使用正则表达式提取第 2、3、4 等匹配项

Question

:)

I am a very noob regex user and I am trying to extract the content of every line, exactly the content of ingredient-data , which will be wheat flour for first line, white sugar for the second, and so on.

I usually extract stuff using (.*?) but this matches all the results and I need different regex to match all of them separately to extract all of the results by separate.

Thanks <3

<ul>
  <li ingredient-data="wheat flour">1 cup wheat flour</li>
  <li ingredient-data="white sugar">3 tablespoons white sugar</li>
  <li ingredient-data="baking powder">2 teaspoons baking powder</li>
  <li ingredient-data="baking soda">½ teaspoon baking soda</li>
  <li ingredient-data="salt">½ teaspoon salt</li>
</ul>

You should have some success with what you're already using if you can match what you need already.

For example the regex ingredient-data="(?P<ingredient>.*?)" will match all the results, and then you should be able to iterate through the matches to process each result separatly.

If that's not exactly what you're asking, could you provide a little more context and some code?
