I would first tokenize, then use xsl:for-each-group to remove duplicates:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<xsl:variable name="affiliations" as="element()*">
<xsl:for-each select="for $a in
Article/AuthorList/Author/Affiliation return tokenize($a,
'\[\d+\]')[normalize-space(.)]">
<affil>
<xsl:value-of select="normalize-space(.)"/>
</affil>
</xsl:for-each>
</xsl:variable>
<affiliationList>
<xsl:for-each-group select="$affiliations" group-by=".">
<xsl:copy-of select="current-group()[1]"/>
</xsl:for-each-group>
</affiliationList>
</xsl:template>
</xsl:stylesheet>
