[xsl] XML structure to HTML unordered list

Hey all,

I'm struggling to figure out a good way to transform a XML structure into a HTML unordered list. So far the solution I've come up with looks like this:

Sample index.xml file

   <?xml version="1.0" encoding="iso-8859-1"?>
   <?xml-stylesheet type="text/xsl" href="index.xsl"?>
   <root_element>
       <item id="1">
           desc 1
           <item id="11">
               desc 11
           </item>
           <item id="12">
               desc 12
               <item id="121">
                   desc 121
                   <item id="1211">
                       desc 1211
                       <item id="12111">
                           desc 122111
                           <item id="1211111">
                               desc 1211111
                               <item id="12111111">
                                   desc 12111111
                               </item>
                               <item id="12111112">
                                 desc 12111112
                               </item>
                           </item>
                       </item>
                   </item>
               </item>
           </item>
       </item>
       <item id="2">
           desc 2
           <item id="21">
               desc 21
           </item>
           <item id="22">
               desc 22
               <item id="221">
                   desc 221
               </item>
               <item id="222">
                   desc 222
               </item>
           </item>
           <item id="23">
               desc 23
           </item>
       </item>
   </root_element>

And here's my index.xsl file

<?xml version="1.0" encoding="iso-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="html" omit-xml-declaration="yes"/>

   <xsl:template match="root_element">
       <html>
       <body>
           <xsl:call-template name="unordered-list">
               <xsl:with-param name="items" select="item"/>
           </xsl:call-template>
       </body>
       </html>
   </xsl:template>

   <xsl:template name="unordered-list">
       <xsl:param name="items" select="/.."/>
       <ul>
           <xsl:for-each select="$items">
               <li>
                   <xsl:value-of select="text()"/>
                   <xsl:if test="item">
                       <xsl:call-template name="unordered-list">
                           <xsl:with-param name="items" select="item"/>
                       </xsl:call-template>
                   </xsl:if>
               </li>
           </xsl:for-each>
       </ul>
   </xsl:template>

</xsl:stylesheet>

The above produces what I want, and it seems quite solid. But is there perhaps another (better?) way to solve this task? I'm limited to XSLT 1.0.

Sincerely,
Thomas
