I'm not exactly sure what you're doing: there's no 'select' attribute on xsl:template, for example (you probably mean xsl:apply-templates?). One good method for testing in a case-insensitive way is to translate both the things you're testing into lowercase (or uppercase) and testing for equality or whatever with the translated strings. Define variables for uppercase and lowercase letters: <xsl:variable name="lowercase" select="'abcdefghijklmnopqrstuvwxyz'" /> <xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" /> Then use the translate() function to translate the two things you're comparing into lowercase and compare them: translate($word1, $uppercase, $lowercase) = translate($word2, $uppercase, $lowercase) You can put this test within a predicate in an XPath, of course. I hope that approximates to what you were after, Jeni Dr Jeni Tennison Epistemics Ltd * Strelley Hall * Nottingham * NG8 6PE tel: 0115 906 1301 * fax: 0115 906 1304 * email: jeni.tennison@xxxxxxxxxxxxxxxx XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
