3.6.1 Dynamic Variable Expansion
The variable selector allows for the use of dynamic variable expansion in conditions, actions, and
tokens. It is used when the writer of the DirXML script doesn’t know what value to enter during the
design phase, and wants the value to be populated dynamically when the code is run (for local
variables) or when the driver starts (for global variables). Dynamic variables are not used when the
policy needs to refer directly to the variable itself. Instead, they are used when the policy needs to
refer to the value of the variable.
Many actions support dynamic variable expansion in their attributes or content. Where supported, an
embedded reference of the form
$variable-name$ is replaced with the value of the local variable
with the given name. An embedded reference of the form ~variable-name~ is replaced with the
value of the global variable name. $variable-name$ and ~variable-name~ must be legal variable
names. For information on what constitutes a legal XML name, see W3C Extensible Markup
Language (XML) (http://www.w3.org/TR/2006/REC-xml11-20060816/#sec-suggested-names) .
If the given variable does not exist, the reference is replaced with the empty string. Where it is
desirable to use a single $ and not have it interpreted as a variable reference, use an additional $ as
an escape character (for example, You owe me $$100.00).
NOTE: If the global variable doesn’t exist on the driver or driver set, the driver does not start.
