Hi,
I'm trying to run an xsl script from within Virtuoso that I've successfully
run externally within a php class.
When run within Virtuoso I get the following error.
SQLState: 22007
Message: XM003: XML parser detected an error:
ERROR : 37000 XM028: XPath interpreter, line 1: Namespace prefix has
been used already for other namespace URI
in the following expression:
/ in / in attribute match of tag
http://www.w3.org/1999/XSL/Transform:template in line 38 of file
virt://WS.WS.SYS_DAV_RES.RES_FULL_PATH.RES_CONTENT:/DAV/VAD/rdf_mappers/xslt/main/xml2rdf25.xsl
at line 38 column 33 of
'virt://WS.WS.SYS_DAV_RES.RES_FULL_PATH.RES_CONTENT:/DAV/VAD/rdf_mappers/xslt/main/xml2rdf25.xsl'
<xsl:template match="/">
-------------------------------^
The query I run to cause this error is -
select xslt (registry_get ('_rdf_mappers_path_') ||
'xslt/main/xml2rdf25.xsl', xtree_doc(file_to_string
('/usr/local/virtuoso-opensource/var/lib/virtuoso/db/dummy.xml')));
The xsl file and dummy xml file are attached. Would someone be able to
explain why Virtuoso doesn't like it?
Cheers
Mark
