title: Convert regex from Python format to GNU Sed format
body: <p>I'm parsing a roughly 10GB log file, and need to feed it through sed to capture some output. The necessary capture segment based on what I would use in JavaScript is:</p>
  
  <pre><code>s/method=""([^"]*)"".*path=""([^"]*)"".*accept=""([^"]*)""/"\1","\2","\3"/
  </code></pre>
  
  <p>Unfortunately sed (GNU sed 4.2.1, GnuWin32 edition) is struggling over the <code>[^"]*</code> ranges. It refuses to match them. I've tried variations of other acceptance blocks, with <code>[a-zA-Z0-9:\\/.]*</code> and similar variants but there seem to always be new characters inside the block that it misses, and really I can accept any valid character held between the quotes. With sed's * routine being a greedy implementation it tends to also have problems on the final "accept" item, pulling in all the other items on the log entry right up until the end.</p>
  
  <p>I need to capture everything between the quotation marks and ignore the rest of the log entry.</p>
  
  <p>I've been at this for two days for some stupid thing I could have implemented directly in python if there wasn't a requirement it be executed from a script with sed. Can any regex guru out there help?</p>
  
  <p>EDIT:</p>
  
  <p>For the extra information about examples, this produces no matches on my system, sed 4.2.1 from the GnuWin32.sourceforge.net collection: <code>sed -r 's/method=""([^"]*)"".*path=""([^"]*)"".*accept=""([^"]*)""/"\1","\2","\3"/' logfile</code></p>
  
  <p>This produces matches for some entries: <code>sed -r 's/^.*\method\=""([A-Z]*).*path=""([a-zA-Z0-9:\/]*).*accept=""(.*)"".*/"\1","\2","\3"/ logfile</code></p>
