Description

TXPathBooleanOpNode is a TXPathBinaryNode descendant used to represent an And or Or expression in XPath syntax. TXPathBooleanOpNode provides an overridden constructor that specifies the operator and operands for the XPath expression. TXPathBooleanOpNode contains an overridden Evaluate method which performs the comparison using Boolean short-circuit logic; i. e. the second operand is ignored if the result can be determined using the first operand.
