如何提取精确的 CSS 选择器

Question

我正在尝试使用 Beautifulsoup 和精确匹配的 CSS 选择器从 div 中提取。

我已经阅读了a link 的帖子 并发布 a link ，但他们没有解决我的问题。

我要提取的div只有以下几种：

<div class="s-suggestion" data-alias="aps" data-crid="3LY5DQXGQLBAV" data-isfb="false" data-issc="false" data-keyword="aa batteries" data-nid="" data-reftag="nb_sb_ss_i_3_1" data-store="" data-type="a9" id="issDiv2"><span class="s-heavy"></span>a<span class="s-heavy">a batteries</span></div>

它们必须包含：data-alias="aps" 而不仅仅是 data-alias=（因为还有许多其他具有其他属性的 div，例如 data-alias="gift-cards" 等。

这是我尝试过的代码。

from selenium import webdriver
from bs4 import BeautifulSoup
import time

browser = webdriver.Chrome('chromedriver.exe')
mainUrl = "https://www.amazon.com/"
browser.get(mainUrl)
mainSoup = BeautifulSoup(browser.page_source, "html.parser")
searchInput = browser.find_element_by_xpath('//input[@id="twotabsearchtextbox"]')
searchInput.clear()
searchInput.send_keys('a')
time.sleep(2)
searchSoup = BeautifulSoup(browser.page_source, "html.parser")
searchResult = searchSoup.find_all('div', attrs={'id': 'suggestions-template'})
keys = searchSoup.select('div[data-alias]')
for key in keys:
    print(key)

这是我得到的结果：

<div class="s-suggestion" data-alias="aps" data-crid="3LY5DQXGQLBAV" data-isfb="false" data-issc="false" data-keyword="amazon gift cards" data-nid="" data-reftag="nb_sb_ss_i_1_1" data-store="" data-type="a9" id="issDiv0"><span class="s-heavy"></span>a<span class="s-heavy">mazon gift cards</span></div>

我也尝试将汤替换为：

keys = searchSoup.select('div[data-alias]="aps"')

但我收到此错误：

SyntaxError: Invlaid character '=' at position 15

我如何专门获取：data-alias="aps" div？ 谢谢

问题解决了，我把引号“”放在了错误的位置，这是正确的位置：

keys = searchSoup.select('div[data-alias="aps"]')
