title: Extract a file from a ZIP string
body: <p>I have a BASE64 string of a zip file that contains one single XML file.</p>
  
  <p>Any ideas on how I could get the contents of the XML file without having to deal with files on the disk? </p>
  
  <p>I would like very much to keep the whole process in the memory as the XML only has 1-5k. </p>
  
  <p>It would be annoying to have to write the zip, extract the XML and then load it up and delete everything.</p>
