查找表selenium时未找到元素

Question

我正试图读取表并获得地址和值列的值。返回找不到元素错误。页面:https://etherscan.io/token/0xB8c77482e45F1F44dE1745F52C74426C631bDD52#balances

代码我代码:

driver=webdriver.Firefox()
ga=pandas.read_csv("contracts/adresses.csv")
for i in range (ga.size-1):
fj=ga.iloc[i][0]
# driver.get("https://etherscan.io/address/"+str(fj))
driver.get("https://etherscan.io/token/0xB8c77482e45F1F44dE1745F52C74426C631bDD52#balances")
wait = WebDriverWait(driver,10)
frame = wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID,"tokeholdersiframe")))
print("udj")


simpleTable = driver.find_element(By.XPATH,"/html/body/div[2]/div[3]/table")


rows = simpleTable.find_elementsBy.TAG_NAME("tr")

for i in range(1,len(rows)):
cols = i.find_elements(By.TAG_NAME("td"))
for g in cols:
g.getText()

HTML代码:

Answer 1

代码中有很多语法错误:

rows = simpleTable.find_elementsBy.TAG_NAME("tr")

应该

rows = simpleTable.find_elements(By.TAG_NAME,"tr")

和

cols = i.find_elements(By.TAG_NAME("td"))

应该

cols = rows[i].find_elements(By.TAG_NAME,"td")

在python中使用.text或.get_attribute("innerText")从WebElement中获得Text应该是这样的:

print(g.text)

试试下面的代码:

simpleTable = driver.find_element(By.XPATH, "//div[@id='maintable']//table")
rows = simpleTable.find_elements(By.TAG_NAME,"tr")
for i in range(1,len(rows)):
cols = rows[i].find_elements(By.TAG_NAME,"td")
for g in cols:
print(g.text)

Answer 2

!pip install selenium (jupyter notebook)

或

pip install selenium ( command prompt)

安装后再试!
