Add repeating XML code n times via xslt template

I want to repeat the following lines in an XML document n times, n being set in the variable $n

<Cell ss:StyleID="s22">
    <Data ss:Type="String">WSCEAllergens[i]</Data>
</Cell>

and rather than writing clumsy cascades like

<Cell ss:StyleID="s22">
  <Data ss:Type="String">WSCEAllergens[0]</Data>
</Cell>
<xsl:if test="$n &gt; 1>
  <Cell ss:StyleID="s22">
    <Data ss:Type="String">WSCEAllergens[1]</Data>
  </Cell>
    <xsl:if test="$n &gt; 2>
      <Cell ss:StyleID="s22">
        <Data ss:Type="String">WSCEAllergens[2]</Data>
      </Cell>
    .
    .
    .
    </xsl:if>
  </xsl:if>

I'd like to solve this with an elegant template, but I have no idea how to iteratively glue XML and text strings together to get something like this:

n=3

<Cell ss:StyleID="s22">
    <Data ss:Type="String">WSCEAllergens[0]</Data>
</Cell>
<Cell ss:StyleID="s22">
    <Data ss:Type="String">WSCEAllergens[1]</Data>
</Cell>
<Cell ss:StyleID="s22">
    <Data ss:Type="String">WSCEAllergens[2]</Data>
</Cell>
