I want to scrap content from a webpage,the content is encapsulated in the <div> with ID valued 'content',now,I retrieve every paragraph enclosed with <p>,there are actually another tag <figure> in the div,finally I got results with both <p> And <figure>,<figure> should not be there and what is wrong with me?

DOM structure

div id= content p p figure p figure p p div

Answer 1

Would this work?

$res = $html->find('#content p');
