title: extract table values form curl output
body: <p>I'm trying to extract random values that proceed a unique string, the layout is</p>
  
  <pre><code>&lt;tr&gt;&lt;td&gt;&lt;a&gt;uniquestring"&lt;/a&gt;&lt;/td&gt;
  &lt;td&gt;RANDOM NUMBER k/b&lt;/td&gt;
  &lt;td&gt;RANDOM NUMBER&lt;/td&gt;
  &lt;td&gt;RANDOM NUMBER&lt;/td&gt;
  &lt;td&gt;RANDOM NUMBER&lt;/tr&gt;
  </code></pre>
  
  <p>I want to do something like</p>
  
  <pre><code>curl -is http://webpage.com/ |grep uniquestring | echo RANDOM NUMBER k/b
  </code></pre>
  
  <p>I'd also like to return all values on a single line ie echo</p>
  
  <pre><code>uniquestring RANDOMNUMBER k/b RANDOMNUMBER RANDOMNUMBER RANDOMNUMBER
  </code></pre>
  
  <p>The page generates multiple 'blocks' of 5 the lines above and i'm only interested in obtaining the values that are after a specific uniquestring.</p>
