title: Eclipse ADT - Error parsing XML: not well-formed (invalid token)
body: <p>I have an array of 9 buttons, in 3 sets of 3. The sets formed by a Horizontal Linear Layout, and the 3 sets come together to form the array of 9 buttons in a parent Vertical Linear Layout.</p>
  
  <p>The error appears at the first button opening tag, and says "Error parsing XML: not well-formed (invalid token)".</p>
  
  <p>I think the problem might be in the opening and closing tags for the LinearLayout, but I've checked multiple times to make sure that they are correct, and I'm pretty sure that they are. I'm not sure what else could be causing the problem.</p>
