Re: [xsl] Breaking a string into repeated elements

[Bryan Schnabel <bryan dot schnabel at bschnabel dot com>]

This kind of problem is pretty easy to find in the
archives.  Once you get past the variety of possible
delimiters, it's pretty straight-forward.

This is one way:

<xsl:template match="ListOfItems">
 <xsl:variable name="SpaceOrCommaOrBoth"
select="normalize-space(translate(text(),',',' '))"/>
 <ListofItems>
  <xsl:call-template name="Chop">
   <xsl:with-param name="SpaceOrCommaOrBoth"
select="$SpaceOrCommaOrBoth"/>
  </xsl:call-template>
 </ListofItems>
</xsl:template>

<xsl:template name="Chop">
 <xsl:param name="SpaceOrCommaOrBoth"/>
 <xsl:choose>
  <xsl:when test="contains($SpaceOrCommaOrBoth,' ')">
   <xsl:call-template name="MakeItem">
    <xsl:with-param name="ItemStff"
select="substring-before($SpaceOrCommaOrBoth,' ')"/>
   </xsl:call-template>
   <xsl:call-template name="Chop">
    <xsl:with-param name="SpaceOrCommaOrBoth"
select="substring-after($SpaceOrCommaOrBoth,' ')"/>
   </xsl:call-template>
  </xsl:when>
  <xsl:otherwise>
   <xsl:call-template name="MakeItem">
    <xsl:with-param name="ItemStff"
select="$SpaceOrCommaOrBoth"/>
   </xsl:call-template>
  </xsl:otherwise>
 </xsl:choose>
</xsl:template>

<xsl:template name="MakeItem">
 <xsl:param name="ItemStff"/>
 <item>
  <xsl:value-of select="$ItemStff"/>
 </item>
</xsl:template>
