Hi all,

I have a variable "Keywords" with several keywords inside.
They are seperated with ;.
so i want per xslt to split this content into single keywords,
like this:

<keywordset>
  <keyword>Keyword1</keyword>
  <keyword>Keyword2</keyword>
  <keyword>Keyword3</keyword>
  <keyword>Keyword4</keyword>
  <keyword>Keyword5</keyword>
</keywordset>

xml:

<Keywords>Keyword1; Keyword2; Keyword3; Keyword4; Keyword5;
Keyword6</Keywords>


here's an xslt1.0 version without extension functions:

<xsl:template name="tokenize">
         <xsl:param name="inputString"/>
         <xsl:param name="separator" select="' '"/>
         <xsl:param name="resultElement" select="'item'"/>
         <xsl:variable
                 name="token"
                 select="substring-before($inputString, $separator)"
         />
         <xsl:variable
                 name="nextToken"
                 select="substring-after($inputString, $separator)"
         />
         <xsl:if test="$token">
                 <xsl:element name="{$resultElement}">
                         <xsl:value-of select="$token"/>
                 </xsl:element>
         </xsl:if>
         <xsl:if test="$nextToken">
                 <xsl:call-template name="tokenize">
                         <xsl:with-param
                                 name="inputString"
                                 select="$nextToken"/>
                         <xsl:with-param
                                 name="separator"
                                 select="$separator"/>
                         <xsl:with-param
                                 name="resultElement"
                                 select="$resultElement"/>
                 </xsl:call-template>
         </xsl:if>
</xsl:template>

and here's how you would use it to get what you want:


<xsl:template match="Keywords">
         <keywords>
         <xsl:call-template name="tokenize">
                 <xsl:with-param
                         name="inputString"
                         select="."/>
                 <xsl:with-param
                         name="separator"
                         select="';'"/>
                 <xsl:with-param
                         name="resultElement"
                         select="'keyword'"/>
         </xsl:call-template>
         </keywords>
</xsl:template>
