python - 如何抓取 - 跨 aria-hidden ="true"- 文本

Question

 <div class="comments-post-meta__profile-info-wrapper display-flex">
    <a class="app-aware-link  inline-flex overflow-hidden t-16 t-black t-bold tap-target" target="_self" href="https://www.linkedin.com/in/ACoAAAAg-vkBuoZD8xeJW57GlPMiPRWUe-jvvSM" data-test-app-aware-link="">
      <h3 class="comments-post-meta__actor display-flex flex-column overflow-hidden t-12 t-normal t-black--light">
        <span class="comments-post-meta__name text-body-small-open t-black">
          <span class="comments-post-meta__name-text hoverable-link-text mr1">
            <span dir="ltr"><span aria-hidden="true"><!---->Nathan Greenhut<!----></span>
            <span class="visually-hidden"><!---->View Nathan Greenhut’s profile<!----></span>
          </span>
        </span>
</div>

我正在尝试抓取对特定 LinkedIn 帖子发表评论的人员的姓名。

我尝试了这段代码:

for i in soup.find_all("span",attrs = {"class" : "comments-post-meta__name-text hoverable-link-text mr1"}):
    print(i.find('span').get_text())

我得到的输出是:

Nathan GreenhutView Nathan Greenhut’s profile

但我想要的输出是:

Nathan Greenhut

您可以直接通过元素的属性来选择元素:

soup.find('span', {'aria-hidden': 'true'}).get_text(strip=True)

或通过css selector

soup.select_one('[aria-hidden="true"]').get_text(strip=True)

或者如果有其他元素具有更具体的此类属性:

soup.select_one('.comments-post-meta__profile-info-wrapper [aria-hidden="true"]').get_text(strip=True)
