title: OSX sed regex removal
body: <p>I am trying to remove a string from a grep search, and I can't seem to get sed to work, despite the regex appearing to be correct. I am also using OSX, but I installed gnu-sed to make things a little easier.</p>
  
  <p>I was hoping the following regex would remove all min certainties from :</p>
  
  <pre><code>gsed -r 's/minCertainty=\"\d\.\d{1,}\"//g'
  </code></pre>
  
  <p>Here is an example of the text I am dealing with, for context:</p>
  
  <pre><code>&lt;vendor="company1" minCertainty="1.0"/&gt;
  &lt;vendor="company2" minCertainty="0.75"/&gt;
  &lt;vendor="company3" minCertainty="0.25"/&gt;
  </code></pre>
