then create an extension element where you look for an attribute where the value of the attribute is the name of the xsl variable.
Once you have the name, you can fetch its value from the expression context with this code from an extension element
XObject value = (XObject) context.getTransformer().getXPathContext().getVarStack().getVariableOrParam()
I think, haven't actually used it.
or from an extension function, as I do in the SQL code, org.apache.xalan.lib.sql.SQLQueryProcessor.java
XObject value = (XObject)ctx.getVariableOrParam(new QName(parm.getName()));

Joe, Are you trying to write an extension element or an extension function.
I figured out the function, not the element.
Extension Elements:
If you look at the source code for the Redirect extension, it is short and to the point
piece of code to see how extensions work. With Extension Functions, I don't think you
can pass in objects although that may be incorrect.
You can, though it is a bit non-intuitive.
You do: <xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' xmlns:java="http://xml.apache.org/xslt/java"; exclude-result-prefixes="java" version="1.0">
... then
<xsl:param name="myparam" />
... then <xsl:value-of select="java:methodname($myparam, $othervar)" />
Go to http://xml.apache.org/xalan-j/extensions.html#java-namespace and scroll down to the example.
<xsl:value-of select="java:format($formatter, $date)"/> does the same thing, where format is the method name and $formatter is the stf that format() is called on.
But what I really want to figure out is how do have the extention element operate on a passed in java object.
