使用美丽的汤在标签中获取特定字符串<div>

标签。

我有一个标签列表，我提取的:

soup.findAll('div', {'class': 'formelement'}):

输出是:

[<div class="formelement">
<label class="libelle" for="field_tit">Etat :</label>
Publié              </div>,
<div class="formelement">
<label class="libelle" for="field_tit">Type de produit :</label>
Plaque de plâtre                </div>,
<div class="formelement">
<label class="libelle" for="field_tit">Numéro :</label>
PP/48-05                                    </div>,
<div class="formelement">
<label class="libelle" for="field_tit">Titulaire :</label>
CIA ESPAÑOLA DE AISLAMIENTOS SA             </div>,
<div class="formelement">
<label class="libelle" for="field_ref">Usine :</label>
39              </div>,
<div class="formelement">
<label class="libelle" for="field_tit">Date d'admission :</label>
13/07/2017                      </div>,
<div class="formelement">
<label class="libelle" for="field_tit">Date de reconduction :</label>
04/02/2021                      </div>,
<div class="formelement">
<label class="libelle" for="field_tit">Date de fin de validité :</label>
04/05/2022                      </div>,
<div class="formelement">
<label class="libelle" for="field_tit">Certificat PDF :</label>
<a href="application/docs/certificats/for div in soup.findAll('div', {'class': 'formelement'}):
product_data[div.text] = div.next_sibling
8_05.pdf" target="_blank">
<img src="public/images/pdf.gif" title="Télécharger le certificat au format PDF"/>
</a>
</div>]

我的目标是有一个字典:

product_data = {
"Numéro": "PP/48-05",
"Titulaire": "CIA ESPAÑOLA DE AISLAMIENTOS SA",
"Usine": "39",
"Date de fin de validité": "04/05/2022",
"Certificat PDF": "application/docs/certificats/PP_48_05.pdf"
}

I tried with

PP_4，但它将在标签内的所有字符串(显然)，并没有找到任何方法分别获得div内的两个字符串。如何分别得到这些字符串?

我希望我的问题足够明确。

可以销毁/分解内部标签

from bs4 import BeautifulSoup

输出
