XMLTRANSORM - LPX-00607: Invalid reference - xsl:variable

Question

Hi,
I'm working on Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit.
I have a problem using XMLTRANSFORM method with variable (ie. SenderDN).
There is a table "ma_table" with three columns : "id", "data_xml" and "data_xsl".
Here is the query used :
SELECT XMLTRANSFORM (data_xml, data_xsl) FROM ma_table WHERE id = 64;Here is the data to transform :
<?xml version="1.0" encoding="ISO-8859-1"?>
<SOSTA xmlns="http://www.xxxxxx.com/yyyy/pipo">
     <infos>
          <generated>2009-08-19T16:23:56</generated>

</SOSTA>And here is the stylesheet :

</xsl:stylesheet>And I get this error message :
ORA-31011: XML parsing failed
ORA-19202: Erroroccured in XML processing
LPX-00607: Invalid reference: 'SenderDN'Why this error?
How to use this variable?
Thanks,

Answer 1

Hi,
I'va found the solution by modifying the <xsl:stylesheet> like this :
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
     xmlns:yyyy="http://www.xxxxxx.com/yyyy/pipo"
     xmlns="urn:swift:saa:xsd:saa.2.0">(adding xmlns="urn:swift:saa:xsd:saa.2.0")
But I don't understand why it work fine now ???
If anyone have an explanation?
Thanks,
-Dominique
