Description

GetValue is an overloaded function used to get the value stored in a DOM node at the path specified in APath. Overloaded variants are provided to return String, Integer, Int64, Boolean, and TRect data types. Other variants allow the arguments to be represented as various data types including untyped constants.

APath contain the path specifier that represents the hierarchy of elements and attributes in Document where the value is stored. See TXMLConfig Path Syntax for details about path specifiers.

ADefault contains the default value returned when the DOM node does not have any content representing a value.

ARect is the TRect output parameter used to return the value in the overloaded method.

Use GetExtendedValue to get the value for a DOM node as an Extended (or Float) data type.
