R: [jdom-interest] XML and XSL, fine using xt command line parser, but java.util.EmptyStackException in JDom

[daniele rizzi]

shouldn't you put a </xsl:stylesheet> at the end of .xsl file?

Oggetto: [jdom-interest] XML and XSL, fine using xt command line parser,
but java.util.EmptyStackException in JDom


Sorry for the length, but I wanted to make sure there was enough information
to determine what the error is.  When I transform the xml with the xsl from
the command line, it works fine.  When using JDom (code snippet at bottom) I
get an exception.  I'm new to XSL (started yesterday :) ) so it may be a
simple error.  Thanks for your help.

Here is the error I get when attempting to transform an xml string using a
simple stylesheet:
