title: How to get all article pages under a Wikipedia Category and its sub-categories?
body: <p>I want to get all the articles names under a category and its sub-categories. </p>
  
  <p>Options I'm aware of:</p>
  
  <ol>
  <li>Using the Wikipedia API. Does it have such an option??</li>
  <li>d/l the dump. Which format would be better for my usage? </li>
  <li>There is also an option to search in Wikipedia something like <code>incategory:"music"</code>, but I didn't see an option to view that in XML.</li>
  </ol>
  
  <p>Please share your thoughts</p>
