Ticket #2665: xanga_LATEST.php

<?php

//Xanga archive importer by Jeremy Jay
//Borrows heavily from the LiveJournal import script.
//
//Modified for current WP (2.1+) release and for current Xanga archive style by Daniel Kozlowski
//
//ATTN:  unhtmlentities() has been disabled due to it's turning all ". " into ".? " 
//       once the post was imported into wordpress 2.1.  Thus, it has been disabled.  If 
//       you're using a version of PHP earlier than 4.3, you'll need to un-comment
//       calls to unhtmlentities() in this script.  They are on lines 82 and 120.
//
//ATTN:  I've run into some Xanga archives where the timestamp for a post or comment is 
//          missing a zero.  For example, "12:08" is printed as "12:8".  This script 
//          cannot read those!  Please read through your code if some of the times are
//       coming up weird once you've imported the archive files.

Pick an archive file to upload and click Import.').'</p>';
