title: Extracting specific numerical values
body: <p>I have data of the following form:</p>
  
  <pre><code>&lt;A&gt;  &lt;pred&gt;       "7630000.0"^^&lt;m^2&gt; .
  &lt;R&gt;     &lt;pred&gt;       "2150000.0e11"^^xsd:integer .
  &lt;G&gt;      &lt;pred&gt;       "5.85E7"^^&lt;/km^2&gt; .
  &lt;T&gt;   &lt;pred&gt;       "4810000.0"^^&lt;http://www.w3.org/2001/XMLSchema#nonNegativeInteger&gt; .
  &lt;Y&gt;   "this 18"       "1.863E8"^^&lt;s&gt; .
  &lt;D&gt;      &lt;pred&gt;       "2023428.2112e09"^^&lt;&gt; .
  &lt;GS&gt;   &lt;wd&gt;     "760mm"^^&lt;en&gt; .
  &lt;Vi&gt;       &lt;hasIn&gt;  "13.89"^^&lt;%&gt; .
  </code></pre>
  
  <p>Now I want to extract all numerical values within the last quotes and store them into a file. Note, that here I want to leave all non-numerical values e.g. "760mm". For example for the above example, I want to extract the following numerical values:</p>
  
  <pre><code>7630000.0, 2150000.0e11, 5.85E7, 4810000.0, 1.863E8, 2023428.2112e09, 13.89, 
  </code></pre>
  
  <p>I tried doing the same by splitting on " but by doing so I end up getting 18 also which I do not want. Is there some way in python or using linux commands by which I may achieve the same.</p>
