Uppercase in XSLT

XPATH doesn't have a built in ToUpper() or ToLower() function.  However, you can use the translate function to switch cases.  Here's an example that changes the word "Upper" to all upper case.

<xsl:variable name="text" select="'Upper'" />
<xsl:value-of select="translate($text, 'abcdefghijklmnopqrstuvwxyz', 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />

If you want to go the other way and lowercase your string, just flip-flop the alphabet strings.

<xsl:variable name="text" select="'Upper'" />
<xsl:value-of select="translate($text, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'" />
