If we use regular expression like

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
B  version="3.0"
B  xmlns:xs="http://www.w3.org/2001/XMLSchema";
B  exclude-result-prefixes="#all">

B  <xsl:param name="input" as="xs:string">THEN THE CURTAIN FELL</xsl:param>

B  <xsl:output method="text" item-separator="&#10;"/>

B  <xsl:template match="/" name="xsl:initial-template">
B B B  <xsl:iterate select="(1 to count(analyze-string($input,
'[AEIOU]')/*:match))">
B B B B B  <xsl:param name="string" as="xs:string" select="$input"/>
B B B B B  <xsl:sequence select="$string"/>
B B B B B  <xsl:variable name="match"
select="replace($string,'(^.*?[AEIOU]).*$','$1')"/>
B B B B B  <xsl:next-iteration>
B B B B B B B  <xsl:with-param name="string"
select="substring-after($string,
$match)"/>
B B B B B  </xsl:next-iteration>
B B B  </xsl:iterate>
B  </xsl:template>

</xsl:stylesheet>

we get the result

THEN THE CURTAIN FELL
N THE CURTAIN FELL
B CURTAIN FELL
RTAIN FELL
IN FELL
N FELL
