i want to use an external ruby function "w3ready " within an xsl ssheet
in order to transform a given text to unaccentuated.

calling the function :

  <xsl:template match="/xCard">
[...]
            <xsl:for-each select="GRPS/GRP/*">
              <xsl:variable name="group_label" select="text()"/>
              <xsl:variable name="page_name"
select="ex:w3ready($group_label)"/>
[...]

part of the xml :

<xCard>
  <GRPS>
    <GRP>AB2Web</GRP>
    <GRP>Amis</GRP>
[...]
    <GRP>Sant/GRP>
    <GRP>Tourisme</GRP>
    <GRP>Vignerons</GRP>
  </GRPS>
  <vCard>
    <VERSION>2.0</VERSION>
    <ID>@uid</ID>
    <PHOTO>company.png</PHOTO>
    <GRP>Nociant</GRP>
[...]

the ruby function :

def w3ready( label )
  puts "label = #{label}, label.class = #{label.class}"
  s = ""
  case( label.class.to_s )
  when "Array"
    s = label[ 0 ].u.www_ready
  when "String"
    s = label.u.www_ready
  end
  return s
end

i'm surprised here to get an Array instead of a String ( the reason for
the case when...)

#u.www_ready transforms "Maison de la Sant into "maison_de_la_sante"
in order to build a file name.

the Array i get is of only one element...

where is my mistake here ?
