Question

我正在尝试从此网站http://bepi.mpob.gov.my/index.php/en/summary-2/893-summary-2018.html上抓取信息做一些建模，但是硒似乎无法获取表，并且无法扩展表tr / td中的任何标签。

这是我的代码

  let genPdf = () => {
var doc = new jsPDF('l', 'pt');
doc.autoTable(cols,rowArray, {
  // Styling
  theme: 'striped', // 'striped', 'grid' or 'plain'
  styles: {overflow: 'linebreak',columnWidth: 'wrap',lineWidth: 1,cellPadding: 2, fontSize: 10 },   
  columnStyles: { text: { columnWidth: 'auto' } },
  headerStyles: {},
  bodyStyles: {},
  alternateRowStyles: {},

  // Properties
  startY: 30, // false (indicates margin top value) or a number
  margin: 40, // a number, array or object
  pageBreak: 'auto', // 'auto', 'avoid' or 'always'
  tableWidth: 'auto', // 'auto', 'wrap' or a number, 
  showHeader: 'everyPage', // 'everyPage', 'firstPage', 'never',
  tableLineColor: 200, // number, array (see color section below)
  tableLineWidth: 0,

  // Hooks

});

doc.setPage(1 + doc.internal.getCurrentPageInfo().pageNumber - doc.autoTable.previous.pageCount);
doc.save('reporte.pdf');}

Answer 1

通过使用requests来获取iframe网址，然后使用pandas来获取该网址上的表格，您可以更快地完成操作

import pandas as pd
import requests 
from bs4 import BeautifulSoup

res = requests.get('http://bepi.mpob.gov.my/index.php/en/summary-2/893-summary-2018.html')
soup = BeautifulSoup(res.content, 'lxml')
iframeURL = soup.select_one('iframe')['src']
results = pd.read_html(iframeURL)
df = results[0].fillna('')
df.iloc[0][0] = 'Category'
print(df)

Answer 2

要检索标签内容，必须为文本为 Summary 2018 的元素引入 WebDriverWait 才能单击，并且可以使用以下解决方案：

代码块：

from selenium import webdriver
from bs4 import BeautifulSoup
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

options = webdriver.ChromeOptions()
# options.add_argument('headless') # older webdriver versions
options.set_headless(True) # newer webdriver versions
driver = webdriver.Chrome(chrome_options= options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
url = 'http://bepi.mpob.gov.my/index.php/en/summary-2.html'
driver.get(url)
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.LINK_TEXT, "Summary 2018"))).click()
soup = BeautifulSoup(driver.page_source, "html.parser")
print (soup)

但是，如果要检索表内容，则必须切换到框架并生成 WebDriverWait ，并且可以使用以下解决方案：

代码块：

from selenium import webdriver
from bs4 import BeautifulSoup
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

options = webdriver.ChromeOptions()
# options.add_argument('headless') # older webdriver versions
options.set_headless(True) # newer webdriver versions
driver = webdriver.Chrome(chrome_options= options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
url = 'http://bepi.mpob.gov.my/index.php/en/summary-2.html'
driver.get(url)
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.LINK_TEXT, "Summary 2018"))).click()
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"blockrandom")))
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//font[contains(.,'SUMMARY OF THE MALAYSIAN OIL PALM INDUSTRY  2018')]"))).click()
soup = BeautifulSoup(driver.page_source, "html.parser")
print (soup)

控制台输出：
