This works fine with me. I ran the JavaScript extension specified at, http://xml.apache.org/xalan-j/extensions.html#ex-basic which works fine with me.
I downloaded the following additional components, bsf.jar from http://jakarta.apache.org/bsf/index.html js.jar from http://www.mozilla.org/rhino/ and placed these in the system CLASSPATH. please note that, the sample on Xalan site specifies: <xsl:template match="deadline"> & @numdays which means, the sample stylesheet is expecting an XML file. something like: <deadline numdays="5" ... I modified the sample to something like, <xsl:template match="/"> <p><my-ext:timelapse multiplier="2"/>We have logged your enquiry and will respond by <xsl:value-of select="my-ext:getdate('5')"/>.</p> </xsl:template> and it produces output: <?xml version="1.0" encoding="UTF-8"?><p>We have logged your enquiry and will respond by March 23, 2009 12:51:11 PM IST.</p> On Thu, Mar 12, 2009 at 11:59 PM, Bohdan <boh...@clarusmt.com> wrote: > > Hi, > > I used to work quite extensively with XSLTs about 5 years ago, using MSXML2 > and 3 at the time.
