If you're using a 1.0 stylesheet the common method of case conversion is translate() : <xsl:variable name="lowercase" select="'abcdefghijklmnopqrstuvwxyz'" /> <xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" /> <xsl:template match="/"> <xsl:value-of select="translate(doc, $lowercase, $uppercase)" /> </xsl:template> Anton Gogolev XSLT 2.0 has upper-case() and lower
