I'm trying to learn high order functions, and I have some difficulties. If someone could help...


I have a normal function :

 B  <xsl:function name="nu:camelCase" as="xs:string?">
 B B B  <xsl:param name="s" as="xs:string?"/>
 B B B  ...
 B  </xsl:function>

I want to apply it on each word of a sentence :

B <xsl:function name="nu:clearUsername" as="xs:string?">
B B B <xsl:param name="name" as="xs:string?"/>
B B B <xsl:choose>
B B B B B <xsl:when test="empty($name)"><xsl:sequence select="()"/></xsl:when>
B B B B B <xsl:when test="contains($name, ' ')">
B B B B B B B <xsl:variable name="temp" select="tokenize($name, ' ')"/>
B B B B B B B <xsl:sequence select="string-join(for-each($temp, nu:camelCase#1), ' ')"/>
B B B B B </xsl:when>
B B B B B <xsl:otherwise>
B B B B B B B <xsl:sequence select="$name"/>
B B B B B </xsl:otherwise>
B B B </xsl:choose>
B </xsl:function>

Does the for-each is correct ?

Is there another syntax to make this work with Saxon-HE ?

so you can use
  for $i in $temp return nu:camelCase($i)

Is there a better way to do this ?
