我已经搜索了高低的答案,但似乎并不是一个明确的解决方案。这是:
from selenium import webdriver
chromedriver_path = ("localchromedrive/chromedriver.exe")
chromeOptions = webdriver.ChromeOptions()
MSCI_dir = ("mylocaldrive")
prefs = {"download.default_directory" : MSCI_dir}
chromeOptions.add_experimental_option("prefs", prefs)
driver = webdriver.Chrome(chromedriver_path,chrome_options=chromeOptions)
url = "https://www.ishares.com/us/239637/fund-download.dl"
driver.get(url)
该文件现在以本地路径下载并保存为以下内容:
temp_path = "mylocaldrive\iShares-MSCI-Emerging-Markets-ETF_fund.xls"
此文件保存为" .xls"文件类型,但它显然是一个XML文件。请参阅下面的NotePad中打开的文件。
我试过xlrd:
import xlrd
book = xlrd.open_workbook(temp_path)
XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'\xef\xbb\xbf<?xml'
我已尝试过xml.etree:
import xml.etree.ElementTree as ET
tree = ET.parse(temp_path)
File "<string>", line unknown
ParseError: mismatched tag: line 16, column 2`
我尝试过xlwings:
wb = xw.Book(temp_path)
wb.save(xlsx_path)
wb.close()`
看起来很有效,但是当我尝试使用pandas时,我得到了这个:
pd.read_excel(xlsx_path)
XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'\xef\xbb\xbf<?xml'`
我尝试过BeautifulSoup
from bs4 import BeautifulSoup`
soup = BeautifulSoup(open(temp_path), "xml")`
In [1]: soup
Out[1]: <?xml version="1.0" encoding="utf-8"?>`
In [2]: soup.contents
Out[2]: []`
In [3]: soup.get_text()
Out[3]: ''`
我正在寻找使用pandas访问此文件的权威方法。让我知道你需要的我缺少的信息。
答案 0 :(得分:0)
我认为您的问题是该文件不是XLS,而是XLSX文件,它是Microsoft为减少DOC和XLS文件大小而制作的特殊XML文件。
