XML parsing failed: junk after document element (Line: 8, Character: 2)

<div class="node">
    <h2 class="sifr-node-title">
    <a href="" title=""></a>
 </h2>
    <div class="content"></div>
    </div>
  
/*It doesn't seem to like the open tag below (<) right before ?xml. That's the only error it points to. What's going on? Thanks!
