当页面上有这么多元素时，我如何 select 页面上的特定元素？ Selenium webdriver python；

Question

Essentially what I am trying to do is select just the "Reply" box which circled in red, but there are many of these in the page overall. My aim is to be able to select the first "Reply" box on every page. How can I select just the first reply box for every post (with this link just being an example)?

Currently this doesn't seem to work:

reply = driver.find_element_by_xpath("//*[@id='content']/div/div[2]/div/div/div/div[1]/article/div/aside/ul/li[1]/div/div[2]/div/ul/li[7]/button/span/img")
reply.click()

Many thanks.

Answer 1

First way:
The XPath to locate any of that replay buttons is

//button[@title="Reply"]

So the XPath to locate the first replay button is

(//button[@title="Reply"])[1]

So you can simply

driver.find_element_by_xpath('(//button[@title="Reply"])[1]').click()

Second way:
With the XPath above you can retrieve a list of all the replay buttons and then get the first element in the list and click on it as following:

replay_buttons = driver.find_elements_by_xpath('//button[@title="Reply"]')
replay_buttons[0].click()

You can use css_selector instead of XPath here as well:

replay_buttons = driver.find_elements_by_css_selector('button[title="Reply"]')
replay_buttons[0].click()

Answer 2

Inspecting the page i saw that the class name of this button is: <button class="Button Button--link">

So you can use driver.find_elements_by_class_name('Button Button--link') , which returns a list of all the buttons.
