ShoXS: a Shorter XSL Syntax

The last two year I have been doing quite a bit of
XSL scripting, but after a while I found the
syntax to be a bit too verbose to my taste. So, to 
help do the scripting I put together a little tool 
that translates XSL to a more compact syntax, edit
in that syntax and translate back to XSL. This syntax
is ShoXS (SHOrter Xsl Syntax, you get it:-).

ShoXS is a bit Javascript-ish, as far as XSL allows 
this. Just to give an impression, an XSL fragment 
from the XSL FAQ and its ShoXS equivalent:

===============================XSL=============================== 

<xsl:template name="displayyear">
    <xsl:param name="yearlist"/>
    <xsl:variable name="year" 
        select="substring-before($yearlist,',')"/>
    <xsl:choose>
        <xsl:when test="string-length($year) > 0">
            <td><xsl:value-of select="$year"/></td>
            <xsl:call-template name="displayyear">
                <xsl:with-param 
             name="yearlist"><xsl:value-of 
             select="substring-after($yearlist,',')"/>
               </xsl:with-param>
            </xsl:call-template>
       </xsl:when>
        <xsl:otherwise>
             <td><xsl:value-of select="$yearlist"/></td>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

===============================ShoXS============================== 
 
fun displayyear {
    par yearlist=""{}
    var year="substring-before($yearlist,',')"{}
    switch {
        case(string-length($year) > 0) {
            <td>val($year)</td>
            call displayyear {
                wpar yearlist=""{val(substring-after($yearlist,','))
               }
            }
        }
        default{
             <td>val($yearlist)</td>
        }
    }
}
 
=================================================================== 

If you want to see a bit more about ShoXS, have
a browse on http://www.xm.co.nz/ShoXS.htm where you
can find ShoXSPad, a notepad like tool to toggle between 
XSL and ShoXS. A bit more useful is a version integrated
in jEdit, which I use myself. 

It should be easy to get to grips with ShoXS if you know XSL: 
just key in the XSL, toggle to ShoXS and look at the ShoXS 
equivalent.

Let me know if you have any constructive comments or 
suggestions (or find any bugs).

Enjoy,
