Example
This example demonstrates how to use lst_del(L;D) to remove elements from
a list-value based on a list-value of index positions. In this case, the first three
elements of list-value L are removed.
<block name="list_funs" list_a="{lst(1 'a' 'b' 'c' 'd' 2 1)}" indexes="{lst(1 2 3)}"> <base table="default.lonely"/> <willbe name="remove_positions" label="Remove Positions" value="'{lst_del(@list_a;@indexes)}'"/> </block>
The list-value output from the lst_del(L;D) function as used above:
