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>
