Re: recursion questions

To save somebody the time trying to explain the basics to me... I figured it
out. It was much simpler than I thought.  Anyway, here is the template I
came up with that produces (most of) the desired results:

<xsl:template match="section">
   <xsl:variable name="folder" select="@folder"/>

   <xsl:value-of select="$folder"/> = new List(true, width, height,
"#EEEEEE");
   <xsl:value-of select="$folder"/>.onexpand = colorize;
   <xsl:value-of select="$folder"/>.setFont(<![CDATA["<FONT
FACE='Arial,Helvetica' SIZE='-1'>","</FONT>"]]>);

   <xsl:apply-templates select="section"/>
   <xsl:variable name="parent.folder" select="parent::section/@folder"/>
   <xsl:if test="$parent.folder!=''">
      <xsl:value-of select="$parent.folder"/>.addList(<xsl:value-of
select="$folder"/>, "<xsl:value-of select="@label"/>");
   </xsl:if>
</xsl:template>
