Problems wth XSLPROCESSOR

Question

Greetings,
I am trying to develop a PLSQL function that, given the URL of a XML file, it returns a HTML file through a prepared XLS file
So far, the test procedure to check if the function is working ends with a ORA-20103: Null input is not allowed error.
Function is as follows:
     FUNCTION translate_XML(path_xml VARCHAR2, path_xsl VARCHAR2) RETURN CLOB IS
          v_return               CLOB;
          v_processor          SYS.XSLPROCESSOR.PROCESSOR;
          v_style               SYS.XSLPROCESSOR.STYLESHEET;
          v_xmldom               SYS.XMLDOM.DOMDOCUMENT;
          BEGIN
          v_xmldom := SYS.XMLPARSER.PARSE(path_xml);
          v_style := SYS.XSLPROCESSOR.NEWSTYLESHEET(path_xsl, NULL);
          v_processor := SYS.XSLPROCESSOR.NEWPROCESSOR;
          SYS.XSLPROCESSOR.PROCESSXSL(v_processor, v_style, v_xmldom, v_return);
          RETURN v_return;
          EXCEPTION
when others then
sys.xslprocessor.freeprocessor(v_processor);
raise;
          END;
could anyone point me in the right direction, please?

First, try resetting the iPod.

If that does not work, you should probably use the Restore button in iTunes to erase the iPod and initialize its software. Then sync everything back, videos and music.
FYI - It's a 5th Gen iPod.
