如何使用 Selenium 和 Python 单击 svg 标签内的下拉按钮 [英] How to click a dropdown button within a svg tag using Selenium and Python

问题描述

我有一个网站，我想在其中下载 Excel 文件.:

• 如何访问 '通过 Selenium-Python 的 rect' 类型元素
• 使用 selenium python 点击​​ svg

I have a website where i want to download an excel file. https://www.rivm.nl/media/smap/eenzaamheid.html

I want to be able to click the download button and then click download xls. To click the first button i tried the following:

WebDriverWait(driver, 10).until(EC.visibility_by_element_located(By.XPATH('//path[@d="M 11.6 5 L 11.6 17 M 7.4 12.6 L 11.6 17 L 15.799999999999999 12.6 M 3 19 L 3 21 L 21 21 L 21 19"]'))).click()

and

WebDriverWait(driver, 10).until(EC.visibility_by_element_located(By.XPATH('//path[@stroke-width="1.8"]'))).click()

WebDriverWait(driver, 10).until(EC.visibility_of_element_located(By.XPATH('//g[@aria-label="View export menu"]'))).click()

WebDriverWait(driver, 10).until(EC.visibility_of_element_located(By.XPATH('//g[@aria-label="Chart export menu"]'))).click()

For the last two i get the " 'str' object is not callable" error, the first two options just don't work at all.

I can't seem to be able to click the button. I can't really find an 'id' or an unique class/name (the print button has the same class value) for the button, which would make this a lot easier.

I think i would also not be able to then click the "XLS downloaden" as I can't find an ID here either.

So, how would i go about clicking the first button, and then clicking the "XLS downloaden" ?

解决方案

The desired element is a svg element so to click on the element instead of visibility_of_element_located() you have to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies:

• Using CSS_SELECTOR:

  driver.get("https://www.rivm.nl/media/smap/eenzaamheid.html")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.highcharts-container svg g[aria-label='View export menu'] rect"))).click()
  

• Using XPATH:

  driver.get("https://www.rivm.nl/media/smap/eenzaamheid.html")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='highcharts-container ']//*[name()='svg']//*[name()='g' and @aria-label='View export menu']//*[name()='rect']"))).click()
  

• Note : You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
