RE: How to delete empty element tag from output XML?

Thanks to Kay Michael and Jeni Tennison for your help. A general template is
what I am looking for. I wrote a template, it's more like a C function
except more awkward. Most of the codes is for print tag. I wish I can use
<xsl:element> to print the tag which is passed by parameter but don't know
how to assign the parameter to the name of element.

Have a nice day

here's the XSLT stylesheet.
