Hi,
I want to convert the decimal integers returned by the XPath 2 function fn:string-to-codepoints into a sequence of strings that use the conventional "U+..." hexadecimal notation of the Unicode standard. Neither the XPath 2 spec nor the XSLT FAQ offered a complete solution to this problem, so I developed my own. It is working, but I wonder how to integrate these two functions, which convert a decimal integer into its hexadecimal equivalent, into a single function which still returns just one string: <xsl:function name="my:decimal-to-hex" as="xs:string"> <xsl:param name="decimalNumber"/> <xsl:sequence select="string-join(my:decimal-to-hex-internal($decimalNumber),'')"/> </xsl:function> <xsl:function name="my:decimal-to-hex-internal" as="xs:string+">
<xsl:param name="decimalNumber"/>
<xsl:variable name="hexDigits" select="'0123456789ABCDEF'"/>
<xsl:if test="$decimalNumber >= 16">
<xsl:sequence
select="my:decimal-to-hex-internal(floor($decimalNumber div 16))"/>
</xsl:if>
<xsl:sequence
select="substring($hexDigits, ($decimalNumber mod 16) + 1, 1)"/>
</xsl:function>Yves
