Don't use xsl:text to write xml. Don't think in terms of generating
start and end tags. You can't separate the two. Forget about the ul s
for a bit, pull out your conditions, and make certain your creation of
li s looks something like:

<li><xsl:value-of select="@name"/></li>

and nothing like:

<xsl:text
disable-output-escaping="yes">&lt;li&gt;</xsl:text>             
<xsl:value-of select="@name"/>
<xsl:text
disable-output-escaping="yes">&lt;/li&gt;</xsl:text>
 
Then you can start asking: How do I get some ul s in there? (Hint: no
xsl:text allowed. Really.)

Though someone else will have to answer because I'll be offline.
