CSS：for循环中的第n个类型不提取文本

Question

我想从 10 个div class = col-12 的 每个 的 3 个子级中的每个子级中提取字符串 text_i_wantA、text_i_wantB、text_i_wantC。为了可读性，我只包含了两个相同的结构化 div。现在我很好，如果它没有返回实际的.content[0]，因为我也可以稍后解析它。

这里是完整的代码：

title,date,name,number = [],[],[],[]
while True:
    soup = bs(driver.page_source, 'html5lib')
    for div in soup.find_all('a', attrs={'title':'ad i'}):
        titl = div.get_text(strip=True)
        title.append(titl)
    else:
        break
    for col in soup.find_all('div', attrs={'class':'col-12'})[1::2]:
        row = []
        for entry in col.select('div.row div'):
            target = entry.find_all(text=True, recursive=False)
            row.append(target[0].strip())
        name.append(row[0])
        date.append(row[1])
        number.append(row[2])  

    next_btn = driver.find_elements_by_css_selector(".page-next button")
    if next_btn:
        actions = ActionChains(driver)
        actions.move_to_element(next_btn[0]).click().perform()
        time.sleep(4)
    else:
        break
driver.close()

预期输出：

title = ["text_i_already_have1", "text_i_already_have2", ...]

date = ["text_i_wantA", "text_i_wantAA", ...]

name = ["text_i_wantB", "text_i_wantBB", ...]

number = ["text_i_wantC", "text_i_wantCC", ...]

问题：实际输出with slice [1::2]

title = ["text_i_already_have1", "text_i_already_have2", ...]
date = ['text_i_wantA', 'text_i_wantAA', ...],
name = ['', '', '', '', '', '', '', '', '', '']
number = ['', '', '', '', '', '', '', '', '', '']

是我的 CSS 还是循环本身的问题？

第一行工作正常： print(soup.find_all('div', attrs={'class':'col-12'})) without slice 给了我想要从以下位置提取 text_i_want 的 div 列表：

[<div class="col-12">
                            <a href="/url" target="_blank" title="ad i">
                                text_i_already_have1
                            </a>
                        </div>, 
                  <div class="col-12">
                            <div class="row">

                                    date: text_i_wantA

                            </div>

                                    <div>
                                        source: text_i_wantBBB

                 <div class="col-12">
                            .  
                            . 
                            . 
                            . 
                        </div>]

text_i_dont_want 始终位于 <span class="processlink"> 元素内，该元素本身是 10_per_page <div class="col-12"> 元素中的每一个内的 3 个 <div class="row"> 元素之一的最后一个子元素。

Answer 1

如果我现在对您的理解正确，这应该可以让您到达那里（或至少足够接近）：

date,name,number = [],[],[]
for col in soup.find_all('div', attrs={'class':'col-12'}):
    row = []
    for entry in col.select('div.row div'):
        target = entry.find_all(text=True, recursive=False)
        row.append(target[0].strip())
    date.append(row[0])
    name.append(row[1])
    number.append(row[2])   

例如print(date) 的输出应该是：

['text_i_wantA', 'text_i_wantAA']
