i have a pretty weird use case :

i have a node contained number of elements but late say i got 6 elements i only need to first 3.

<xsl:for-each select="/content/collaborator[position() &lt;= (last() div 2)]">
.

i know that this kind of things should be treated in data source
level

... , i'm using apache Fop to print my reports and i use the data that
comes thru a webservices so can't modify it .. any way in my xsl to use
only the NUMBER_OF_ELEMENT / 2 ?
