如何使用Selenium和Python从由空格分隔的textnodes中获取文本 [英] How to get text from textnodes seperated by whitespace using Selenium and Python
问题描述
我在此页面上:
https://fantasy.premierleague.com/statistics
当您单击任何"i"时，播放器旁边的图标，将显示一个弹出窗口.然后，我想获得玩家的姓.这就是检查元素"的方式.看起来像(空白"实际上出现在一个框内):
When you click on any "i" icon next to a player, a popup window appears. Then, i want to get the surname of the player. This is how "inspect element" looks like ("whitespace" actually appears within a box):
<h2 class="ElementDialog__ElementHeading-gmefnd-2 ijAScJ">
Kevin
whitespace
De Bruyne
我想做的是获取空格后出现的文本.我可以使用以下方式获取全文(即姓名和姓氏):
What i want to do is to take the text that appears after the whitespace. I can get the full text (ie both name and surname) using this:
player_full_name = driver.find_element_by_xpath('//*[@class="ElementDialog__ElementHeading-gmefnd-2 ijAScJ"]').text
但是我怎样才能只获得姓氏(即空格后出现的内容)?请注意，对于其他玩家，可能是这样的:
but how can i get the surname only (ie what appears after the whitespace)? Note that for other players it could have been like this:
<h2 class="ElementDialog__ElementHeading-gmefnd-2 ijAScJ">
Gabriel Fernando
whitespace
de Jesus
或这样:
<h2 class="ElementDialog__ElementHeading-gmefnd-2 ijAScJ">
Dean
whitespace
Henderson
即拆分文本并采用最后一个或两个元素将不起作用.
ie splitting the text and taking the last one or two elements will not work.
推荐答案
播放器的姓氏是其父级中第二个或最后一个文本节点定位器策略:
The surname of the player is the second or last text node within it's parent WebElement. So extract the surname e.g. De Bruyne from Kevin De Bruyne you can use either of the following Locator Strategies:
-
使用
CSS_SELECTOR， childNodes 和strip():
driver.get("https://fantasy.premierleague.com/statistics")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//table//tbody/tr/td/button"))).click()
print( driver.execute_script('return arguments[0].lastChild.textContent;', WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "h2.ElementDialog__ElementHeading-gmefnd-2")))).strip())
控制台输出:
Console Output:
De Bruyne
使用 CSS_SELECTOR ， childNodes 和 splitlines():
driver.get("https://fantasy.premierleague.com/statistics")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//table//tbody/tr/td/button"))).click()
print( driver.execute_script('return arguments[0].lastChild.textContent;', WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "h2.ElementDialog__ElementHeading-gmefnd-2")))).splitlines())
控制台输出:
Console Output:
['De Bruyne']
注意:您必须添加以下导入:
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
