Python-无法将刮擦XML文件（从sec.gov）的结果转换为RAW字节

Question

我正在尝试从sec.gov刮擦XML文件，然后将其转换为一个长字符串，但是它只是返回一堆字符串的一堆地址，我不知道如何将其作为字符串返回，或可以转换为字符串的对象。

例如，我只想要一个字符串形式：

<?xml version="1.0" encoding="ISO-8859-1" ?>
  <feed xmlns="http://www.w3.org/2005/Atom">
    <author>
      <email>[email protected]</email>
      <name>Webmaster</name>
    </author>
    <company-info>
      <addresses>
        <address type="mailing">
          <city>CHATHAM</city>
          <state>NJ</state>
          <street1>26 MAIN STREET, SUITE 101</street1>
          <zip>07928</zip>
        </address>
        <address type="business">
          <city>CHATHAM</city> 

这是我的代码：

#!/usr/bin/python3

from lxml import html
from lxml import etree
import requests
from time import sleep
import json
import argparse
from random import randint
import sys
from urllib.parse import urlencode
from urllib.request import Request, urlopen
from pprint import pprint
import traceback
from xml.etree import ElementTree


def parse_finance_page(urlAddress):

  headers = {
          "Accept-Encoding":"gzip, deflate",
          "Accept-Language":"en-GB,en;q=0.9,en-US;q=0.8,ml;q=0.7",
          "Connection":"keep-alive",
          "Cache-Control":"no-store, no-cache, must-revalidate, max-age=0'",
          "Cache-Control":"post-check=0, pre-check=0",
          "Pragma":"no-cache",
          "Host":"www.sec.gov",
          "Referer":"https://www.sec.gov",
          "Upgrade-Insecure-Requests":"1",
          "User-Agent":"[email protected]"
    }

  for retries in range(5):
    try:

      request = Request("https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001430306&type=&dateb=&owner=include&start=0&count=40&output=atom", headers=headers)
      html = urlopen(request).read()

      print(html)
  
      xmlString = ElementTree.tostring(html, encoding='unicode')
      print(xmlString)

      quit() 

第一个打印只是打印出看起来像一堆内存地址的字节字符串，例如：

b'\ x1f \ x8b \ x8b \ x08 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00 \ x00 \ x03 \ xed \ x9dko \ xdb8 \ x16 \ x16 \ x86 \ xbf \ xbf \ xaf \ xaf \ xf \ xf2a0 x9d＆amp; 3 \ xbb \ x8b \ xc5b \ xa0 \ xd8t“ \ xd4 \ x96 \ x0cin \ x92 \ x92 \ xf9 h \ xbc \ x1c \ x9d \ xfc \ xfc0 \ x9d \ xa0 \ xaf，\ x8a \ xfd0 \ xe8 \ x1d \ x1d \ x91c | \ x84x0 \ x84x0 \ x0cg〜p \ xdb; xf4s \ xffo \ x08 \ x9d \ x8c \ x19 \ x1b！ x8c \ x8d \ xee \ t \ xa7gp \ x99w \ xf7 \ xe6 \ xc9] \ x18 \ xa5o \ xf8 [6 \ xf5 \ xfci \ xfci \ xfci \ xff \ x9e x9et \ xd3 \ x0f \ x16 \ xd5 \ x02o \ xca \ xfa \ xfa \ xffz \ xd4：\ xe9 \ x8a \ xf7 \ xf7 \ xe9 \ xe9 \ x01 \ x01 \ xbb \ xbb \ xeb \ xebg＆lt; c <代码> \ x1c。\ xbf \ xed \ x8df \ x11 \ x8bc \ x16/jve（y \ x9c \ xb1 \ xde \ xde \ x11 \ x11 \ xfc \ x18？ r \ xae \ xdf \ rn \ xba \ Xe2 \ xdd \ xfa \ xc7q \ xc7q \ xe2％\ xac \ x7f \ x7f \ xf9 \ xcbi7} \ xf5 \ xf5 \ xf5 \ xf5 \ xb3 \ xb3 \ x88 \ x88 \ x88 \ xb1 \ x89 \ x84 \ x84 \ x84 \ x84 \ x84 \ x84 \ x f \ Xe7 \ X97 \ Xe8 \ Xea \ Xfa \ Xf3 \ Xd9 \ Xd9 \ Xd9 \ Xf5+T \ Xf5 \ Xdb \ Xdb \ Xf9 \ Xf9 \ Xf5 \ X19 \ X19“ \ xb1 \ xe5p \ xfb \ xa4 \ x0b/w \ xad \ xedf \ xcd} \ xf6 \ xf6 \ x04n \ xe6 \ xb1 \ xb1 \ x1f \ x1f \ x1f \ xf \ xf0 \ xb7 \ xed86 \ xee8 \ xc40n \ xbaiys \ xcesy \ xb0 \ xea \ xbb \ xbb \ x13/\ x8e \ xfd \ xfd \ xdb \ x80 \ x80 \ x80 \ x80 \ x8d：\ xb1：\ xb1？ \ x8b \ x87 \ xfdo \ xef \ x06 \ x9f/\ x06 \ xa7g \ xbf \ xbf] \ x9f \ x9f \ x9f \ x0e＆gt; \ xa0o \ x90o \ x9f \ x9f \ x9f

而且它不断地...

线：

xmlString = ElementTree.tostring(html, encoding='unicode')
print(xmlString)

只是生产：

Failed to process the request, Exception:'bytes' object has no attribute 'iter'

任何帮助都将受到极大的赞赏。
