Get text with BeautifulSoup CSS Selector

问题

Example HTML

<h2 id="name">
    ABC
    <span class="numbers">123</span>
    <span class="lower">abc</span>
</h2>

I can get the numbers with something like:

soup.select('#name > span.numbers')[0].text

How do I get the text ABC using BeautifulSoup and the select function?

What about in this case?

<div id="name">
    <div id="numbers">123</div> 
    ABC
</div>

回答1:

In the first case, get the previous sibling:

soup.select_one('#name > span.numbers').previous_sibling

In the second case, get the next sibling:

soup.select_one('#name > #numbers').next_sibling

Note that I assume that it is intentional that here you have the numbers as an id value and the tag is div instead of span. Hence, I've adjusted the CSS selector.

To cover both cases, you can go to the parent of the tag and find the non-empty text node in a non-recursive mode:

parent = soup.select_one('#name > .numbers,#numbers').parent
print(parent.find(text=lambda text: text and text.strip(), recursive=False).strip())

Note the change in the selector - we are asking to match either numbers id or numbers class.

Though, I have a feeling that this universal solution would not be quite reliable because, for starters, I don't know what your real inputs could be.
