You say XPath 2.0, so I'm not sure if you really mean only available in XPath. If you are really doing this in XSLT 2.0 you can always write your own function, which you can then use within the XPath selections: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:f="uri:local-functions"> <xsl:output method="text"/> <xsl:template name="example"> <xsl:for-each select="f:split('howdy!')"> <xsl:value-of select="concat('"',.,'"',' ')"/> </xsl:for-each> </xsl:template> <xsl:function name="f:split"> <xsl:param name="str" as="xs:string"/> <xsl:analyze-string select="$str" regex="."> <xsl:matching-substring> <xsl:sequence select="."/> </xsl:matching-substring> </xsl:analyze-string> </xsl:function> </xsl:stylesheet> When run, returns: $ saxon -it example split.xsl "h" "o" "w" "d" "y" "!"
