Nah, that was the long approach, the shorter approach is just to use a
single xpath 2 expression:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="shipment">
<xsl:value-of select="' REC1*',header/string(shipmentId),
detail/po/(if(position() mod 2 = 1) then ' REC2*'
else '*', string()),
detail/containers/box/(if(position() mod 4 = 1) then
' REC3*' else '*',string())"
separator=""/>
</xsl:template>
</xsl:stylesheet>
That's a beauty!
Reading it, I much like the shortcut of deatil/po(if ...) etc. I then
hoped, that the if-statement could be replaced with a predicate, but
that wouldn't work, as the position() will then be about the sequence
and not the element, like here:
detail/po/(('*', ' REC2*')[position() mod 2 + 1], string())
and even if it worked, it'd be questionable whether it'd be clearer than
the if-syntax.
