Using xslt in pl/sql

Question

Hi!
I have a simple question: how can I use xslt in pl/sql?
I've tried this:
DECLARE
  v_XML  XMLTYPE;
  v_XSLT XMLTYPE;
BEGIN
  SELECT XMLCol --it's a valid XML.
    INTO v_XML
    FROM tb_Controle;
  SELECT XSLTCol --I don't know how to use XSLT.
    INTO v_XSLT
    FROM tb_XSLT;
  DBMS_OUTPUT.PUT_LINE(XMLTYPE.TRANSFORM(v_XML,v_XSLT).GETSTRINGVAL());
END;But it returns the error:
ERROR at line 1:
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
ORA-06512: at "SYS.XMLTYPE", line 174
ORA-06512: at line 13When a xlst has import and include tags, how the files are found? Is there something like the xsd schema registration?
  <xsl:import href="cte.xslt" />
  <xsl:include href="../functions.xslt"/> Another question: after applying the style sheet, the result is a text? 'cause I need to send the result as a text.
Thanks!
