我想从动态网站上的表中检索所有信息,并且具有以下代码:
/home
但是,我一直收到错误消息,但到目前为止还行不通。如何检索表格信息? 非常感谢!
错误: RowsOfTable = table.get_attribute(“ tr”) AttributeError:“列表”对象没有属性“ get_attribute”

这是获取产品详细信息的代码
tableloadwait = (wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, ".panel-body"))))
driver.find_element_by_xpath("//span[contains(.,'Product Details')]").click()
rows = driver.find_elements_by_xpath("//span[contains(.,'Product Details')]/ancestor::div[@class='accordion-top-border']//tr[(@ng-repeat='attr in attributes' or @ng-repeat='field in fields') and @class='visible-xs']")
for rowNum in range(len(rows)):
print(rows[rowNum].get_attribute('innerText'))
driver.quit()
我们必须根据您的要求调整值或破坏值。
如果要基于行文本获取数据,请使用以下内容。
upcData = driver.find_element_by_xpath("//strong[.='UPC']/parent::td").get_attribute('innerText').replace('UPC','').replace('\n','').replace(' ','')

首先使用适当的+按钮扩展手风琴,然后选择表格。添加等待项出现。如果需要另一个表,请将//we bind our HP element to a variable
const hp = document.getElementById('hp');
//we bind our button to its own variable
const rollForHp = document.getElementById('rollForHealth');
//create an eventlistener and bind it to the button
rollForHp.addEventListener('click', healthRoll, false);
/*
This function will bind prompt input to a variable and change
element inner HTML instead of refreshing the whole document
*/
function healthRoll() {
let result = prompt('What is your new HP value?');
hp.innerHTML = `HP: ${result}`
}
索引更改为2。

如果您需要抓取而不是测试,则可以使用请求来获取数据。下面的代码是如何从页面获取数据的示例。
import requests
import re
# Return header page(html) to get token and list key
response = requests.get("http://biggestbook.com/ui/catalog.html#/itemDetail?itemId=HERY4832YER01&uom=CT")
# Get token using regular expression
productRecommToken = re.search("'productRecommToken','(.+)'", response.text)[1]
# Get list of keys using regular expression
listKey = re.search("'listKey',\\['(.*?)'\\]", response.text)[1].split("','")
# Create header with token
headers = {
'Accept': 'application/json, text/plain, */*',
'Referer': 'http://biggestbook.com/ui/catalog.html',
'Origin': 'http://biggestbook.com',
'DNT': '1',
'token': productRecommToken,
'BiggestBook-Handle-Errors-Generically': 'true',
}
# Create parameters with list keys and search values
params = (
('listKey', listKey),
('uom', 'CT'),
('vc', 'n'),
('win', 'HERY4832YER01'),
)
# Return json with all details about product
response = requests.get('https://api.essendant.com/digital/digitalservices/search/v1/items',
headers=headers,
params=params)
data = response.json()
# Get items from json, probably could be more than one
items = data["items"]
# Iterate and get details you need. Check "data" to see all possible details you can get
for i in items:
print(i["manufacturer"])
print(i["description"])
print(i["actualPrice"])
# Get attributes
attributes = i["attributes"]
# Example hot you can get specific one attribute.
thickness = list(filter(lambda d: d['name'] == 'Thickness', attributes))[0]["value"]
# Print all attributes as name = value
for a in attributes:
print(f"{a['name']} = {a['value']}")
