Do a string replace like the one in the new xml view of the list:

echo trim( str_replace( array( '<!-- Begin: SEBLOD 3.x Document { www.seblod.com } -->', '<!-- End: SEBLOD 3.x (App Builder & CCK for Joomla!) { www.seblod.com } -->' ), '', $this->data ) );

Thanks for the Answer :-) 

Where can i find the xml view? I use seb_minima with own positions.

Thanks

In components\com_cck\views\list\tmpl\xml.php

OK 

Thank you.

It's already in there but it don't works for me :-(

Maybe J2.5 is the problem.

i'll try it on joomla3 

thanks

i found a "solution" :-S

change the core file libaries/cck/rendering/document/html/html.php Line 202

// $data = '<!-- Begin: SEBLOD 3.x Document { www.seblod.com } -->'. $data .'<!-- End: SEBLOD 3.x (App Builder & CCK for Joomla!) { www.seblod.com } -->';

i know: "Don't change core files!!"

But so far it works ;-)
