<p>Howdy! This importer allows you to extract posts from a LiveJournal XML export file. To get started you must edit the following line in this file (<code>import-livejournal.php</code>) </p>
<p><code>define('XMLFILE', '');</code></p>
<p>You want to define where the XML file we'll be working with is, for example: </p>
<p><code>define('XMLFILE', '2002-04.xml');</code></p>
<p>You have to do this manually for security reasons.</p>
<p>If you've done that and you&#8217;re all ready, <a href="import-livejournal.php?step=1">let's go</a>!</p>
