[xsl] problems with recurssion

["rafael vazquez" <rc_vazquez@xxxxxxxxxxx>]

Hi All! I want to build a HTML document from an XML document. The XML 
document contains information about a shopping list. I want to build a text 
box  for each article existing in the shopping list. Because I don´t know 
the number of articles in the shopping list, the name of the box for each 
article would be nameOfTextBox-0 for the first article, nameOfTextBox-1 for 
the second, and so on...
To generate the corresponding indexes of the text boxes I have to use 
recurssion, due to the lacking of an assignment operator for the variables.
The problem is that the following code only creates the text boxes for the 
first element of the list. The code is the following:

...
<xsl:template match="/LISTA">
<xsl:element name="INPUT">
 <xsl:attribute name="TYPE">TEXT</xsl:attribute>
 <xsl:attribute name="NAME">nombreLista</xsl:attribute>
  <xsl:attribute name="VALUE"><xsl:value-of select="./ID/NOMBRE_LISTA"/>
 </xsl:attribute>
</xsl:element>
<xsl:element name="INPUT">
 <xsl:attribute name="TYPE">TEXT</xsl:attribute>
 <xsl:attribute name="NAME">fechaCreacion</xsl:attribute>
  <xsl:attribute name="VALUE"><xsl:value-of select="./ID/FECHA_CREACION"/>
 </xsl:attribute>
</xsl:element>
<xsl:call-template name="articulos">
 <xsl:with-param name="numArr" select="0"/>
 <xsl:with-param name="listaNodos" select="."/>
</xsl:call-template>
<INPUT TYPE="button" onClick="alert(hidArtDC0.value)"/>
</xsl:template>


<xsl:template name="articulos">
 <xsl:param name="numArr"/>
 <xsl:param name="listaNodos"/>
 <xsl:variable name="nodoAct" select="$listaNodos[1]"/>
 <xsl:variable name="restoNodos" select="$listaNodos[position()!=1]"/>
 <xsl:call-template name="crearArticulos">
   <xsl:with-param name="numArr" select="$numArr"/>
   <xsl:with-param name="nodoAct" select="$nodoAct"/>
 </xsl:call-template>
 <xsl:if test="listaNodos">
   <xsl:call-template name="articulos">
     <xsl:with-param name="numArr" select="number($numArr)+1"/>
     <xsl:with-param name="restoNodos" select="$restoNodos"/>
   </xsl:call-template>
 </xsl:if>
</xsl:template>

<xsl:template name="crearArticulos">
 <xsl:param name="numArr"/>
 <xsl:param name="nodoAct"/>
 <xsl:element name="INPUT">
  <xsl:attribute name="TYPE">HIDDEN</xsl:attribute>
  <xsl:attribute name="NAME">hidArtDC<xsl:value-of 
select="$numArr"/></xsl:attribute>
</xsl:template>
...


My XML is...

<?xml version = '1.0' encoding='iso-8859-1'?>
<?xml-stylesheet href='../XSLT/FormatoListas.xsl' type='text/xsl'?>
<LISTA>
<ID>
<NOMBRE_LISTA>sabado</NOMBRE_LISTA>
<FECHA_CREACION>8/11/2001 10:17:16</FECHA_CREACION>
</ID>
<ARTICULO>
<DESCRIPCION_CORTA>desco_corta</DESCRIPCION_CORTA>
</ARTICULO>
<ARTICULO>
<DESCRIPCION_CORTA>desc2_corta</DESCRIPCION_CORTA>
</ARTICULO>
</LISTA>

Thanks in advance, friends!
