RE: [xsl] CSV to XML

[chun ji <cji_work@xxxxxxxxx>]

Hi Michael, 
Thanks for the tips. It works after I removed this
piece code in the one you gave:  

as="xs:string()*"

Because otherwise, I see an error during the runtime: 
"
 XPST0003: SequenceType syntax error at char 0 in
{xs:string()}:
    Expected type name in SequenceType, found
<function>(
Failed to compile stylesheet. 1 error detected.
" 
Do I need to do some package update? 
* I am using "Saxon 8.9J from Saxonica", "jdk 1.6" on
a linux box. 
* And runtime command is : java -cp
/home/cji/XML/saxonsa8-9j/saxon8sa.jar
net.sf.saxon.Transform ... 


Anyway, here is the my latest xsl file.

Thanks all for the tips.
