title: How to remove single attribute with quotes via RegEx
body: <p>I am trying to match an attribute to I can do a search/replace. I am having trouble though because it is matching beyond the quotes of the attribute I want. For example, I want to remove xref="..." from here:</p>
  
  <pre><code>&lt;a href="page.ashx" xref="somethingelse" title="something" class="image"&gt;
  </code></pre>
  
  <p>But when I do a RegEx like this: xref=\".*\", then it selects the attributes xref, title, AND class. How do I tell it to only select the xref attribute?</p>
