我正在尝试使用lxml来获取两个字段:iPhone和29,906。
这是更大的html文件的一部分。
我已经找到了如何在每个td中提取字体,但是我需要能够匹配iPhone字段和29906字段。
我能想到的一种方法是将所有内容放入一个很长的数组中并搜索“ iPhone”并返回iPhone + 2的值,但这似乎很漫长且效率低下。
有人可以引导我朝正确的方向吗?
这是我到目前为止所拥有的:
from bs4 import BeautifulSoup
import requests
from lxml import html, cssselect
link = "https://www.sec.gov/Archives/edgar/data/320193/000032019318000100/a10-qq320186302018.htm"
response = requests.get(link)
soup = BeautifulSoup(response.text, 'html.parser')
str_soup = str(soup)
doc = html.document_fromstring(str_soup)
for col in doc.cssselect('font'):
try:
style = col.attrib['style']
if style=="font-family:Helvetica,sans-serif;font-size:9pt;":
print(col.text.strip())
except:
pass
这将返回所有文本,但不是我需要的文本。

怎么样?
from bs4 import BeautifulSoup
import re
soup = BeautifulSoup(html, 'html.parser')
x = soup.find_all('font')
name = re.sub(r"[\n\t\s]*", "", x[0].get_text())
value = re.sub(r"[\n\t\s]*", "", x[3].get_text())
print(name, 'costs', value)
输出:
iPhone costs 29,906

我没有得到我想要的东西,但是到目前为止我可以提出来的东西是基于
from bs4 import BeautifulSoup
import requests
from lxml import html, cssselect
import csv
link = "https://www.sec.gov/Archives/edgar/data/320193/000032019318000100/a10-qq320186302018.htm"
response = requests.get(link)
soup = BeautifulSoup(response.text, 'html.parser')
str_soup = str(soup)
doc = html.document_fromstring(str_soup)
with open('AAPL_financials.csv', 'w') as csvfile:
writer = csv.writer(csvfile)
for col in doc.cssselect('tr'):
row = []
for text in col.cssselect('font'):
if text.text == None:
continue
value = text.text.strip()
if value == "":
continue
if value == "$":
continue
if value == "%":
continue
if value == ")":
continue
if value[0] == "(":
value = value.replace("(", "-"))
row.append(value)
writer.writerow(row)
