title: parsing large xml 500M with node.js
body: <p>I am using <a href="https://github.com/isaacs/sax-js" rel="nofollow">isaacs' SAX</a> to parse a huge xml file. Also <a href="http://blog.lagentz.com/nodejs/nodejs-parsing-and-transforming-large-xml-documents/" rel="nofollow">recommended by La Gentz</a>.</p>
  
  <p>The process uses about 650M of memory, how can I reduce this or allow node to use even more.</p>
  
  <pre><code>FATAL ERROR: CALL_AND_RETRY_0 Allocation failed - process out of memory
  </code></pre>
  
  <p>My XML file is larger than 300M it could grow to 1GB.</p>
