我无法迭代（定位）从 selenium python 提交的此输入，每次 id 更改，并且完整的 Xpath 也不起作用

Question

Hy all, I am unable to iterate this input filed from selenium python, every time id changed, and full Xpath is also not working. URL: https://support.google.com/blogger/answer/3091837

i tried already: -

driver.find_element_by_name("blog_URL").click()
driver.find_element_by_xpath('//*[@id="render_api158171433--blog_URL"]').click()
driver.find_element_by_xpath("/html/body/div[8]/div/section/div/div[1]/article/section/div/div[2]/div[1]/form/div[1]/input").click()
driver.find_element_by_id('render_api535892960--blog_URL')[2].click()

Answer 1

Your <input> has an slippery id but its name seems to be unique name="blog_URL" , so you could use find_element_by_name

Anyway when an id or class changes every time, findById or xpath with exact values does not help.

You can try other approaches such as: looking for neighbors, parents, children,sibling, etc., which can be located and then navigate until to find your slippery <input> . This will be a little expensive!!

Samples according to your html:

form has an unique id

• locate form by id = harassment

parentElement = driver.find_element_by_id("myFormId")

• get all child elements

childElementsOfForm = parentElement.find_elements_by_xpath(".//*")

• Iterate elements and get the second and perform a new find inside of this element. We can see that our <input> in another child of it.

search all inputs in form

parentElement = driver.find_element_by_id("myFormId")
elementList = parentElement.find_elements_by_tag_name("input")

Iterate them and search an input whose id starts with render_api
