I am trying to web scraping using this tutorial : https://medium.com/@roymilaniitd/web-scraping-to-extract-news-using-matlab-dd78b954684 , But when I test the following code:

html = webread('https://www.indiatoday.in/top-stories');
list = extractBetween(html,'<h3 class=”” title=','</a></h3><p>');
list2=extractAfter(list,'<a href="');
list3 = extractAfter(list2,'">');

I get the contents in a html char variable, but three 0*1 cells list1, list2, list3!

Why this happens?

在 MATLAB Online 中打开

You are searching for:

'<h3 class=”” title='
%          ^^

I'm sure, you mean:

'<h3 class="" title='

with standard double quotes ".

The author of this page seems to use a tool like MS Word to create webpages and let the automatic replacement insert smart quotes. This is a very bad idea when posting code in the internet.
