<div class="join-strength-chart">

</div>
Please find attached is the pie chart and the HTML.
I am trying to hover over all the segments in the attached pie chart to print the tooltip message that the app shows.
I wrote the following code and it only hovers the mouse on 1 segment for some reason.
for elements in driver.find_elements_by_xpath("//div[@class='join-strength-chart']"):
elements = driver.find_element_by_tag_name('path')
webdriver.ActionChains(driver).move_to_element(elements).perform()
time.sleep(2)
tooltipmessage = driver.find_element_by_xpath("//div[@class='d3-tip joined-tables-chart n']")
print tooltipmessage.text
I did try using driver.find_elements_by_tag_name('path') and that doesn't work either.
Can someone please help?
Thank you
解决方案 The XPath expression
//div[@class='join-strength-chart']
will return a node-set of <div> elements that have a class attribute with the value join-strength-chart. You can loop the node-set if you have many of those (is that the case?)
This expression:
//div[@class='join-strength-chart']//path
will return a node-set of all the <path> elements that are inside those <div>s. If you only have one <div> of that class in the file, it would make sense to use this expression, since it already gives you all the <path> elements. If you have many join-strength-charts maybe not, since this will return all paths from all of them.
