[xsl] Converting a string to Uppercase or Lowercase without using translate() ?

["Gareth Howells" <subscriptions@xxxxxxxxxxxxxxxxxxxxxxx>]

Hello everyone,

I'm trying to convert a string to uppercase before using it in a select
statement using XSLT 1.0, and for now I'm using translate() as follows:

<xsl:variable name="pClubCaps" select="translate($pClub,
'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSSTUVWXYZ')" />

where $pClub is a parameter passed to the stylesheet from a JSP page. Of
course, converting to lowercase would simply require the second and third
parameters of translate() to be switched.

I was wondering if there's a nicer way of converting strings to upper or
lower case, rather than using translate()?

Thanks
Gareth
