title: How do I programmatically apply a Drupal input filter?
body: <p>I am currently exporting Drupal data to an external source (XML) programmatically. However, I want the data to run through the site's default Input Format (the filter that runs before user content is displayed on the website) before being written to file.</p>
  
  <p>How do I programmatically apply a Drupal input filter? Is there a specific function call or hook for this purpose? If so, links/advice would be most appreciated.</p>
