A ui:call to a select template allows you to set a variable name for an index.
See http://uispin.org/ui.html#forEach: <http://uispin.org/ui.html#forEach:>
As an optional argument of ui:forEach, the name of an index variable
can be provided using ui:indexVar. The value of this variable will be the
iteration counter, starting with 0.
There is also a “tops:for” function you could possibly use:
tops:for
This property can be used to implement loops over a range of integer values.
Syntax: ?index tops:for ( [startIndex] [endIndex] )
Description: The function iterates over all xsd:integer values >= startIndex
and <= endIndex and assigns all those values to the variable on the left side
Example: In the following query, the variable index will be bound to the
xsd:integer values 2, 3, and 4.
?index tops:for (2 4)
