There is a page i want to parse in lxml，the table data will change into different form when you click on.
from urllib.request import urlopen
import lxml.html
url="http://f10.eastmoney.com/f10_v2/FinanceAnalysis.aspx?code=sz300059"
material=urlopen(url).read()
root=lxml.html.parse(material)
if i write,
set=root.xpath('//table[@id="BBMX_table"]//tr')
i get the table data of the corresponding of
<li class="first current" onclick="ChangeRptF10AssetStatement('30005902','8','All',this,'');">
what i get is :
what i want to get the table data is the corresponding of
<li class="" onclick="ChangeRptF10AssetStatement('30005902','8','Year',this,'');">
what i want to get is:
how can i write my xpath expression root.xpath properly ?more info:when you click on 按年度,the table will change into other one .onclick="ChangeRptF10AssetStatement('30005902','8','Year',this,'')
I have tried with selenium:
import lxml
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument("--headless")
browser = webdriver.Chrome(options=chrome_options,executable_path='/usr/bin/chromedriver')
browser.get("http://f10.eastmoney.com/f10_v2/FinanceAnalysis.aspx?code=sz300059")
root = lxml.html.document_fromstring(browser.page_source)
mystring = lxml.etree.tostring(root, encoding = "unicode")
with open("/tmp/test.html","w") as fh:
fh.write(mystring)
Open /tmp/test.html ,no data in it,how can i get my expect data?

Here is HTML you get using your code, table is inside a script tag :
<script type="text/template" id="tmpl_zyzb">
{{if (zyzb==null||zyzb.length<=0)}}
<div>
暂无数据
</div>
{{else}}
<table>
<tbody>
<tr>
<th class="tips-colname-Left">
<span>每股指标</span>
</th>
{{each zyzb as value i}}
<th class="tips-fieldname-Right" data-value="{{value.date}}">
<span>{{value.date.substr(2,8)}}</span>
</th>
{{/each}}
</tr>
To use Selenium you need to wait for page to be loaded. In the code below you can find example with WebDriverWait:
from selenium.webdriver.support.ui import WebDriverWait
browser.get("http://f10.eastmoney.com/f10_v2/FinanceAnalysis.aspx?code=sz300059")
WebDriverWait(browser, 10).until(lambda d: d.execute_script(
'return ["complete", "interactive"].indexOf(document.readyState) != -1'))
root = lxml.html.document_fromstring(browser.page_source)
print(root.xpath("//*[@class='name']//strong")[0].text)
print(root.xpath("//div[@id='report_zyzb']//th//span")[0].text)
You can get information for all tables in the page using API requests. Each tab of the first 主要指标 section's table has one URL with different type(0, 1 and 2) parameters. Same approach work for other tables also:
import requests
headers = {
'Connection': 'keep-alive',
'Pragma': 'no-cache',
'Cache-Control': 'no-cache',
'Accept': '*/*',
'DNT': '1',
'X-Requested-With': 'XMLHttpRequest',
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36',
'Referer': 'http://f10.eastmoney.com/f10_v2/FinanceAnalysis.aspx?code=sz300059',
'Accept-Encoding': 'gzip, deflate',
'Accept-Language': 'ru,en-US;q=0.9,en;q=0.8,tr;q=0.7',
}
# Section: 主要指标
section_url = 'http://f10.eastmoney.com/NewFinanceAnalysis/MainTargetAjax'
data_code = 'SZ300059'
with requests.Session() as s:
# 按报告期
data_type = 0
response = s.get(f'{section_url}?type={data_type}&code={data_code}', headers=headers, verify=False)
print(response.text)
# 按年度
data_type = 1
response = s.get(f'{section_url}?type={data_type}&code={data_code}', headers=headers, verify=False)
print(response.text)
# 按单季度
data_type = 2
response = s.get(f'{section_url}?type={data_type}&code={data_code}', headers=headers, verify=False)
print(response.text)
Json response (formatted):

When you crawl a website, it can cause unwanted consequences.
Make sure the site you are crawling does not prohibit you from doing so. If they say don't crawl the website, you should respect that.
I see in your code that use selenium and output html file:
UPDATE: Desiring to create stable code to work, according to Sers's suggestion that: should optimize the method of waiting for the website element has finished loading. I adjusted the code as follows:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
import time
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument("--headless")
browser = webdriver.Chrome(options=chrome_options,
executable_path=r'F:\chromedriver.exe')
wait = WebDriverWait(browser, 20)
list_stock = ['sz300059', 'sz300766', 'sz002950']
try:
for id_stock in list_stock:
url_id = "http://f10.eastmoney.com/f10_v2/FinanceAnalysis.aspx?code=" + id_stock
browser.get(url_id)
# click to element 按年度 (Per year)
wait.until(lambda e: e.execute_script('return document.readyState') != "loading")
wait.until(EC.presence_of_all_elements_located([By.CSS_SELECTOR, "#zyzbTab > li:nth-child(2)"]))
element_per_year = browser.find_element_by_css_selector('#zyzbTab > li:nth-child(2)')
element_per_year.click()
# get table
wait.until(lambda e: e.execute_script('return document.readyState') != "loading")
wait.until(EC.presence_of_all_elements_located([By.CSS_SELECTOR, "#report_zyzb"]))
# time.sleep(5)
element_tb_per_year = browser.find_element_by_css_selector('#report_zyzb')
tb_per_year_html = element_tb_per_year.get_attribute('innerHTML')
path_file_html = fr'F:\test_{id_stock}.html'
with open(path_file_html, "w", encoding='utf-8') as fh:
fh.write(tb_per_year_html)
print(f'export id: {id_stock}')
except TimeoutException:
print("Timed out waiting for page to load")
finally:
browser.close()
browser.quit()
When WebDriverWait works incorrectly, I think you should use time.sleep. You can google more information about this.
