Re: Split with delimiter and remove duplicate with xs

I am trying to use the combination of <xsl:for-each-group> to avoid
duplicate and split data of <Affiliation> , using [number] as the delimiter.

    <xsl:template match="/Article">
        <xsl:variable name="affiliations" as="xs:string+">
            <xsl:for-each select="//Affiliation">
                <xsl:analyze-string select="string(.)"
                    regex="\[\d+\]([^\[]*)">
                    <xsl:matching-substring>
                        <xsl:sequence
                        select="normalize-space(regex-group(1))"/>
                    </xsl:matching-substring>
                    <xsl:non-matching-substring>
                        <xsl:if test="normalize-space(.)">
                            <xsl:sequence select="normalize-space(.)"/>
                        </xsl:if>
                    </xsl:non-matching-substring>
                </xsl:analyze-string>
            </xsl:for-each>
        </xsl:variable>

        <affiliationlist>
            <xsl:for-each select="distinct-values($affiliations)">
            <affil><xsl:value-of select="."/></affil>
        </xsl:for-each>
        </affiliationlist>
    </xsl:template>
</xsl:stylesheet>
