網站上的文字未使用 selenium 抓取

Question

我正在嘗試從我們訂購輪胎的網站發送文本到 discord 嵌入。 我登錄該站點，搜索一個項目，然后看到它可用。 我希望 discord 嵌入顯示可訂購的數量，但它不顯示任何內容。 它顯示的其他元素不顯示Available 、 Alt Plant 、 Tire Tread和Est Delivery 。

（如果我的代碼很亂，我深表歉意，我是新手，過去一個小時我一直在玩它）

# Finding the Quantity + Tire Description
    try:
        available1 = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, "//*[@id='resultsTable']/tbody/tr[2]/td[9]"))
        )
        altPlant1 = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, "/html/body/div[2]/div[2]/div[2]/div/form/div[1]/table/tbody/tr[2]/td[10]"))
        )
        estDelivery1 = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, "/html/body/div[2]/div[2]/div[2]/div/form/div[1]/table/tbody/tr[2]/td[11]"))
        )
        tireSize1 = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, "/html/body/div[2]/div[2]/div[2]/div/form/div[1]/table/tbody/tr[2]/td[5]"))
        )
        tireTread1 = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, "//*[@id='resultsTable']/tbody/tr[2]/td[7]"))
        )
        itemCode1 = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.XPATH, "/html/body/div[2]/div[2]/div[2]/div/form/div[1]/table/tbody/tr[2]/td[2]"))
        )
    except:
        driver.quit()
    
    available = available1.text
    altPlant = altPlant1.text
    estDelivery = estDelivery1.text
    tireSize = tireSize1.text
    tireTread = tireTread1.text
    itemCode = itemCode1.text

    print(available)
    print(altPlant)
    print(estDelivery)
    print(tireSize)
    print(tireTread)
    print(itemCode)
    
# Discord Embed Setup   
    embed = Embed(
        description='**Stock available for item number '+pItemNumber+'**',
        color=0x0d0d22,
        timestamp='now'  # sets the timestamp to current time
        )

    embed.set_author(name='Pirelli Stock Check')
    embed.add_field(name='Item Number', value=itemCode, inline=True)
    embed.add_field(name='Tire Description', value=tireTread+' '+tireSize, inline=True)
    embed.add_field(name='Available', value=available+' In Stock', inline=False)
    embed.add_field(name='Alt Plant', value=altPlant+ ' In Stock', inline=True)
    embed.add_field(name='Est Delivery', value=estDelivery+'1', inline=True)
    embed.set_footer(text='Tires Tools', icon_url='https://cdn.discordapp.com/avatars/628005829840470037/8286685de0f2d7d94d94e020caf3265d.png?size=128')

    hook.send(embed=embed)

    print("Embed sent to discord!")

我需要的 4 個字符串也在源代碼中。 tireTread = CINTURATO P7 ， available = 12 ， altPlant = 7和estDelivery = 08/24/2020 。

這是通過我的 discord 嵌入得到的。

知道我做錯了什么嗎？ 如果您需要更多信息，請告訴我。

您可以通過 ID 或 CSS class 查找元素：

table = WebDriverWait(driver,10).until(EC.presence_of_element_located((By.ID, "tabla_evolucion")))


table = WebDriverWait(driver,10).until(EC.presence_of_element_located((By.class, "css-class sub-class")))

我建議您按 ID 查找表，然后循環讀取行。 也許您需要根據需要更改以下代碼。

table_id = self.driver.find_element(By.ID, 'table_id')
rows = table_id.find_elements(By.TAG_NAME, "tr") # get all of the rows in the table
for row in rows:
    # Get the columns (all the column 2)        
    col = row.find_elements(By.TAG_NAME, "td")[1] #note: index start from 0, 1 is col 2
    print col.text #prints text from the element
