[1.8] XML Database League Plugin

[DiegoPino]

I am still studying but I think... at this point to continue with the Plugin Development need help...

The Stylesheet Language .xsl  in the file .xml does not work for Display Style MyBB?  Why? 

Example Online:

- xmleague.xml
- xml-database-league.php  (Plugin Read The File xmleague.xml but not Display the Stylesheet .xsl) in MyBB.
- XSLTLeague.xsl  Stylesheet for the File xmleague.xml

<?xml-stylesheet type="text/xsl" href="XSLTLeague.xsl" ?>

Any suggestion or recommendation is welcome!

Thanks in Advance for the Support!
