Supprimer les balises BeautifulSoup d'une liste en Python

Question

J'ai le code suivant qui passe par une liste et extrait des informations à mettre dans une nouvelle liste.

Si un 0 est trouvé, un 0 est ajouté. Si un 'None' est trouvé, un 0 est ajouté. Le troisième type d'élément de liste est une balise extraite de BeautifulSoup.

Ce que je veux être en mesure de faire est extrait des informations de l'intérieur l'étiquette et append que l'étant donné que je travaille cependant newList, avec un regex les informations contenues dans l'étiquette devient de la manière .

Le code que j'ai est donnée ici:

list = ['<a class="vote-description__evidence" href="/mp/10001/diane_abbott/hackney_north_and_stoke_newington/divisions?policy=826">11 votes for, 1 vote against, 15 absences, between

newList = []

aggregate = 0 
    if thing == '0':

     againstNum = int(matches[1]) 
     aggregate = forNum - againstNum 
     newList.append(aggregate) 
print newList 
print len(newList) 

Le problème est que l'étiquette elle-même a des chiffres en elle, qui se débarrassant de la valeur de l'agrégat.

Habituellement, je voudrais juste changer le code pour dire int(matches[2]) et int(matches[3]); Cependant, cela n'est pas fiable car je vais exécuter ce code sur des listes différentes et le nombre de correspondances dans le tag lui-même changera.

Existe-t-il un moyen de supprimer les balises de la liste avant que les correspondances soient trouvées?

Answer 1

Pour extraire le texte à l'intérieur de chaque étiquette à l'aide Beautiful Soup vous pouvez le faire:

aggregate = 0 
for thing in list: 
    if thing == '0': 
     newList.append(0) 
    elif thing == 'None': 
     newList.append(0) 
    else: 
     matches = re.findall(digitReg, BeautifulSoup(thing,'html.parser').text) 
     againstNum = int(matches[1]) 
     aggregate = forNum - againstNum 
     newList.append(aggregate)
