 If there isn't, can you please keep the non simple solution (ie the one where you have to create a template to compare two strings) to yourself as I would like to have a stab at it myself.OK, I did the non-simple solution, so feel free to add your own now. <xsl:template name="strcmp"> <xsl:param name="string_1"/> <xsl:param name="string_2"/> <xsl:variable name="alphabet">0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ</xsl:variable> <xsl:variable name="string_1_first_letter_pos"> <xsl:call-template name="alphabet_pos"> <xsl:with-param name="letter" select="substring($string_1, 1, 1)"/> <xsl:with-param name="alphabet" select="$alphabet"/> <xsl:with-param name="alphabet_tot" select="string-length($alphabet)"/> <xsl:with-param name="pos" select="1"/> </xsl:call-template> </xsl:variable> <xsl:variable name="string_2_first_letter_pos"> <xsl:call-template name="alphabet_pos"> <xsl:with-param name="letter" select="substring($string_2, 1, 1)"/> <xsl:with-param name="alphabet" select="$alphabet"/> <xsl:with-param name="alphabet_tot" select="string-length($alphabet)"/> <xsl:with-param name="pos" select="1"/> </xsl:call-template> </xsl:variable> <xsl:choose> <xsl:when test="$string_1 = $string_2"> <xsl:text>0</xsl:text> </xsl:when> <xsl:when test="$string_1_first_letter_pos > $string_2_first_letter_pos"> <xsl:text>-1</xsl:text> </xsl:when> <xsl:when test="$string_1_first_letter_pos < $string_2_first_letter_pos"> <xsl:text>1</xsl:text> </xsl:when> <xsl:when test="string-length(substring($string_1, 2)) = 0"> <xsl:text>-1</xsl:text> </xsl:when> <xsl:when test="string-length(substring($string_2, 2)) = 0"> <xsl:text>1</xsl:text> </xsl:when> <xsl:otherwise> <xsl:call-template name="strcmp"> <xsl:with-param name="string_1" select="substring($string_1, 2)"/> <xsl:with-param name="string_2" select="substring($string_2, 2)"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:template> <!-- Capitalises a string --> <xsl:template name="capitalise"> <xsl:param name="string"/> <xsl:variable name="lowercase_alphabet"> <xsl:text>abcdefghijklmnopqrstuvwxyz</xsl:text> </xsl:variable> <xsl:variable name="uppercase_alphabet"> <xsl:text>ABCDEFGHIJKLMNOPQRSTUVWXYZ</xsl:text> </xsl:variable> <xsl:value-of select="translate($string, $lowercase_alphabet, $uppercase_alphabet)"/> </xsl:template> <!-- Find the position in a given alphabet of a letter --> <xsl:template name="alphabet_pos"> <xsl:param name="letter"/> <xsl:param name="alphabet"/> <xsl:param name="alphabet_tot"/> <xsl:param name="pos"/> <xsl:if test="not(contains($alphabet, $letter))"> <xsl:value-of select="-1"/> </xsl:if> <xsl:if test="substring($alphabet, 1, 1) = $letter or $pos = $alphabet_tot"> <xsl:value-of select="$pos"/> </xsl:if> <xsl:if test="contains(substring($alphabet, 2), $letter)"> <xsl:call-template name="alphabet_pos"> <xsl:with-param name="letter" select="$letter"/> <xsl:with-param name="alphabet" select="substring($alphabet, 2)"/> <xsl:with-param name="alphabet_tot" select="$alphabet_tot"/> <xsl:with-param name="pos" select="$pos + 1"/> </xsl:call-template> </xsl:if> </xsl:template> If anyone has some hints about how I can do this better, please tell me.
