Syntax

item of specified? attributes
  element-qualifier* {string-expression}


Purpose

item of attributes can be used to determine the order in which the attributes were declared. When specified, the first declared attribute has item number 1, the second has item number 2, and so on.

When item of is applied to an item on the attributes shelf, the key indexer, {...} indexer is required.

This example illustrates how item of can be used on the attributes shelf to determine the position of an item.

item of is used in this example to ensure that a line of text is output only when the "IDENT" attribute is the first one declared in its ATTLIST.

  output "IDENT is the first declared attribute%n"
        when item of attributes{"IDENT"} = 1
