In the XSLT template I will expand an input variable like this:
<xsl:value-of select="$ClubName" />
But if that $ClubName starts with a vowel, I need to prefix with l'
I think there may be a regular expression technique to do this.
In xslt 1.0 you could try this:
<xsl:if test="contains('AEIOUaeiou',substring($ClubName,1,1))">
<xsl:text>l'</xsl:text>
</xsl:if>
<xsl:value-of select="$ClubName"/>
