【问题描述】:
我想提取下面p标签内的内容。
<section id="abstractSection" class="row">
<h3 class="h4">Abstract<span id="viewRefPH" class="pull-right hidden"></span>
</h3>
<p> Variation of the (<span class="ScopusTermHighlight">EEG</span>), has functional and. behavioural effects in sensory <span class="ScopusTermHighlight">EEG</span We can interpret our. Individual <span class="ScopusTermHighlight">EEG</span> text to extract <span class="ScopusTermHighlight">EEG</span> power level.</p>
</section>
一行Selenium如下,
document_abstract = WebDriverWait(self.browser, 20).until(
EC.visibility_of_element_located((By.XPATH, '//*[@id="abstractSection"]/p'))).text
可以轻松提取p标签内容并提供如下输出:
Variation of the EEG, has functional and. behavioural effects in sensoryEEG. We can interpret our. Individual EEG text to extract EEG power level.
不过,出于速度考虑,我想使用BeautifulSoup。
通过引用css选择器(即#abstractSection)测试了以下bs
url = r'scopus_offilne_specific_page.html'
with open(url, 'r', encoding='utf-8') as f:
page_soup = soup(f, 'html.parser')
home=page_soup.select_one('#abstractSection').next_sibling
for item in home:
for a in item.find_all("p"):
print(a.get_text())
但是,编译器返回以下错误:
AttributeError: 'str' 对象没有属性 'find_all'
此外,由于Scopus 需要登录ID,因此可以使用通过link 访问的离线html 来重现上述问题。
请问我哪里做错了,感谢任何见解
