Question

嘿，我看了，测试了2到3个小时，找不到任何对我有帮助的东西。我希望那些python类型谷歌搜索栏的东西并复制结果。

<div id="resultStats">Ungefähr 4.440.000 Ergebnisse<nobr> 
#that resultstats the text i want to copy the text which is inside ><

代码：

test = webdriver.Chrome('.\chromedriver.exe')
test.get('https://www.google.de')
test.find_element_by_id('lst-ib').send_keys('test123123')
webdriver.ActionChains(test).send_keys(Keys.ENTER).perform()
test.find_element_by_xpath('//*[@id="resultStats"]/text()').send_keys(Keys.CONTROL + 'v')

print(test)

错误：

Answer 1

尝试使用id来定位元素：

driver.find_element_by_id('resultStats')

这是一个完整的工作示例：

from selenium import webdriver

# create your webdriver
driver = webdriver.Chrome()

# open google
driver.get('http://www.google.com')

# locate the search field
search_box = driver.find_element_by_name('q')

# type "foo" into search field
search_box.send_keys('foo')

# execute a search
search_box.submit()

# locate the resultStats element
result_stats = driver.find_element_by_id('resultStats')

# print the text of resultStats
print(result_stats.text)

这将打印：

About 27,000,000 results (0.39 seconds)

Answer 2

您可以找到您的字符串并按如下方式打印：

yourText = test.find_element_by_xpath('//*[@id="resultStats"]').text

print(yourText)
