Superx++ Lexicon: <expr> clause

<expr>

Purpose The <expr> clause is used to find multiple objects simultaneously that meet certain criteria. It is used in the <eval> statement.

Format <expr>
{finder expression}
<expr>

{finder expression} an expression that forms a valid rule that can be applied to find objects that conform to the rule

{value} is the value of the item
Find all objects with an item whose name is {item name} and whose value is {value}
any:xyz=400
will find all the nodes (or has an attribute, variable or array element) whose name is xyz whose value is 400.
