我想通过使用Selenium从表中获取内容到数组。

Question 1

嘿，伙计们，我想通过使用Selenium从网站的表格中获取内容。

here my first try:

from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://www.javatpoint.com/html-table')
texts = driver.find_elements_by_xpath("//td/table")
print(texts)
the retult
然后我想通过使用以下方法将其改为textcontent
get_property('textContent')
并出错说AttributeError：'NoneType'对象没有属性'get_property'。
所以我想知道如何获得表格内容并将其转为数组
ps. python version 3.7.4

Question 2


          
           
            如果你正在寻找表格中的所有文本，只需使用
            
             .text
            
            。像这样。
           
           from pprint import pprint
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://www.javatpoint.com/html-table')
texts = [i.text for i in driver.find_elements_by_xpath("//td/table")]
pprint(texts)
Output:
['Tag Description\n'
 '<table> It defines a table.\n'
 '<tr> It defines a row in a table.\n'
 '<th> It defines a header cell in a table.\n'
 '<td> It defines a cell in a table.\n'
 '<caption> It defines the table caption.\n'
 '<colgroup> It specifies a group of one or more columns in a table for '
 'formatting.\n'
 '<col> It is used with <colgroup> element to specify column properties for '
 'each column.\n'
 '<tbody> It is used to group the body content in a table.\n'
 '<thead> It is used to group the header content in a table.\n'
 '<tfooter> It is used to group the footer content in a table.',
 'First_Name Last_Name Marks\n'
 'Sonoo Jaiswal 60\n'
 'James William 80\n'
 'Swati Sironi 82\n'
 'Chetna Singh 72',
 'First_Name Last_Name Marks\n'
 'Sonoo Jaiswal 60\n'
 'James William 80\n'
 'Swati Sironi 82\n'
 'Chetna Singh 72',
 'Name Last Name Marks\n'
 'Sonoo Jaiswal 60\n'
 'James William 80\n'
 'Swati Sironi 82\n'
 'Chetna Singh 72',
 'Name Last Name Marks\n'
 'Sonoo Jaiswal 60\n'
 'James William 80\n'
 'Swati Sironi 82\n'
 'Chetna Singh 72',
 'Name Mobile No.\nAjeet Maurya 7503520801 9555879135',
 'Name Ajeet Maurya\nMobile No. 7503520801\n9555879135',
 'Element Chrome IE Firefox Opera Safari\n<table> Yes Yes Yes Yes Yes']
如果你想使用get_property('textContent')，你可以做到。
from pprint import pprint
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://www.javatpoint.com/html-table')
texts = [i.get_property('textContent') for i in driver.find_elements_by_xpath("//td/table")]
pprint(texts)
Output:
['\n'
 'TagDescription\n'
 '<table>It defines a table.\n'
 '<tr>It defines a row in a table.\n'
 '<th>It defines a header cell in a table.\n'
 '<td>It defines a cell in a table.\n'
 '<caption>It defines the table caption.\n'
 '<colgroup>It specifies a group of one or more columns in a table for '
 'formatting.\n'
 '<col>It is used with <colgroup> element to specify column properties for '

 '<thead>It is used to group the header content in a table.\n'

 '  Mobile No.\n'

 '  \n'

 '  \n',

Question 3


          
           
            
             
              
               
                这将把表格单元格内容存储到一个数组中
               
               from selenium import webdriver
from selenium.webdriver.common.by import By
driver = webdriver.Chrome('/usr/local/bin/chromedriver')  # Optional argument, if not specified will search path.
driver.implicitly_wait(15)
driver.get("https://www.javatpoint.com/html-table");
table_rows= driver.find_elements(By.XPATH,"(//p[contains(text(),'HTML table')]/following-sibling::table[@class='alt'])[1]//tr/td")
for rows in table_rows:
    #print rows.text
    x.append( rows.text)
print x
driver.quit()
Output
