  assert extract_info("<div class=\"data\"> <h1>Name: John Doe</h1> <h3>Age: 25</h3> <h3>Location: Los Angeles, CA</h3> </div>") == ('John Doe', '25', 'Los Angeles, CA')
  assert extract_info("<div class=\"data\"> <h1>Name: Jane Smith</h1> <h3>Age: 30</h3> <h3>Location: New York, NY</h3> </div>") == ('Jane Smith', '30', 'New York, NY')
  assert extract_info("<div class=\"data\"> <h1>Name: Alice Johnson</h1> <h3>Age: 22</h3> <h3>Location: Chicago, IL</h3> </div>") == ('Alice Johnson', '22', 'Chicago, IL')
