Can someone point me in the right direction to pass parameters (or registry
values) into an XSLT transform?
In the documentation for the XSLT mediator it states,
"Optionally parameters (XSLT) could be passed into the transformation
through the 'property' elements."
I am trying to take advantage of this. Here is my synapse.xml code:
<localEntry key="xslt-key-resp"
src="file:repository/conf/resources/transform/MyTransform.xslt" />
.
.
.
<xslt key="xslt-key-resp">
<property name="TestMe" value="This is a test"/>
</xslt>
and MyTransform.xslt:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fn="http://www.w3.org/2005/02/xpath-functions";>
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">

When I run it, I get an exception:

Alternatively, is there a way to use "get-property('Registry-variable')" in
the XSLT file?
Is there an example of how to do this?
Thanks,
Bill
