xslt 2.0 - Splitfunction gives troubles -

i'm facing following problem or challenge. i've element in source xml can have 450 characters. xslt want transform chunks of 75 characters.

...     <t61>      <parentinfo>someinfo</parentinfo>      <t86>         <info>abcdefghijklmnopqrstuvwxyz01234567890abcdefghijklmnopqrstuvwxyz01234567890</info>      </t86>     </t61> ... 

the output generate should like:

<t31>         <x>abcdefghijklmnopqrstuvwxyz01234567890</x> </t31> <t31>     <x>abcdefghijklmnopqrstuvwxyz01234567890</x> </t31> 

in code use template t61 work. thought create template t86 , call inside t61 template seems not work because i've complete string. created function split string in parts of 75. outcome of function still complete string.

i used function earlier post:

        <xsl:function name="my:splititup" as="xs:string">         <xsl:param name="input" as="xs:string"/>         <xsl:param name="chunk-size" as="xs:integer"/>         <xsl:value-of>             <xsl:for-each-group select="string-to-codepoints($input)" group-by="(position() -1) idiv $chunk-size">                 <xsl:sequence select="codepoints-to-string(current-group())"/>             </xsl:for-each-group>         </xsl:value-of>     </xsl:function> ...     <xsl:template match="t86">      <xsl:for-each select="my:splititup(info, 75)">         <t31>             <communication>             <xsl:value-of select="." />             </communication>         </t31>         </xsl:for-each>     </xsl:template> 

this structure result in complete string. in debug see split concatenates result together. can somehow come out of function?

best regards dirk

please have xslt need set <xsl:param name="stringrequired" select="xs:integer(13)"/> chunk text:

    <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"   xmlns:xs="http://www.w3.org/2001/xmlschema">   <xsl:output method="xml" omit-xml-declaration="yes" indent="yes" encoding="utf-8"/>    <xsl:param name="xml">     <info>abcdefghijklmnopqrstuvwxyz01234567890abcdefghijklmnopqrstuvwxyz01234567890</info>   </xsl:param>   <xsl:param name="stringrequired" select="xs:integer(13)"/>   <xsl:param name="xmllenfgh" select="string-length($xml)"/>   <xsl:template match="/">     <xsl:choose>       <xsl:when test="$xmllenfgh gt $stringrequired">         <xsl:call-template name="getpart"/>       </xsl:when>       <xsl:otherwise>         <t31>           <x>             <xsl:value-of select="$xml/info"/>           </x>         </t31>       </xsl:otherwise>     </xsl:choose>   </xsl:template>    <xsl:template name="getpart">     <xsl:param name="xml" select="$xml"/>     <xsl:param name="stringrequired" select="$stringrequired"/>     <xsl:param name="xmllenfgh" select="$xmllenfgh"/>     <xsl:message>       <xsl:value-of select="$xml"/>     </xsl:message>     <xsl:if test="$xmllenfgh gt $stringrequired">       <t>         <x>           <xsl:value-of select="substring($xml,1,$stringrequired)"/>         </x>       </t>       <xsl:call-template name="getpart">         <xsl:with-param name="xml"           select="substring($xml,string-length(substring($xml,1,$stringrequired)))"/>         <xsl:with-param name="xmllenfgh"           select="string-length(substring($xml,string-length(substring($xml,1,$stringrequired))))"/>         <xsl:with-param name="stringrequired" select="$stringrequired"/>       </xsl:call-template>     </xsl:if>   </xsl:template> </xsl:stylesheet>
