RE: Parsing a character string

Following up on my own post yesterday, here is the two-character solution

given XML:
<?xml version="1.0"?>
<days>
<deliverOnDays>NYNYYYN</deliverOnDays>
</days>

XSL:
--------------------------------------------------------------------------

<?xml version="1.0"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"> 

<xsl:variable name="weekDays" select="'S M T W ThF Sa'" />

<xsl:template name="parseYNFlags">
 <xsl:param name="YNFlags"/>
 <xsl:param name="dayAbbreviations" />
 <xsl:choose>
   <xsl:when test="substring($YNFlags, 1, 1) = 'Y'" >
     <xsl:value-of select="substring($dayAbbreviations, 1, 2)" />
   </xsl:when>
  <xsl:otherwise>_</xsl:otherwise>
 </xsl:choose>  

 <xsl:if test="string-length($YNFlags) &gt; 1" >
  <xsl:call-template name="parseYNFlags">
    <xsl:with-param name="YNFlags" select="substring($YNFlags, 2)" />
    <xsl:with-param name="dayAbbreviations"
select="substring($dayAbbreviations, 3)" />
  </xsl:call-template>
  </xsl:if>
</xsl:template>


<xsl:template match="deliverOnDays">
  <xsl:variable name="temp" >
  <xsl:call-template name="parseYNFlags" >
    <xsl:with-param name="YNFlags" select="." />
    <xsl:with-param name="dayAbbreviations" select="$weekDays" />
  </xsl:call-template>
  </xsl:variable>

  <!-- now get rid of extra spaces from result -->
  <xsl:variable name="translatedTemp" select="translate($temp, ' ', '')" />
  <xsl:value-of select="$translatedTemp" /> 
</xsl:template>
</xsl:stylesheet>
