title: Writing to File in Server-Side Javascript
body: <p>I'm studying Web Applications at university, and at the moment we have an assignment: build a 'blog' using only CSS, Javascript and XML. We have to store the blog posts in a .xml file, which is what's got me stuck at the moment.</p>
  
  <p>So, essentially I need to be able to write a Javascript function which writes to a server-side file. There are so many better ways to do this but we literally <em>have</em> to do it in Javascript. The teacher is totally unhelpful and everyone I asked thinks it can't be done.</p>
  
  <p>I don't want anyone doing my work for me or anything, just it'd be nice to know how to do this, if it's even possible.</p>
  
  <p>Cheers in advance.</p>
