Question

我试图仅从列表中获取显示的文本，但是我一直在找回链接文本的工具提示。

如何更改此设置，以便获得

'1/2 lemon, zested'

代替

'½ lemon, zested Lemon le-monOval in shape, with a pronouced bulge on one end, lemons are one of the most versatile fruits...'

有什么想法吗？

ingredients = ingredientsBlock.findAll('li', class_='ingredients-list__item')

print(ingredients[3].text)

Answer 1

您似乎只想要content属性。可以这样完成：

soup = BeautifulSoup(html, "html.parser")
ingredientsBlock = soup.find('div', class_='ingredients-list__content')

for ingredient in ingredientsBlock.find_all('li', class_='ingredients-list__item'):
    print(ingredient['content'])

然后将成分显示为：

225g softened butter
225g golden caster sugar
4 large eggs
½ lemon, zested
1 tsp vanilla extract
225g self-raising flour
splash of milk
Optional fillings of lemon curd, jam, lightly whipped cream
icing sugar for dusting
