RE: determine the number of payment methods and specif

How about a two-pass solution?

<xsl:template match="paymentMethods">
   <xsl:variable name="temp">
     <xsl:apply-templates select="directDebit"/>
     <xsl:apply-templates select="creditCard"/>
     <xsl:apply-templates select="invoice"/>
   </xsl:variable>
   <xsl:apply-templates select="$temp/*" mode="add-class"
</xsl:template>

<xsl:template match="directDebit">
  <directDebit>Payment by <br/>Direct Debit</directDebit>
</xsl:template>

<xsl:template match="creditCard">
  <creditCard>Payment by <br/>Credit Card</creditCard>
</xsl:template>

<xsl:template match="invoice">
  <invoice>Payment by <br/>Invoice</invoice>
</xsl:template>

<xsl:template match="*" mode="add-class">
  <xsl:variable name="status">
    <xsl:choose>
      <xsl:when test="$label = local-name()">current</xsl:when>
      <xsl:when test="preceding-sibling::*[local-name() =
$label]">completed</xsl:when>
      <xsl:otherwise/>
    </xsl:choose>
  </xsl:variable>
  <li class="doubleLine {$status}"><xsl:copy-of select="node()"/></li>
</xsl:template>

Probably doesn't save many lines of code, and it runs into the 1.0
node-set() restriction, but it strikes me as capturing the logic of the
problem a bit better: if a fourth and fifth kind of payment were added,
fewer changes would be needed, as the final template has no knowledge of the
different kinds of payment.

Cheers,
