Re: Sorting problem...

I'm trying to sort some concatenated strings in a dropdown box in my XSL.
(I'm also sure there's a more compact way to write my XSL, frankly).  My XML
is:

<root sub_id="84">
	<folder name="c" cdate="2/13/01" id="f_49">
		<folder name="m" cdate="2/13/01" id="f_42" />
	</folder>
	<folder name="y" cdate="2/13/01" id="f_45" />
	<folder name="d" cdate="2/13/01" id="f_43" />
	<folder name="r" cdate="2/13/01" id="f_44" />
	<folder name="d" cdate="2/13/01" id="f_49">
		<folder name="t" cdate="2/13/01" id="f_42">
			<folder name="z" cdate="2/13/01" id="f_42">
		</folder>
	</folder>
</root>

I want my output to look alphabetical like the following:

-c
--c:m
-d
--d:t
---d:t:z
-r
-y

My XSL looks like this:

<xsl:apply-templates select="folder">
<xsl:sort lang="en" select="@name" data-type="text"/>
</xsl:apply-templates>

<xsl:template match="folder">
<xsl:value-of select="@name"/>
<xsl:apply-templates/>
</xsl:template>
</xsl:stylesheet>
