Little trick to handle libXML bug...
As we know that the newest libXML librabry (2.7.3) still having bug...stll striping html tag when parsing XML document that created with blog client.

The solution is downgrade your libXML or use another lib such as expat...but this is big and heavy solution for me :(
And of course you can't do this if you have limited acces to the hosting server.

Another solution is very simple, as 1,2,3 but use it for your own risk..

  • open xmlrpc.inc
  • edit on xmlrpc_message function
  • add this simple 3 line code before "$xmlrpc_message->message = $message;"
  $message =str_replace("<","<",$message );
  $message =str_replace(">",">",$message );
  $message =str_replace("&","&",$message );

You can see a complete tutorial on http://www.janganan.com/2009/02/how-to-handle-libxml-bug-in-drupal.html
And if make drupal not stable please correct me..i'm not goog in PHP code..

thx
