title: Using wildcards in getElementsByClassName
body: <p>I'm making a js function for a Chrome extension that replaces content in the Facebook newsfeed. Each post has the class <code>uiUnifiedStory uiStreamStory genericStreamStory aid_1719315288 uiListItem uiListLight uiListVerticalItemBorder</code> where <code>aid</code> always changes.</p>
  
  <p>If I want to get all the classes, I can't just use <code>aid_*</code>.</p>
  
  <p>How can I get all of the <code>li</code> elements that match the class <code>uiUnifiedStory uiStreamStory genericStreamStory aid_* uiListItem uiListLight uiListVerticalItemBorder</code> where aid can be anything. </p>
