Populate an array -- extension functions in LotusXSL

["Garriss Jr.,James P." <jgarriss@xxxxxxxxx>]

I am trying to read in several values from an XML file and store them in an 
array using an extension function written in Javascript.  Despite what 
appears to be rather simple code, I am getting an XPath error -- "XSL 
process was not successful".  I'm using LotusXSL 0.18.1 with XML4J 2.0.15 
and JDK 1.1.7B on an NT 4.0 server.  I would appreciate any thoughts on why 
this isn't working or even better ideas for how to store values in an array.

[BTW, I realize using an xsl:variable element is a rather unorthodox method 
for calling a function, but I couldn't think of a better way of calling one 
that doesn't have a returned value.  Ideas welcome.]

TIA,
