[xsl] Batching into files using streaming

["Mailing Lists Mail daktapaal@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hello All,

I have this requirement :

I have to write an XSLT which will create files of a specific batch size.
For example
For 44 college elements and For batch size 10, the XSLT will produce 5
files with a max of 10 colleges in each fileb& There are elements preceding
and following <College> (country-info , Politics, sports, etcb&)and these
will have to be copied as is into each batch file

I tried the following code but I realized I am breaking the Streaming
rulesb&



<xsl:transform version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform
" xmlns:xs="http://www.w3.org/2001/XMLSchema";

            <xsl:mode name="batch" streamable="yes"
on-no-match="shallow-copyb/>

            <xsl:output method="xml" indent="yes"/>


            <xsl:param name="fileHref"
select="'file:///E:/stylesheets/TestBed/InputSource/University.xml'"/>

            <xsl:param name="BatchSize" select="10"/>

            <xsl:template match="/">

                        <xsl:stream href="{$fileHref}">

                                    <xsl:sequence>

                                                <xsl:for-each-group
select="/Country/University/Colleges/College" group-adjacent="(position()
-1) idiv $BatchSize">
<xsl:result-documenthref="file:///E:/stylesheets/TestBed/Result/CollegeBatch{
position()}.xml">


 <xsl:stream href="{$fileHref}">


             <xsl:sequence>


                         <xsl:apply-templates mode="batch">


           <xsl:with-param name="current-group"
select="current-group()"tunnel="yes"/>


                         </xsl:apply-templates>


             </xsl:sequence>


 </xsl:stream>


</xsl:result-document>

                                                </xsl:for-each-group>

                                    </xsl:sequence>

                        </xsl:stream>

            </xsl:template>

            <xsl:template match="*:Colleges" mode="batch">

                        <xsl:param name="current-group" tunnel="yes"/>

                        <BatchedColleges>

                                    <xsl:copy-of select="$current-group"/>

                        </BatchedColleges>

            </xsl:template>

</xsl:transform>



I tried to change for-each-group
to
<xsl:for-each-groupselect="/Country/University/Colleges/College/copy-of(.)"
group-adjacent="(position() -1) idiv $BatchSize">



Which works but does not copy the right Collegesb&or ends up completely
messing up with the numbers. Where did I go wrong ?


Your help is appreciated.
